Answer:

Explanation:

Molar mass of FeCl3 = 162.2 g/mol

1 mole FeCl3 -------------- 162.2 g

mole FeCl3 ---------------- 1.1 g

moles = 1.1 / 162.2

= 0.00678 moles

Consider the balanced chemical equation that follows. You are asked to determine how many moles of water you can form from 4 mol

kodGreya [7K]

Answer: The correct answer is $4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O$

Explanation:

We are given:

Moles of hydrogen gas = 4 moles

As, oxygen is given in excess. Thus, is considered as an excess reagent and hydrogen is considered as a limiting reagent because it limits the formation of products.

For the given chemical equation:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

By Stoichiometry of the reaction:

2 moles of hydrogen produces 2 moles of water molecule.

So, 4 moles of hydrogen will produce = $\frac{2molH_2O}{2molH_2}\times 4molH_2=4mol$ of water.

Hence, the correct answer is $4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O$

What is a characteristic of every combination reaction?

Scilla [17]

A combination reaction is a reaction in which two reactants combine to form one product. It is also called a synthesis reaction. A characteristic to this type of reaction would be that there would always be only one product. Hope this answers the question. Have a nice day.
