Answer:

1. A. Zero.

2. D. Greater than zero, and greater than the rate of the reverse reaction.

3. C. Greater than zero, and equal to the rate of the reverse reaction.

4. A. Some, but less than 237. mmol.

Explanation:

Before reactants are added in a system the rate of reaction is zero. This is because, the initial rate of reaction depends on the concentration of the reacting species in the system.

When the reactants are first added, the rate of forward reaction increases rapidly and is far greater than the rate of reverse reaction.

However, at equilibrium, the rate of forward reaction is equal to the rate of reverse reaction.

At equilibrium, some NH3 has been used and some will still remain in the system because the reaction is reversible.

The response would become spontaneous if the value of ΔG° was negative.

According to the estimated value of ΔG°, it is shown that ΔG° value decreases as temperature value increases. The value shifts from being more favorable to being less favorable. It would appear that the value of ΔG° would be negative at a specific temperature, causing the reaction to occur spontaneously.

The reaction is in an equilibrium state if ΔG = 0. If ΔG < 0, the reaction is spontaneous in the direction written. The relationship between terms from the equilibrium is paralleled by the relevance of the sign of a change in the Gibbs free energy.

Stomach acid is approximately 0.10 M HCl. How many mL of stomach acid can be neutralized by one regular antacid tablet that cont

Radda [10]

Answer:

100 mL

Explanation:

The reaction that takes place is:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

First we convert 500 mg of CaCO₃ into mmoles, using its molar mass:

500 mg ÷ 100 mg/mmol = 5 mmol CaCO₃

Then we convert 5 mmoles of CaCO₃ into HCl mmoles, using the stoichiometric coefficients of the balanced reaction:

5 mmol CaCO₃ * $\frac{2mmolHCl}{1mmolCaCO_3}$ = 10 mmol HCl

Finally we calculate the volume of a 0.10 M HCl solution (such as stomach acid) that would contain 10 mmoles:

10 mmol / 0.10 M = 100 mL

A cylinder of oxygen gas contains 2.80 mol of 02. If the volume of the cylinder is 8.58 L, what is the pressure of the 02 if the

Anni [7]

Answer:

pressure of the oxygen gas is 7.88atm

Explanation:

Moles of oxygen in cylinder = 2.80 mol

volume=8.58L

temperature=294K

molar gas constant(R)= 0.0821 L atm / (mol K)

The pressure is calculated using ideal gas law:

PV = nRT

making Pressure subject of the formula

P = nRT /V

= 2.80× 0.0821 ×294 /8.58 L

P = 7.88 atm
