Answers

Answer 1

Answer:

I think A

Explanation:

Answer 2

Grams are the unit of weight or the mass that is the multiplication of the moles and the molar mass of the substance. The mass of hydrogen gas produced is 6.06 gm.

What is mass?

Mass is calculated in grams by multiplying the number of moles of the substance and the molar mass of the given molecule or compound.

Given,

Moles (n) of hydrogen = 3 mol

Molar mass of dihydrogen = 2.007 g/mol

Mass is calculated as:

[tex]\begin{aligned} \rm Mass &= \rm moles \times molar\; mass\\\\&= 3 \times 2.007\\\\&= 6.06\; \rm gm\end{aligned}[/tex]

Therefore, option D. 6.06 gm is the mass of hydrogen gas.

A gas is collected at 25.0 °C and 755.0 mm Hg. When the temperature is
changed to 0 °C, what is the resulting pressure?

Answers

Answer:

691.7 mmHg is the resulting pressure

Explanation:

Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:

P1T2 = P2T1

Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.

Computing the values of the problem:

T1 = 273 + 25 = 298K

P1 = 755.0mmHg

T2 = 273 + 0 = 273K

P2 = ?

755.0mmHg*273K = P2*298K

691.7 mmHg is the resulting pressure

What is the volume of a canister filled with gas if its pressure is changed to 9.8 atm from 2.5 atm at a volume of 9.1 L?

Answers

Answer:

2.3 L

Explanation:

A change in pressure-volume at constant temperature is described by the Boyle's law. The mathematical relationship between initial pressure and volume (P₁ and V₁) and final pressure and volume (P₂ and V₂) is given by:

P₁V₁ = P₂V₂

We have the following data:

initial pressure: P₁= 2.5 atm

initial volume: V₁ = 9.1 L

final pressure: P₂= 9.8 atm

Thus, we introduce the data in the mathematical expression and calculate the final volume V₂, as follows:

V₂ = P₁V₁/P₂ = (2.5 atm x 9.1 L)/9.8 atm = 2.3 L

Therefore, the volume of the canister is 2.3 L.

What is radioactive atom?

The smallest parts of common stuff that can be separated without releasing electrically charged particles are called atoms. The atoms are divided into two sections. an electron cloud and an atomic nucleus. Atoms with an unstable nucleus and the potential for radioactive decay are referred to as radioactive atoms.

As only nuclei often experience decay and changes with electron configuration only come from nucleus configuration changes, the term "radioactive atom" is misleading. This isn't a rule, it must be said. As a parent nucleus needs capture any of its orbital electrons, the electron cloud also plays a significant role in the case of electron capture. Its nucleus is unstable. This characterizes a radioactive atom.

Therefore, the correct option is option A.

What number should be in front of O2 to balance the equation?

Answers

Answer:

There are now two oxygen atoms on the left and four on the right (in one N2O and three H2O's), so we balance the oxygen atoms by placing a 2 in front of the O2.

The numbers before atoms are the coefficients, and they are used to balance chemical reacions. In the provided example, number in front of O₂ is 3.

Note: Since I do not have the proposed reaction, I provided a random example.

What is a balanced chemical reaction?

A balanced chemical reaction is an equation in which the number and type of atoms are the same on both sides of the arrows.

Following the law of mass conservation, chemical equations should be balanced to ensure that all the reactants appear in the products.

This means that no new atoms appear, and no atoms disappear. The only thing that changes in a chemical reaction is the bond between atoms.

So each side of the equation must be equilibrated concerning the amount and type of atoms.

Coefficients are used to balance reactions. These numbers are located before each atom and indicate the number of units present in the formula.

I do not have the proposed reaction, but I will provide an example using O₂.

4Al + _3_O₂ → 2 Al₂O₃

Reactants ⇒ 4 Al and 3 O₂

                     3 O₂ = 6 O

Products ⇒ 2 Al₂O₃

                    2 Al₂ = 4 Al

                    2 O₃ = 6 O

On each side of the equation we have 4 Al and 6 O. The only thing that changes are the bonds between atoms.

In this case, the coefficient of O₂ is 3.

How many grams of sucrose will I add to the water (0.100 L) in order to make the 3 molal solution.

Answers

Answer:

mass = 102.69 g of sucrose

Explanation:

First, you need to use the correct expression of molality (m) which is the following:

m = moles / kg solvent    (1)

According to the exercise, we need to get the grams, in other words, the mass of the sucrose. To get the mass, we need the moles and molecular weight of sucrose and use the following expression:

moles = mass / MM    (2)

Now, if we replace (2) in (1) we have:

m = mass / MM * kg solvent   (3)

From here, we solve for the mass and then:

mass = m * MM * kg solvent (4)

Now, then density of water is 1 kg/L, so, the volume of the water will be the same as it's mass, and the molality is 3 m. The molecular weight of the sucrose is (according to several sources) 342.3 g/mol. Replacing all the data in (4) we have:

mass = 3 mol/kg * 0.1 kg * 342.3 g/mol

mass = 102.69 g of sucrose

Three moles of oxygen gas is stored in a 2.5-liter container at 35°C. What is the pressure of this gas?

Answers

Answer:

30.34 atm

Explanation:

Using the general gas law formula;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

T = temperature (K)

R = gas law constant (0.0821 Latm/molK)

According to the information provided in this question,

n = 3mol

T = 35°C = 35 + 273 = 308K

V = 2.5L

P = ?

Using PV = nRT

P = nRT/V

P = 3 × 0.0821 × 308/2.5

P = 75.8604 ÷ 2.5

P = 30.34 atm.

sry if im wrong

There are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

To calculate the number of oxygen atoms in 75 g of SO₃, we need to consider the molar mass of SO₃ and Avogadro's number.

The molar mass of SO₃ is calculated as follows:

Sulfur (S) = 32.07 g/mol

Oxygen (O) = 3 x 16.00 g/mol = 48.00 g/mol

Total molar mass of SO₍ = 32.07 g/mol + 48.00 g/mol = 80.07 g/mol

Next, we need to determine the number of moles of SO₃ in 75 g:

moles = mass / molar mass = 75 g / 80.07 g/mol ≈ 0.9369 mol

Since each molecule of SO₃ contains 3 oxygen atoms, we can calculate the number of oxygen atoms by multiplying the number of moles of SO₃ by Avogadro's number (6.022 x 10²³ atoms/mol) and then multiplying by 3:

Number of oxygen atoms = 0.9369 mol x 6.022 x 10²³ atoms/mol x 3 = 1.604 x 10²⁴ atoms

Therefore, there are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.
