How much heat, in joules, does it take to raise the temperature of 225. 0 g of water from 25. 0°c to 100. 0°c ?.

Answers

Answer 1

The amount of heat required to raise the temperature of 225.0 g of water from 25.0°C to 100.0°C is equal to 67,837 joules.

What is temperature?
A physical quantity known as temperature expresses the concepts of hotness as well as coldness in numerical form. With a thermometer, temperature is measured. Thermometers are calibrated using a number of temperature scales which historically defined various reference points as well as thermometric substances. The most widely used scales are the Kelvin scale (K), which is primarily used for scientific purposes, the Fahrenheit scale (°F), as well as the Celsius scale (°C), formerly known as centigrade, with the unit symbol °C. In the Worldwide System of Units, one of the eight base units is the kelvin (SI).

The amount of heat, in joules, required to raise the temperature of 225.0 g of water from 25.0°C to 100.0°C can be calculated using the equation:
Q = mcΔT
where
Q = heat in joules,
m = mass of the water in grams,
c = specific heat capacity of water,
ΔT = change in temperature (100.0°C – 25.0°C = 75.0°C).

Using these values, the equation can be rearranged to:
Q = (225.0 g) (4.184 J/g°C) (75.0°C)

Therefore, the amount of heat required to raise the temperature of 225.0 g of water from 25.0°C to 100.0°C is equal to 67,837 joules.

nuclear decay occurs according to first-order kinetics. a nuclide decays in 3.40 days from 45.0 g to 12.1 g. what is the rate constant for the nuclide?

Answers

The rate constant for the nuclide according to first-order kinetics is 0.3863 per day.

Nuclear Decay in First-Order Kinetics:

m(t) = Me∧(-αt)

where m(t) = mass of nuclide after decay at time t;

M = mass of nuclide before decay;

α = rate constant of decay;

t = time for the decay;

What is first-order kinetics?

When a fixed percentage of the drug is excreted per unit of time, this is known as first-order kinetics.

For example, The amount of drug in the body has a direct relationship to the rate of removal. The amount of medication eliminated per unit of time increases with concentration. The medication concentration decreases by 50% for each half-life.

Now,

m(t) = Me∧(-αt)

⇒e∧(αt) = M/m(t)

applying ln on both sides;

αt = ln(m/m(t))

α = (ln(m/m(t))/t)

here t= 3.4 days, M = 45 grams, m(t) = 12.1 grams;

dropping these values in the above equation we get,

α = 0.3863 per day;

what is the edge length of a body-centered cubic unit cell made up of atoms that each has a radius of 178 pm ?

Answers

The edge length of a body-centered cubic unit cell made up of atoms of radius 178 pm is 411.074 pm.

The body-centered cubic unit cell is defined as an unit cell that has atoms at each of the eight corners of a cube (like the cubic unit cell) plus one atom present in the center of the cube. Each of the corner of  atoms is the corner of another cube so the corner atoms are shared among eight unit cells.

Length of body diagonal = r + 2r + r

                                         = 4r

From the cube, body diagonal = √(3) a

∴ 4r = √(3) a

Where:

a: is the edge length

R: is the radius of each atom = 178 pm      

By solving equation the equation for "a" we have:

a = 4r/√(3)

Answers

Polonium has a simple cubic cell(1 atom), manganese has a body-centered cube(2 atoms) and Silver is a face-centered cubic cell(4 atoms).

In each of the 3 unit cells of the metals, for every corner of the cell, there is 1/8th volume of the sphere. The total volume of the sphere is given by,

Total volume = 1/8th corner of cube x 8 Total Volume

                      = 1 sphere or atom

Hence, Polonium has only one atom in its cell whereas Manganese has 2 atoms in its cell, one in the corner and one in the center of the cell.

In the case of silver, apart from the corners in each of the faces, there is one hemisphere in each of the faces. There are 6 such faces in the cell. Therefore the number of atoms in silver is given by,

No of atoms in silver = 6 x 1/2 + 8 x 1/8

The key to this problem is the fact that each component of a gas mixture contributes to the total pressure exerted by the mixture in proportion to the number of molecules in the mixture.

Partial pressures of gases are most often expressed as mole fractions.

Now, the percentage composition of a gas mixture is the number of molecules each gas contributes to 100 molecules of the mixture.

In this case, the air must contain 0.04% carbon dioxide. This means that there are 0.04 CO₂ molecules in 100 air molecules.

Limestone forms as ocean water evaporates and leaves calcium carbonate behind, which is then deposited on the ocean floor. what type of rock can be formed in this way?

Answers

Sedimentary rocks include limestone. When ocean water evaporates, calcium carbonate is left behind, and this is how it forms.

Limestone is one of the most common types of chemical rocks. Limestone is created in the ocean by calcium and bicarbonate ions that erode from the remains of shells, coral, crustaceans, and mollusks. Wave action gradually disintegrates these structures into calcite and other calcium carbonate-based minerals, which accumulate in ocean water. As they are carried from the deep ocean environment to shallow places like lagoons and tidal pools, these solutes have the potential to precipitate to create sediments rich in calcium carbonate.  calcium carbonate can precipitate in lagoons to create ooids, which are spherical nodules that stick together to produce oolitic limestone, or limestone.

to a 1 l solution of 0.1 m acetic acid solution, 20 g of sodium acetate is dissolved. what is the ph of the solution

Answers

The pH of the given solution would be 4.75.

What do you mean by pH?

pH is a measure of the acidity or alkalinity of a solution, usually expressed on a scale from 0 to 14. A pH of 7 is neutral, with solutions below 7 being acidic and solutions above 7 being alkaline.

The pH of the solution can be calculated using the Henderson-Hasselbalch equation:

pH = pKa + log([salt]/[acid])

Where pKa is the -log of the acid dissociation constant (in this case, 4.75 for acetic acid), [salt] is the molar concentration of the salt (in this case, 0.1 M for sodium acetate), and [acid] is the molar concentration of the acid (in this case, 0.1 M for acetic acid).

Plugging in the values, we get

pH = 4.75 + log(0.1/0.1)

pH = 4.75

Therefore, the pH of the solution is 4.75.

Given,

mass of the ethanol (m) = 25.02g

heat capacity of the ethanol (c) = 2.46

Conversion of Kelvin to Celsius:

C = K - 273.15

C2 = 351.5 - 273.15 => 78.35 C

             

Formula:

H = mcdT                

temperature change (dT) = C2 -C1 => 78.35 - 15.99 => 62.36 C
