Two different compounds are formed by the elements nitrogen and oxygen. The first compound, compound P1, contains 64.17% by mass

xz_007 [3.2K]

Answer:

Explanation:

To solve the problem, we must know the kind of compounds we are dealing with.

For the first compound, P1 and second compound P2:

N O N O

Mass percent 64.17 35.73 47.23 52.79

Atomic mass 14 16 14 16

Number of

moles 64.17/14 35.73/16 47.23/14 52.79/16

4.58 2.23 3.37 3.30

Simplest

ratio 4.58/2.23 2.23/2.23 3.37/3.30 3.3/3.3

2 1 1 1

P1 compound is N₂O

P2 compound is NO

These are the compounds,

In N₂O = 28:16

NO = 14:16

This is the ratio of nitrogen to a fixed mass of oxygen for the two compounds.

How many grams of H20 are produced from the reaction of 30.0g of Mg(OH)2 reacting with

Anna35 [415]

<u>Answer:</u> The mass of water required is 18.52 g

<u>Explanation:</u>

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ ......(1)

Given mass of magnesium hydroxide = 30.0 g

Molar mass of magnesium hydroxide = 58.32 g/mol

Plugging values in equation 1:

$\text{Moles of magnesium hydroxide}=\frac{30.0g}{58.32g/mol}=0.5144 mol$

The given chemical equation follows:

$Mg(OH)_2+2HCl\rightarrow MgCl_2+2H_2O$

By the stoichiometry of the reaction:

If 1 mole of magnesium hydroxide produces 2 moles of water

So, 0.5144 moles of magnesium hydroxide will react with = $\frac{2}{1}\times 0.5144=1.0288mol$ of water

Molar mass of water = 18 g/mol

Plugging values in equation 1:

$\text{Mass of water}=(1.0288mol\times 18g/mol)=18.52g$

Hence, the mass of water required is 18.52 g
