Given the equation representing a system at equilibrium:N2(g) + 3H2(g)<==>2NH3(g) + energyWhich changes occur when the temperature of this system is decreased?
(1) The concentration of H2(g) increases and the concentration of N2(g) increases.
(2) The concentration of H2(g) decreases and the concentration of N2(g) increases.
(3) The concentration of H2(g) decreases and the concentration of NH3(g) decreases.
(4) The concentration of H2(g) decreases and the concentration of NH3(g) increases.

Answers

Answer 1
Answer:

When the temperature is decreased, the concentration of H2(g) decreases and the concentration of NH3(g) increases.

What is equilibrium?

The term equilibrium refers to the point when the rate of forward reaction is equal to the rate of reverse reaction. In that case, the reaction has attained a dynamic equilibrium.

Now, when the temperature is decreased, the concentration of H2(g) decreases and the concentration of NH3(g) increases.

Answer 2
Answer:

N2(g) + 3H2(g)<==>2NH3(g) + energy, the changes that occur when the temperature of this system is decreased is that concentration of H2(g) decreases and the concentration of NH3(g) increases. The answer is number 4. The rest of the choices do not answer the question above.

Each glucose molecule consists only of carbon, hydrogen, and oxygen atoms. If each molecule contains 53.3% oxygen and 6.7% hydrogen by mass, what percentage of each glucose molecule is made up of carbon?

Answers

53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.
