find the volume of a gas at standard pressure if its volume at 1.9 atm is 80 ml?

given:
formula:
substitution:
answer:

Answers

Answer 1

Answer:

1.5 × 10² mL

Explanation:

Step 1: Given data

Initial pressure of the gas (P₁): 1.9 atmInitial volume of the gas (V₁): 80 mLFinal pressure of the gas (P₂): 1.0 atm (standard pressure)Final volume of the gas (V₂): ?

Step 2: Calculate the final volume of the gas

For an ideal gas, we can calculate the final volume of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 1.9 atm × 80 mL/1.0 atm

V₂ = 1.5 × 10² mL

Since the pressure decreased, the volume of the gas increased.

Consider the following equilibrium.
NH3(aq) + H2O(l) equilibrium reaction arrow NH4+(aq) + OH −(aq)
What will happen to the equilibrium constant if the concentration of OH − increases through the addition of a small amount of NaOH(aq)?

Answers

Answer:

It will remain the same

Explanation:

The equilibrium constant of the reaction will remain the same if the concentration of the OH is increased.

Changes in concentration values of any of the reactant does not affect the value of the equilibrium constant.

The equilibrium constant is a constant at a given temperature. It is temperature dependent. Since we have no change in temperature, therefore, the equilibrium constant will not change.

The equilibrium constant if the concentration of OH − increases through the addition of a small amount of NaOH(aq) is :

- Remains same.

Equilibrium Reaction

The equilibrium constant of the response will stay the same in case the concentration of the OH is increased.

Changes in concentration values of any of the reactant does not influence the esteem of the equilibrium constant.

The equilibrium constant may be a consistent at a given temperature.

It is temperature dependent. Since we have no alter in temperature.

In an aqueous solution, a 0.100 M solution of glucose is prepared with a total volume of 0.150 Liters. If the molar mass of glucose is 180.16 g/mol how many grams must the solution contain?

Answers

Answer:

2.70 g of glucose.

Explanation:

The following data were obtained from the question:

Molarity of the glucose solution = 0.1 M

Volume of solution = 0.15 L

Molar mass of glucose = 180.16 g/mol

Mass of glucose =.?

Next, we shall determine the number of mole of glucose in the solution. This can be obtained as follow:

Molarity of the glucose solution = 0.1 M

Volume of solution = 0.15 L

Mole glucose =?

Molarity = mole /Volume

0.1 = Mole of glucose /0.15

Cross multiply

Mole of glucose = 0.1 × 0.15

Mole of glucose = 0.015 mole

Finally, we shall determine the mass of glucose in the solution as follow:

Mole of glucose = 0.015 mole

Molar mass of glucose = 180.16 g/mol

Mass of glucose =.?

Mole = mass /molar mass

0.015 = mass of glucose /180.16

Cross multiply

Mass of glucose = 0.015 × 180.16

Mass of glucose = 2.70 g

Therefore, the solution contains 2.70 g of glucose.

The grams that the solution must contain is :

- 2.70 g of glucose.

Mole Concept

Given:

Molarity of the glucose solution = 0.1 M

Volume of solution = 0.15 L

Molar mass of glucose = 180.16 g/mole

Molarity of the glucose solution = 0.1 M

Volume of solution = 0.15 L

Molarity = mole /Volume

0.1 = Mole of glucose /0.15

Mole of glucose = 0.1 × 0.15

Mole of glucose = 0.015 mole

Mole of glucose = 0.015 mole

Molar mass of glucose = 180.16 g/mol

Mass of glucose =.?

Mole = mass /molar mass

0.015 = mass of glucose /180.16

Mass of glucose = 0.015 × 180.16

Mass of glucose = 2.70 g

The solution contains 2.70 g of glucose.

C. The number of atoms or molecules does not affect the thermal energy of a system.
D. Thermal energy increases as the atoms and molecules in a system move more.

Answers

Answer:

D. Thermal energy increases as the atoms and molecules in a system move more.

Explanation:

Thermal energy is a form of kinetic energy possessed by molecules of a system. The measure of this kinetic energy in an atom is called heat.

The average kinetic energy of a system is the temperature.

According to the kinetic theory, the more the particles move, the more their thermal energy. Thermal energy is often predicated on the velocity of the particles of the medium.

Explanation:

In warm temperatures, cold-blooded animals are more active and can travel more quickly. This occurs because heat activated reactions provide energy to move muscles. In the absence of heat the animal becomes slow and sluggish. So they are usually inactive and rest when it is cold. As they do not need to feed much, they spend less time looking for food, so this life strategy works for them.

Determine the volume (mL) of 15.0 M sulfuric acid needed to react with 45.0 g of
aluminum to produce aluminum sulfate.

Answers

Answer:

167 mL.

Explanation:

We'll begin by calculating the number of moles in 45 g of aluminum (Al). This can be obtained as follow:

Mass of Al = 45 g

Molar mass of Al = 27 g/mol

Mole of Al =?

Mole = mass /Molar mass

Mole of Al = 45/27

Mole of Al = 1.67 moles

Next, the balanced equation for the reaction. This is given below:

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

From the balanced equation above,

2 moles of Al reacted with 3 moles of H2SO4.

Next, we shall determine the number of mole of H2SO4 needed to react with 45 g (i.e 1.67 moles) of Al. This can be obtained as:

From the balanced equation above,

2 moles of Al reacted with 3 moles of H2SO4.

Therefore, 1.67 moles of Al will react with = (1.67 × 3)/2 = 2.505 moles of H2SO4.

Thus 2.505 moles of H2SO4 is needed for the reaction.

Next, we shall determine the volume of H2SO4 needed for the reaction. This can be obtained as follow:

Molarity of H2SO4 = 15.0 M

Mole of H2SO4 = 2.505 moles

Volume =?

Molarity = mole /Volume

15 = 2.505 / volume

Cross multiply

15 × volume = 2.505

Divide both side by 15

Volume = 2.505/15

Volume = 0.167 L

Finally, we shall convert 0.167 L to mL. This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.167 L = 0.167 L × 1000 mL / 1 L

0.167 L = 167 mL

Thus, 0.167 L is equivalent to 167 mL.

Therefore, 167 mL H2SO4 is needed for the reaction.

facts o.o

Nuclear power plants pollute the environment and causes cancer in populations that use nuclear energy instead of traditional electricity. Hence option A is correct.

What is nuclear power plant?

Nuclear power plant is defined as a particular kind of power plant that produces electricity by nuclear fission. Nuclear power plants use the heat generated by nuclear fission to transform water into steam in a controlled environment, which then powers generators to produce electricity.  Low-enriched uranium fuel is used in nuclear power plants to generate electricity through a process known as fission, which involves breaking uranium atoms in a nuclear reactor.

A clean energy source with no emissions is nuclear. It produces energy by fission, which is the splitting of uranium atoms to release energy. Without the toxic consequences that come from burning fossil fuels, electricity is produced using the heat from fission to produce steam, which turns a turbine.

Thus, nuclear power plants pollute the environment and causes cancer in populations that use nuclear energy instead of traditional electricity. Hence option A is correct.
