0.595 moles of water can be made at 112.6 grams of \(HNO_{3}\) are consumed

To determine the number of moles of water produced when 112.6 grams of \(HNO_{3}\) are consumed, we use the equation's stoichiometry and molar masses.

To determine the number of moles of water produced when 112.6 grams of \(HNO_{3}\) are consumed, we need to use the molar mass of \(HNO_{3}\) and the stoichiometric coefficients of the balanced chemical equation.

The molar mass of \(HNO_{3}\) is calculated as follows:

1 mole of hydrogen (H) = 1 g/mol

1 mole of nitrogen (N) = 14 g/mol

3 moles of oxygen (O) = 3 × 16 g/mol = 48 g/mol

Adding these together, the molar mass of \(HNO_{3}\) is 1 + 14 + 48 = 63 g/mol.

Now, we can set up a conversion factor using the stoichiometry of the balanced equation:

From the equation: 5 + 6 \(HNO_{3}\) -> \(H_{2}SO_{4}\) + 6 \(NO_{2}\) + 2 \(H_{2}O\)

From the coefficients: 6 moles of \(HNO_{3}\) produce 2 moles of \(H_{2}O\)

To find the moles of water produced, we use the following calculation:

112.6 g \(HNO_{3}\) × (1 mol \(H_{2}O\) / 63 g \(HNO_{3}\)) × (2 mol \(H_{2}O\) / 6 mol \(HNO_{3}\)) = 0.595 mol \(H_{2}O\)

Therefore, when 112.6 grams of \(HNO_{3}\) are consumed, approximately 0.595 moles of water can be produced according to the given balanced equation and molar masses.

Answer:

Water softening is the process of removing the dissolved calcium and magnesium salts that cause hardness in water

Explanation:

The diameter of the spherical nucleus of hydrogen-1 atom is 1 x 10^-13 cm. The density (g/cm3) of matter in a proton of mass of proton is 1.673 x 10^-24 is 3.193 × 10¹⁵ g/cm³.

The density of a substance is its mass per unit volume. The most common symbol for density is, but the Latin letter D can also be used. Density is defined mathematically as mass divided by volume.

Diameter = 1 x 10⁻¹³ cm

Mass = 1.673 x10⁻²⁴ g

Volume = 4/3πr³

Volume = 4/3 × 22/7 × (1 × 10⁻¹³ / 2)³

Volume = 11 × 10⁻³⁹ / 21

Density = Mass / Volume

           = 1.673 x10⁻²⁴ / 11 × 10⁻³⁹ / 21

Density = 3.193 × 10¹⁵ g/cm³

Thus, the density (g/cm3) of matter in a proton of mass of proton is 1.673 x 10^-24 is 3.193 × 10¹⁵ g/cm³.

The volume of O₂ produced when 8.52 g of Na₂O₂ is added to excess water is approximately 1.17 liters at STP.

When it comes to the ideal gas law, the underlying assumption is that the gas is in a state of thermodynamic equilibrium. This means that its molecules are not interacting with each other except through perfectly elastic collisions.

Equation:

We can use stoichiometry to determine the volume of oxygen gas produced from the reaction of 8.52 g of Na₂O₂.

First, we need to convert the mass of Na₂O₂ to moles using its molar mass:

8.52 g Na₂O₂ × (1 mol Na₂O₂ / 77.98 g Na₂O₂) = 0.1093 mol Na₂O₂

According to the balanced chemical equation, 1 mole of Na₂O₂ produces 1/2 mole of O₂:

2 Na₂O₂ + 2 H₂O → 4 NaOH + O₂

1 mol Na₂O₂ produces 1/2 mol O₂

So, the number of moles of O₂ produced is:

0.1093 mol Na₂O₂ × (1/2 mol O₂ / 1 mol Na₂O₂) = 0.05465 mol O₂

Finally, we can use the ideal gas law to determine the volume of O₂ produced at standard temperature and pressure (STP), which is defined as 0°C (273 K) and 1 atmosphere (1 atm) of pressure:

PV = nRT

At STP, the pressure and temperature are known, so we can rearrange the equation to solve for V:

V = nRT / P

Plugging the values, we get:

V = (0.05465 mol) × (0.08206 L atm mol⁻¹ K⁻¹) × (273 K) / (1 atm)

V ≈ 1.17 L

The mass of the asteroid is C. 1.2 x \(10^{12}\) Kg

To find the mass of the other asteroid, we can rearrange the equation for the gravitational force between two objects:

F = (G * m1 * m2) / \(r^{2}\)

where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two asteroids, and r is the distance between them.

Given that the distance between the asteroids is 75000 m, the force of gravity between them is 1.14 N, and one asteroid has a mass of 8 x \(10^{7}\) kg, we can substitute these values into the equation and solve for the mass of the other asteroid (m2):

1.14 N = (6.67430 × \(10^{-11}\) N \(m^{2}\)/\(Kg^{2}\) * 8 x \(10^{7}\) kg * \(m2\)) / \((75000 m)^{2}\)

Answer:

You need 85.32 grams of KMnO₄ to produce 0.27 moles of O2, assuming 100% conversion.

Explanation:

The balanced chemical reaction is:

2 KMnO₄ (s) → K₂MnO₄ (s) + MnO₂ (s) + O₂ (g)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 1 mole of O₂ is produced by 2 moles of KMnO₄, 0.27 moles of O₂ are produced by how many moles of KMnO₄?

\(moles of KMnO_{4} =\frac{0.27 moles of O_{2} *2moles of KMnO_{4} }{1mole of O_{2} }\)

moles of KMnO₄= 0.54

The molar mass of KMnO₄ is 158 \(\frac{g}{mol}\).

Then the amount of mass present in 0.54 moles of the compound can be calculated by:

0.54 moles* 158.034 \(\frac{g}{mol}\)= 85.32 grams

You need 85.32 grams of KMnO₄ to produce 0.27 moles of O2, assuming 100% conversion.

Answer:10

Explanation:

Answer:

Explanation:

The relative speed and distance of atoms in a substance depend on the state of matter.

In a solid, atoms are closely packed together and have minimal movement or vibration. Their relative speed is low and their distance from one another is short.

In a liquid, atoms are still close together but have more movement and freedom of movement than in a solid. Their relative speed is slightly higher than in a solid, and their distance from one another is slightly longer.

In a gas, atoms are widely spaced and have a high degree of movement and freedom of movement. Their relative speed is much higher than in a solid or liquid, and their distance from one another is much greater.

In a plasma, atoms are ionized and have a high degree of movement and freedom of movement. Their relative speed is much higher than in a solid, liquid or gas, and their distance from one another is much greater.

B. the volume of the gas to increase.

Thermal energy is the energy associated with the random motion of the particles in a substance, such as a gas. When thermal energy is added to a gas at constant pressure, the increased kinetic energy of the gas particles causes them to move apart, increasing the volume of the gas. This relationship is described by Gay-Lussac's Law, which states that at a constant pressure, the volume of a gas is directly proportional to its temperature.

Answer:

pH = 4.25

Explanation:

A solution composed of a weak acid and its conjugate base is a buffer solution. To calculate the pH of a buffer solution we use the Henderson-Hasselbach equation:

pH = pKa + log ([conjugate base]/[weak acid]

In this case, we have the following data:

[conjugate base] = [sodium benzoate] = 0.230 M

[weak acid] = [benzoic acid] = 0.205 M

The pKa of benzoic acid is 4.2. So, we introduce the data in the equation:

pH = 4.2 + log (0.230 M/0.205 M) = 4.2 + 0.050 = 4.25
