Answer:

Explanation:

1 = The given chemical reaction does not follow the law of conservation of mass because,

2 = Four hydrogen atoms are present in reactant side and two hydrogen atoms are present in product side.

3 = 1 ) The given chemical reaction does not follow the law of conservation of mass because,

CH₄ + O₂ → CO₂ + H₂O

16 g + 32 g 44 g + 18 g

48 g 62 g

Law of conservation of mass:

This law stated that mass can not be created or destroyed in chemical reaction. It just changed from one to another form.

For example:

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

28 g + 96 g = 88 g + 36 g

124 g = 124 g

18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the

MAXImum [283]

<u>Answer:</u> The chemical reaction for the synthesis reaction is given below.

<u>Explanation:</u>

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:

$A+B\rightarrow AB$

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

$2Ca(s)+O_2(g)\rightarrow 2CaO(s)$

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.
