Given the balanced equation representing a reaction:

sleet_krkn [62]

4Al(s) + 3O2(g) --> 2Al2O3(s) This is the balanced.
From the equation:

4 moles of Al required 3 moles of O2 to produce 2 moles of Al2O3

3 moles of O2 reacted with 4 moles of Al to produce 2 moles of Al2O3
1 mole of O2 reacted with 4/3 moles of Al to produce 2/3 moles of Al2O3 (Divide by 3)
4.5 moles of O2 reacted with (4/3 *4.5) moles of Al to produce (2/3*4.5) moles of Al2O3

4.5 moles of O2 reacted with 6moles of Al to produce 3moles of Al2O3

(3) is the answer. 6 mol of Al.

Oksanka [162]

Answer:

$\boxed {\boxed {\sf Hepta}}$

Explanation:

We are given the formula:

$PCl_5$

This is a molecular formula, because it contains nonmetals.

1. Name the first element

The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix.

Phosphorous

2. Second element

The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of <u>hepta</u>-.

Phosphorous heptachlorine

Add the ending of -ide.

Phosphorous heptachloride

The prefix used for the second element is hepta. The compound name is phosphorous heptachloride.
