Write a balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air.

Lelechka [254]

Answer: The balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is $CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O$ .

Explanation:

When a substance tends to gain oxygen atom in a chemical reaction and loses hydrogen atom then it is called oxidation reaction.

For example, chemical equation for oxidation of methane is as follows.

$CH_{4} + O_{2} \rightarrow CO_{2} + H_{2}O$

Number of atoms present on reactant side are as follows.

C = 1
H = 4
O = 2

Number of atoms present on product side are as follows.

C = 1
H = 2
O = 3

To balance this equation, multiply $O_{2}$ by 2 on reactant side. Also, multiply $H_{2}O$ by 2 on product side. Hence, the equation can be rewritten as follows.

$CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O$

Now, the number of atoms present on reactant side are as follows.

C = 1
H = 4
O = 4

Number of atoms present on product side are as follows.

C = 1
H = 4
O = 4

Since, the atoms present on both reactant and product side are equal. Therefore, this equation is now balanced.

Thus, we can conclude that balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is $CH_{4} + 2O_{2} \rightarrow CO_{2} + 2H_{2}O$ .

Calculate the mass of chlorine in a 20g tablet of calcium hypochlorite

Kobotan [32]

Answer:

9.92 g of Cl

Explanation:

Well first find out the molar mass of calcium hypochlorite.

The molecular formula is,

CaO₂Cl₂

Adding the atomic masses we get the molar mass = 142.98 g/mol

This means,

142.98 f of CaO₂Cl₂ = 70.91 g of Cl

Therefore,

20 g of CaO₂Cl₂ = X

Solving for X,

X = (70.91 g of Cl × 20 g of CaO₂Cl₂) ÷ 142.98 f of CaO₂Cl₂

X = 9.92 g of Cl

1. How many grams of Mg(OH)2 are there in 4.5 moles?

Ket [755]

Answer:

1) 262 grams

Explanation:

Mg = 24.305g

O = 16g

H = 1

24.305 +2(16)+2(1) = 58.305 g

× $\frac{58.305g}{1} = \frac{x }{4.5 } =262.37 g$
