What are the isotopes? how all of the isotopes of an atom are similar and how are they different?

madam [21]

Isotopes are the same element with a different mass number. They are similar because once again the protons are equal to the atomic number which keeps the identity of the atom the same. But they are different because the masses of each is different.

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 $4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O$
