Answer:
Explanation:
Given that:-
Moles of K = 1.10 moles
Moles of Te = 0.55 moles
Moles of O = 1.65 moles
Taking the simplest ratio of the moles of the elements as:-
K : Te : O
1.10 : 0.55 : 1.65
2 : 1 : 3
Empirical formulas is the simplest or reduced ratio of the elements in the compound. So, the empirical formula is:-
1.8 g
<h3>Further explanation</h3><u>Given:</u>
0.80 g of methane reacts with 3.2 g of oxygen to produce 2.2 g of carbon dioxide.
<u>Question:</u>
What mass of water is formed?
<u>The Process:</u>
Methane and oxygen react to form carbon dioxide and water. Remember this, the chemical activity that uses oxygen to produce light and heat is also called the combustion process.
In any chemical reaction, the sum of the masses of the reactants is equal to the sum of the masses of the products. That's right, this is called conservation of the masses.
Let us write the word equation of the chemical reaction and then solve the problem following the law of the conservation of mass.
Rewrite by rearranging as follows:
Thus the mass of water formed is 1.8 g.
The balanced equation with state symbols is:
<u>Notes:</u>
- The French scientist Antoine Laurent Lavoisier represented his essential contribution by declaring the law of conservation of mass as one of the fundamental laws in chemistry.
- The law of the conservation of the mass states that in a chemical reaction the sum of the masses of the reactants is equal to the sum of the masses of the products.
