Answer:

Absorbs energy

Explanation:

As an electron in an atom moves from the ground state to the excited state, the electron absorbs energy.

Electrons moves around in permissible orbits around the nucleus of an atom.

  • An electron in a certain energy level has a definite amount of energy associated with it at that level.
  • When an electron in ground state absorbs energy, it moves to a higher energy level.
  • When an electron in excited state loses energy, it moves to a lower energy level.

The transition of electrons from one level to another involves loss or gain of energy.

C(S)+O2(g)-->CO2(g)
soldi70 [24.7K]

<u>Answer:</u> The correct answer is 1.18 g.

<u>Explanation:</u>

We are given a chemical equation:

C(S)+O2(g)\rightarrow CO_2(g)

We know that at STP conditions:

22.4L of volume is occupied by 1 mole of a gas.

So, 2.21L of carbon dioxide is occupied by = \frac{1}{22.4L}\times 2.21L=0.0986mol of carbon dioxide gas.

By Stoichiometry of the above reaction:

1 mole of carbon dioxide gas is produced by 1 mole of carbon

So, 0.0986 moles of carbon dioxide is produced by = \frac{1}{1}\times 0.0986=0.0986mol of carbon.

Now, to calculate the mass of carbon, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Moles of carbon = 0.0986 mol

Molar mass of carbon = 12 g/mol

Putting values in above equation, we get:

0.0986mol=\frac{\text{Mass of carbon}}{12g/mol}\\\\\text{Mass of carbon}=1.18g

Hence, the correct answer is 1.18 g.

Which of the following sets of units could be appropriate for a zero-order rate constant?Answers-1L mol-1 s-1L2 mol-2 s-1L3 mol-
mars1129 [50]

Answer:

mol·L⁻¹·s⁻¹

Explanation:

In the case of a <em>zero-order reaction</em>, the reaction rate does not change with the decrease or increase in the concentrations of the reactants:

  • rate = k

And because the rate must have units of mol·L⁻¹·s⁻¹, then the rate constant <em>k</em> must also have units of mol·L⁻¹·s⁻¹.
