Answer : The mass percentage of hydrogen in hexanal is, 12 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

First we have to calculate the molar mass of hexanal.

Molar mass of hexanal (C_{6}H_{12}O) = 6(12)+12(1)+(16)=100g/mole

Now we have to calculate the mass of carbon.

As we now that there are 6 number of carbon atoms, 12 number of hydrogen atoms and 1 number of oxygen atoms.

The mass of hydrogen = 12\times 1=12g

Now we have to calculate the mass percentage of hydrogen in hexanal.

Formula used :

\%\text{ Mass percentage of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of hexanal}}\times 100

Now put all the given values in this formula, we get:

\%\text{ Mass percentage of hydrogen}=\frac{12}{100}\times 100=12\%

Therefore, the mass percentage of hydrogen in hexanal is, 12 %

Mg(OH)2+2 HCI = MgCI2+ H2O
In-s [12.5K]

Answer:

Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O

Explanation:

In order to balance a chemical equation you need to make sure both sides of the equations are equal.

Mg(OH)2 + 2HCI = MgCI2 + H2O

Mg = 1

Oh = 2

HCI = 2

Products:

Mg = 1

CI = 2

H = 2

O = 1

2H20 = 1 × 2 = 2

2 × 2 = 4

2HCI

1 × 2 = 2

Mg(OH)2 + 2HCI ⇒ MgCI2 + 2H2O

Hope this helps.
