How many grams of NaCl are produced when 1.25 moles of Cl2 reacts with Na?

Answers

Answer 1

Explanation:

2/1×1.25

=2.5 mole of NaCl are produced

weight of NaCl produced = moles × molar mass of NaCl

Where does much of our history of Precambrian rocks come from? fossils on the rock surface ores mined from shields ash taken from volcanoes trenches on the sea floor

Answers

Answer:

Ores mined from shields.

Explanation:

Ores mined from shields are the source from which we get the history of Precambrian rocks. The Ores from shield experience the Precambrian era so that's why its rocks provides information about that era. The Precambrian supereon is the division of the geological time scale which is the first and longest stage in the history of the Earth which also includes the Hádic, Archaic and Proterozoic eons.

A scientist plans the react 9.0x10^-2 L NO held at a pressure of 200.0kPa and a temperature of 20.0 C with excess hydrogen. How many moles of nitrogen gas will be produced

Answers

Answer:

[tex]n_{N_2}=0.00369molN_2[/tex]

Explanation:

Hello there!

In this case, by firstly setting up the described chemical reaction, we are able to write:

[tex]2NO(g)+2H_2(g)\rightarrow N_2(g)+2H_2O(g)[/tex]

Thus, given the pressure (convert to atm), volume and temperature (convert to K) we can calculate the moles of NO:

[tex]n=\frac{PV}{RT}\\\\n=\frac{200.00/101.325atm*0.090L}{0.08206\frac{atm*L}{mol*K}*(20.0+273.15)K} \\\\n=0.00738molNO[/tex]

Next, we use the 2:1 mole ratio of NO to N2 to obtain the moles of nitrogen gas that will be produced:

[tex]n_{N_2}=0.00738molNO *\frac{1molN_2}{2molNO} \\\\n_{N_2}=0.00369molN_2[/tex]

Answers

Answer:

D, The volume will be multiplied by a factor of 4

Explanation:

First find the height

V = π(r^2)h

Plug in what we know

83 = π(3^2)h

83 = π(9)h

83  = (9π)h

9[tex]\pi[/tex] = 28.27

83/28.27 = (28.27)h/28.27

h = 2.94

Then find the volume of the new can by doubling the radius

3 x 2 = 6

r = 6

V = π(r^2)h

V = π(6^2)2.94

V = π(105.84)

V =332.51

For the first one, they rounded to the nearest whole #, so let's do the same.

V = 333

Then divide 333 by 83 to get 4

Therefore, the volume will be multiplied by a factor of 4

Provide one example where a neutralization reaction is undesired/harmful. State the reactants and explain why it is harmful for this reaction to take place.

Answers

Answer:

You're in my science class wth

Explanation:

For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?

Answers

Answer: The new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.

Explanation:

Given: [tex]V_{1}[/tex] = 10.0 mL,      [tex]M_{1}[/tex] = 2.0 M

[tex]V_{2}[/tex] = 100 mL,           [tex]M_{2}[/tex] = ?

Formula used to calculate the new concentration is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M[/tex]

Thus, we can conclude that the new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.

a. number of isotopes.
b average atomic mass
c avogradro constant
d atomic number​

Answers

Answer:

d

Explanation:

from you know the atomic number it should be easy to find

To determine the molar mass of an element, one must know the element's atomic number​. Therefore, option D is correct.

What is the atomic number ?

An element's atomic number (Z) is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the feature that distinguishes each element from all others. Elements differ based on their atomic number.

Because the combined masses of protons and neutrons account for nearly all the mass of a given atom, the atomic mass of a single atom can be calculated by adding the total number of protons and neutrons of that particular isotope.

The atomic mass of any element on the periodic table can be used to calculate its molar mass.

Thus, option D is correct.

A good year blimp (a huge airship) is filled to a
volume of 1,800L at a temperature of 35°C. As
the weather changed the blimp is then cooled
at constant pressure to a temperature of -46°C.
What is the final volume of the blimp?

Answers

Answer:

V₂ = 1326.62 L

Explanation:

Given that,

Initial volume, V₁ = 1800 L

Initial temperature, T₁ = 35°C = 308 K

Final temperature, T₂ = -46°C = 227 K

We need to find the final volume of the blimp. The relation between volume and temperature is given by :

[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{1800\times 227}{308}\\\\V_2=1326.62\ L[/tex]

So, the final volume of the blimp is 1326.62 L.
