If we put 100 particles of heavy species of gas into a container and the pressure is 12
atmospheres, predict the new pressure of putting a total of 300 particles of this gas
into the container.

A - 12 atm

B- 36 atm

C- 24 atm

Answers

Answer 1

The new pressure of the particles of heavy species of gas is 36 atm.

The correct option is B

What is the new pressure of the gas?

The new pressure of the particles of heavy species of gas is determined  using the ideal gas equation as follows:

PV = nRT

where;

P is the pressureV is the volume n is the number of particlesR is the molar gas constant

T is the temperature

Assuming the temperature, volume, and molar gas constant all remain unchanged, the new equation will be:

P = n

When n = 100, P = 12 atm

Ratio of n and P = 100/12

When, n = 300, P = 300 * 12/100

Pressure = 36 atm

Hydrogen (H₂) gas and oxygen (O₂) gas react to form water (H₂O) vapor. Suppose you have 3.0 mol of H₂ and 7.0 mol of O₂ in a reactor.
Suppose as much as possible of the H₂ reacts. How much will be left? Round your answer to the nearest 0.1 mol.

Answers

Answer:

1.5 moles

Explanation:

The balanced chemical equation for this reaction is:

2H₂ + O₂ → 2H₂O

This means that 2 moles of hydrogen reacts with 1 mole of oxygen to form 2 moles of water.

Since we have 3.0 moles of hydrogen and 7.0 moles of oxygen, the limiting reactant will be hydrogen (H₂). The amount of oxygen that can react with the available hydrogen is equal to half the amount of hydrogen, which is (3.0 moles / 2) = 1.5 moles.

So, after the reaction, we will have 3.0 moles - 1.5 moles = 1.5 moles of hydrogen left. Rounding to the nearest 0.1 mol, the answer is 1.5 moles.

determine the total, carbonate, and noncarbonate hardness in mg/l as caco3 and in meq/l for the water analysis in problem 7.5

Answers

The total hardness = 2.84 meq/L, carbonate hardness = 2.84 meq/L, and noncarbonate hardness = 0 meq/L.

What is hardness of water?

Hardness of water refers to the presence of dissolved minerals, specifically calcium and magnesium ions, in the water. Hard water is water that has a high concentration of these minerals, which can cause issues in household appliances and plumbing, as well as affect the taste and lather quality of soaps and detergents.

To determine the total, carbonate, and noncarbonate hardness in mg/L as CaCO3 and in meq/L, you need to follow the following steps:

Calculate the total hardness:

The total hardness can be calculated using the equation:

Total hardness (mg/L as CaCO3) = (Calcium (mg/L) + Magnesium (mg/L)) × 2.5.

In this case, the total hardness = (67.2 + 40) × 2.5 = 284 mg/L as CaCO3

Calculate the carbonate hardness:

The carbonate hardness can be calculated using the equation:

Carbonate hardness (mg/L as CaCO3) = Alkalinity (mg/L as CaCO3) - (Bicarbonate (mg/L as CaCO3) + Noncarbonate hardness (mg/L as CaCO3))

In this case, the alkalinity = 284 mg/L as CaCO3 and the bicarbonate = 0 mg/L as CaCO3, so the carbonate hardness = 284 - 0 = 284 mg/L as CaCO3

Calculate the noncarbonate hardness:

The noncarbonate hardness can be calculated using the equation:

Noncarbonate hardness (mg/L as CaCO3) = Total hardness (mg/L as CaCO3) - Carbonate hardness (mg/L as CaCO3)

In this case, the noncarbonate hardness = 284 - 284 = 0 mg/L as CaCO3

Convert the values to meq/L:

To convert the values to meq/L, use the following conversion factors:

1 mg/L as CaCO3 = 0.01 meq/L

1 mg/L as MgCO3 = 0.02 meq/L

In this case, the total, carbonate, and noncarbonate hardness in meq/L can be calculated as:

Total hardness (meq/L) = 284 × 0.01 = 2.84 meq/L

Carbonate hardness (meq/L) = 284 × 0.01 = 2.84 meq/L

Noncarbonate hardness (meq/L) = 0 * 0.01 = 0 meq/L

So, the total hardness = 2.84 meq/L, carbonate hardness = 2.84 meq/L, and noncarbonate hardness = 0 meq/L.

A gas has a pressure of 1.43 atm and occupies
a volume of 7.7 L. If the gas is compressed to
a volume of 1.64 L, what will its pressure be,
assuming constant temperature?

Answers

The gas pressure after compression will be 6.76 atm.

What is gas pressure?The ideal gas law, one that states , PV = nRT, where P seems to be the pressure, V is the volume, n represents the number of moles of gas, R is the ideal gas constant, and T is the temperature in kelvin, can be used to calculate the pressure of a gas.

Assuming that number of moles of gas as well as the temperature remain constant during compression, the gas pressure after compression can be calculated as follows:

Given

Pressure = 1.43 atm

Volume = 7.7 L

Volume after compression = 1.64 L

V2 = (nRT) / 1.64 L P2 = (nRT)

P2 denotes the pressure after compression, and V2 denotes the volume after compression. To find P2, we must enter the following values into the equation:

6.76 atm = (1.43 atm x 7.7 L) / 1.64 L

As a result, the gas pressure after compression will be 6.76 atm.

9) The neutralization of a strong acid and strong base has an enthalpy change, ∆H°, = -55.9 kJ/mol. The net ionic equation for this reaction is
H⁺(aq) + OH⁻(aq) ⇌ H₂O(l)
which is the reverse of the autoionization of water, and therefore its equilibrium constant, K = 1.0 × 10¹⁴ at 25 °C. You can determine ∆S° from this data. Use the ∆H° and ∆S° values to calculate ∆G° at 70 °C. Assume ∆H° and ∆S° are temperature independent.

Answers

Answer:

For the equilibrium A+B⇌C+D, the entropy change is determined by ∆S° = -R lnK, where R is the gas constant and K is the equilibrium constant. Therefore, ∆S° = -R ln1.51 × 10⁻² = -8.37 J/K.

For the neutralization of a strong acid and strong base, ∆S° = -R lnK = -R ln1.0 × 10¹⁴ = -137.1 J/K.

The enthalpy change is ∆H° = -55.9 kJ/mol. Using this data, ∆G° at 70 °C can be determined by ∆G° = ∆H° - (T x ∆S°), where T is the temperature in Kelvin. Therefore, ∆G° = -55.9 kJ/mol - (343.15 K x (-137.1 J/K)) = -37.4 kJ/mol.

What is the change of the bar's length if the temperature is raised to 12.2 ∘C∘C above room temperature?

Answers

The change of the bar's length is ΔL =0. 000312 m if the temperature is raised to 12.2 ∘C∘C above room temperature.

Given that

At  room temperature ( T = 25 ∘C)  ,L= 1 m

L=1+2.4 X 10-5T

So the length at  13.0 ∘C above room temperature:

L=1+2.4 X 10-5T

L=1+2.4 X 10-5x13

L=1.000312 m

So the change in length

ΔL = 1.000312 - 1.0000 m

ΔL =0. 000312  m

Since the length of the aluminum bar, L is given by , L = 1.0000 + 2.4 × 10⁻⁵T and T = 14.1°C, we substitute the value of T into L. So, we have L = 1.0000 + 2.4 × 10⁻⁵ × 14.1°C = 1.0000 + 0.0003384 = 1.0003384 m. The change in length is thus 1.0003384 - 1.0000 = 0.0003384 m ≅ 0.00034 m.

Answers

Answer:

It's due to the forces that are known as balanced forces and it might also be because there is no friction

Answer:

The forces between you and the rock are balanced.

Explanation:

The force of your push against the rock and the opposing force of the rock pushing back on you are equal and opposite, meaning they balance each other out. This results in the rock not moving, because the net force on the rock is zero. This situation is referred to as static friction, which acts to prevent an object from moving when there is a force being applied to it. The force of static friction is always equal in magnitude but opposite in direction to the force being applied, until the force becomes large enough to overcome the static friction and cause the object to start moving.

a student dilutes 50.0 ml of a 0.10 mol/l solution of hcl to 0.010 mol/l by adding water. b. the total amount of solute decreases.

The total amount of solute decreases.

To calculate this, first, find the molarity of the original solution, which is 0.10 mol/l.

Then, use the dilution equation, M1V1 = M2V2,

to find the new volume (V2) of the diluted solution.

Plugging in the known values, V2 = V1 x (M2/M1) = 50.0 ml x (0.010 mol/l/0.10 mol/l) = 5.0 ml.

Since the total amount of solute (M1V1) stays the same (0.10 mol/l x 50.0 ml = 0.5 mol),

the volume of the solution (V2) decreases, the total amount of solute decreases.

What volume in quarts is occupied by 100g of Hg?

Answers

The volume of a substance is found to be measured in Liters, Milliliters, cubic meters, etc. The volume in quarts is occupied by 100g of Hg is 0.0077.

What is volume?

The term volume of a substance denotes how much capacity of matter it can hold. For example if a beaker can hold 100 mL of water, then its volume is said to be 100 mL.

The volume is also known as the ratio of mass to the density.

The equation connecting density and mass of a substance is given as:

Density (d) = Mass / Volume

Here density of Hg = 13.6 g cm⁻³, Mass = 100 g

Then d = 100 g / 13.6 = 7.352 cm³

1 cm³ = 0.001 L

V = 7.352 × 0.001 = 0.00735 L

1 L = 1.057 Quartz

0.00735 L = 0.0077 quartz.

Thus the volume in quarts is 0.0077.

Enzyme molecules are affected by changes in conditions within organisms. Explain how a prolonged, excessively high body temperature during an illness could be fatal to humans. Your answer must include:
the role of enzymes in a human
the effect of this high body temperature on enzyme activity
the reason this high body temperature can result in death

Answers

Enzymes are specialized proteins which can speed the reactions to a very great extent and thereby acts as efficient catalysts. The enzyme activity depends on pH and temperature.

What are enzymes?

The biological catalysts which catalyze the chemical reactions taking place inside the cells and are capable of acting independently on the cells are defined as the enzymes.

Enzymes catalyze and control several chemical reactions that occur in our living cells. They helps in digestion, liver function, breathing, reproduction, nerve function, etc. The enzyme urea catalyzes the hydrolysis of urea.

The enzyme activity is sensitive to the temperature changes. All the enzymes shows maximum catalytic activity at optimum temperature. They are found to be denatured by heat and hence their activity is destroyed at high temperatures.

Thus at high temperature the enzymes will be inactive and this will affect the vital organs and lead to death.
