100. cal of heat are added to 18.0 g of ethanol (0.581 cal/g °C) originally at 23 °C. The final temperature is ____________.

Answers

Answer:

Final temperature is 32.56 °C

Explanation:

The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1°C.

The following equation/formula is used;

Q = m × c × ΔT

Where; Q= amount of heat supplied

(cal)

M= mass of ethanol (g)

C= specific heat of ethanol

(cal/g °C)

ΔT= change in temperature (°C)

i.e. (final temperature - initial

temperature)

According to the question, Q= 100 calories (cal), M= 18g, C= 0.581 cal/g °C, initial temperature = 23°C, final temperature = ?

Hence, we insert our values into the equation;

Q = m × c × ΔT

ΔT = Q/mc

(Final T - Initial T) = Q/mc

(Final T - 23) = 100/ 18 × 0.581

(Final T - 23) = 100/10.458

Final T - 23 = 9.562

Final T = 23 + 9.562

Final T = 32.562

Hence, the final temperature of ethanol is 32.56°C

A hot needle sinks when put on the surface of cold water. Will a cold needle float or sink in warm water?

Answers

Answer:

sink

Explanation:

The Intermolecular force of attraction exists within the water molecule. This type of intermolecular force of attraction is known as a hydrogen bond. A hydrogen bond is a dipole-dipole intermolecular attraction that occurs when hydrogen is covalently bonded to highly electronegative elements of a small atomic size.

When the heat is applied to this intermolecular force, the heat disrupts the intermolecular force, and the surface tension is being broken. This is what caused a hot needle to sink when placed in cold water. But when a cold needle is placed on the surface of warm water, the cold needle will not break up the warm water's surface tension. As a result, the cold need sinks in the warm water.

Ammonia reacts with diatomic oxygen to form nitric oxide and water vapor: 4 NH3 + 5 O2 → 4 NO + 6 H2O When 40.0 g NH3 and 50.0 g O2 are allowed to react, what is the mass of the remaining excess reagent?

Answers

Answer:

18.75 g of NH3.

Explanation:

The balanced equation for the reaction is given below:

4NH3 + 5O2 → 4NO + 6H2O

Next, we shall determine the masses of NH3 and O2 that reacted from the balanced equation.

This can be obtained as follow:

Molar mass of NH3 = 14 + (3x1) = 17 g/mol

Mass of NH3 from the balanced equation = 4 x 17 = 68 g

Molar mass of O2 = 16x2 = 32 g/mol

Mass of O2 from the balanced equation = 5 x 32 = 160 g

From the balanced equation above,

68 g if NH3 reacted with 160 g of O2.

Next, we shall determine the excess reactant. This can be obtained as follow:

From the balanced equation above,

68 g if NH3 reacted with 160 g of O2.

Therefore, 40 g of NH3 will react with = (40 × 160)/68 = 94.12 g of O2.

From the calculations made above, we can see that it will take a higher amount of O2 i.e 94.12g than what was given i.e 50g to react completely with 40 g of NH3.

Therefore, O2 is the limiting reactant and NH3 is the excess reactant.

Next we shall determine the mass of excess reactant that reacted. This can be obtained as follow:

From the balanced equation above,

68 g if NH3 reacted with 160 g of O2.

Therefore, Xg of NH3 will react with 50 g of O2 i.e

Xg of NH3 = (68 × 50)/160

Xg of NH3 = 21.25 g

Therefore, 21.25 g of NH3 (excess reactant) were consumed in the reaction.

Finally, we shall determine mass of the remaining excess reactant as follow:

Mass of excess reactant = 40 g

Mass of excess reactant that reacted = 21.25 g

Mass of excess reactant remainig =?

Mass of excess reactant remainig = (Mass of excess reactant) – (Mass of excess reactant that reacted)

Mass of excess reactant remainig

= 40 – 21.25

= 18.75 g

Therefore, the mass of excess reactant remaining is 18.75 g of NH3.

A 194-g sample of caffeine (C3H10 N4O2) contains 6.02 x 10^23 molecules of
caffeine. If some energy drink contains 210. mg of caffeine, how many molecules of caffeine are present in the drink?

Answers

Answer:

6.52×10²⁰ molecules.

Explanation:

We'll begin by converting 210 mg of caffeine to grams (g). This can be obtained as follow:

Recall:

1 mg = 1×10¯³ g

Therefore,

210 mg = 210 mg / 1 mg × 1×10¯³ g

210 mg = 0.21 g

Therefore, 210 mg of caffeine is equivalent to 0.21 g of caffeine.

Finally, we shall determine the number of molecules in 0.21 g of caffeine as follow:

194 g of caffeine contains 602×10²³ molecules.

Therefore, 0.21 g of caffeine will contain = (0.21 × 602×10²³)/194 = 6.52×10²⁰ molecules.

Therefore 0.21 g contains 6.52×10²⁰ molecules.

Thus, we can say that 210 mg (i.e 0.21g) of caffeine contains 6.52×10²⁰ molecules.

Compound A, C7H13Br, is a tertiary alkyl bromide. On treatment with CH3CH2ONa, A is converted into B, C7H12. Ozonolysis of B with O3 gives C as the only product. What are the structures of compounds A and B

Answers

Answer:

Compound A:    1-bromo-1-methylcyclohexane

Compound B:     1-methylcyclohex-1-ene

Explanation:

In this question, we can start with the I.D.H (hydrogen deficiency index):

[tex]I.D.H~=~\frac{(2C)+2+(N)-(H)-(X)}{2}[/tex]

In the formula we have 7 carbons, 13 hydrogens, and 1 Br, so:

[tex]I.D.H~=~\frac{(2*7)+2+(0)-(13)-(1)}{2}=1[/tex]

We have an I.D.H value of one. This indicates that we can have a cyclic structure or a double bond.

We have to keep in mind that the Br atom must be bonded to a tertiary carbon. We can not have a double bond because in the ozonolysis reaction we have only 1 product, therefore, we can not have a double bond in the initial molecule (if we have a double bond in the initial molecule we will have more than 1 product in the ozonolysis reaction).

With this in mind, we will have a cyclic structure. If we have 7 carbons and we need a tertiary alkyl halide. We can have a cyclic structure of 6 members and a methyl group bonded to a carbon that also is bonded to a Br atom (1-bromo-1-methylcyclohexane).

In the reaction with [tex]CH_3CH_2ONa[/tex] we will have an elimination reaction. In other words, we have the production of a double bond inside of the cyclic structure (1-methylcyclohex-1-ene).

space contains, on average, 6 x 10^15 solar-wind ions.

How many miles of ions are in a cubic kilometer of near- Earth space?

Answers

Answer:

There are [tex]6\times 10^{12}[/tex] miles of ions in a cubic kilometer of near-Earth space.

Explanation:

In this context, we must be clear on stating that words miles is a synonym for thousands. In other words, the question may be rewritten to this form: How many thousand of ions are in a cubic kilometer of near-Earth space? In engineering notation, a thousand is represented by:

[tex]x = 10^{3}[/tex]

As we know the average quantity of solar-wind ions in a cubic kilometer of interplanetary space near Earth, we need to make quick conversion to determine the quantity of miles of ions by this formula:

[tex]y = n\cdot 10^{-3}[/tex]

Where:

[tex]n[/tex] - Quantity of solar-wind ions, measured in units.

[tex]y[/tex] - Quantity of solar-wind ions, measured in thousands (or miles).

If we know that [tex]n = 6\times 10^{15}\,units[/tex], then:

[tex]y = (6\times 10^{15}\,units)\cdot \left(10^{-3}\,\frac{miles}{unit} \right)[/tex]

[tex]y = 6\times 10^{12}\,miles[/tex]

There are [tex]6\times 10^{12}[/tex] miles of ions in a cubic kilometer of near-Earth space.

Sort these molecules into the appropriate bin according to their polarity.Drag the appropriate items to their respective bins.HBr CO2 BF3 H2 CH4 NH3Polar Non polar

Answers

Explanation:

Generally, polar molecules contain polar bonds that arise as a result of the difference in electronegativities of the elements in the molecule. In most instances, molecules containing a metal and a non metal are polar in nature.

HBr - This molecule has two opposite sides of polarity, a group 1 and group 7 element. It is polar

CO2 - The bond between C and O is polar however, there is a cancellation of the polar bonds due to how the atoms are arranged. It is non polar.

BF3 - There is no net dipole (separation of charges) in this compound hence it is non polar.

H2 - Covalent molecules made up of only one type of atom are non polar.

CH4  - This is non polar as the difference in electronegativities between C and H is not great enough to form a dipole.

NH3 - The polar bonds (N-H) do not cancel each other out. Hence this molecule is polar.

Kinetic energy is simply defined as energy possed by a body in motion. Mathematically, it is expressed as:

K.E = ½mv²

Where:

K.E is the kinetic energy

m is the mass of the object

v is the velocity of the object.

Thus, we can obtain the kinetic energy of the automobile by using the above formula as illustrated below:

Mass (m) = 1250 kg

Velocity (v) = 20.0 m/s.

Kinetic energy (K.E) =?

K.E = ½mv²

K.E = ½ × 1250 × 20²

K.E = 625 × 400

K.E = 250000 J

Therefore, the kinetic energy of the automobile is 250000 J

[tex]^{14}_{6} C[/tex] is a radioactive isotope with a halflife of 5568 years. The decay of any radioisotope is modelled after the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m}{\tau}[/tex]

Where:

[tex]m[/tex] - Current mass of the isotope, measured in grams.

[tex]\tau[/tex] - Time constant, measured in years.

The solution of this equation is of the form:

[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex]

Where:

[tex]t[/tex] - Time, measured in years.

[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.

The time constant can be found as a function of halflife ([tex]t_{1/2}[/tex]):

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex]

If [tex]t_{1/2} = 5568\,yrs[/tex] and [tex]t = 3000\,yrs[/tex], the mass fraction of [tex]^{14}_{6} C[/tex] is:

[tex]\tau = \frac{5568\,yrs}{\ln 2}[/tex]

[tex]\tau \approx 8032.926\,yrs[/tex]

[tex]\frac{m(3000\,yrs)}{m_{o}} = e^{-\frac{3000\,yrs}{8032.926\,yrs} }[/tex]

[tex]\frac{m(3000\,yrs)}{m_{o}} \approx 0.688[/tex]

The current mass fraction of [tex]^{14}_{6} C[/tex] should be approximately 68.8 percent.
