Rhea has a balloon that contains 0.5 mole of helium. how many particles of helium are in the balloon?
horrorfan [7]

Answer:

\boxed{3 \times 10^{23}}

Explanation:

1 mol of helium contains 6.022 × 10²³ atoms

\text{Atoms of He} =\text{0.5 mol He} \times \dfrac{ 6.022 \times 10^{23} \text{ atoms He}}{\text{1 mol He}}= 3 \times 10^{23} \text{ atoms He}

The balloon contains \boxed{3 \times 10^{23} \text{ atoms of He}}.

Which element(s) is/are not balanced in this equation?<br><br><br> Fe2O3 + 3 CO → Fe + 3 CO2
Gnom [1K]

<u>Given:</u>

Fe2O3 + 3CO → Fe + 3CO2

<u>To determine:</u>

The elements that are not balanced in the above equation

<u>Explanation:</u>

A chemical equation is said to be balanced if the number of atoms on the reactants is equal to that of the product side.

Reactant                          Product

Fe = 2 atoms                   Fe = 1 atom

O = 6 atoms                    O = 6 atoms

C = 3 atoms                     C = 3 atoms

<u>Ans:</u> Therefore, Fe is not balanced as there is 1 atom less on the product side

Balanced equation:        Fe2O3 + 3CO → 2Fe + 3CO2
