Question

QUESTION 17 How would you read the following chemical equation? N2(g) + 3H2(g) + 2NH3(g) Note: Some chemist might say diatomic nitrogen and diatomic hydrogen gas, to make that really clear. That would be a second correct way fo asking these questions 2 moles of nitrogen gas and 2 moles of hydrogen gas react to form 2 moles of nitrogen trihydride gas. . 1 mole of nitrogen gas and 3 moles of hydrogen gas react to form 2 moles of nitrogen trhydride gas 4. 1 mole of nitrogen gas and 1 mole of hydrogen gas react to form 1 mole of nitrogen trihydride gas. 1.2 moles of nitrogen gas and 6 moles of hydrogen gas react to form 2 moles of nitrogen gas and 6 moles of hydrogen gas.

Answer 1

How would you read the chemical reaction N2(g) + 3H₂(g) → 2NH₂ (9) is If more than one atom of particular element present, then it's indicated by number in Subscript after atomic symbol for example H₂O means 2 atoms of Hydrogen and one of oxygen and this combine to form a molecule. Combining 2 atoms or more atom forms a molecule, and the numbes of molecules ar moles formed denoted by number for example - 2 H2O = 2 mole of (water) Dihydrogen - and one oxygen gas - 1) The option A, D eliminated because in the reaction only one mole of N219) is there not a mole of Nag option also eliminated, because I mole of Nitrogen trihydride gas is not formed 2 mole of Nitrogen tringdride gas is formed option is B The corect s scared with CS CamScanner

we have to read the reaction as Imole of Nitrogen gas and 3 moles of hydrogen gas react to form 2 moles of nitrogen trihydride gas. CS Scanned with CamScanner

To read the chemical reaction we have to see number of atoms combined.

2 or more atoms combines and form the moles or molecules.

For example, Combinatio of 2 hydrogen atoms form one mole of Hydrogen.

And the term in brackets give the phase of molecules such as , g for gas , s for solid , l for liquid.

Like this we have to read the chemical reaction

In this question , option A, C ,D are eliminated.

Correct option is option B , which is

1 mole of Nitrogen gas and 3 moles of hydrogen gas react to form 2 moles of nitrogen trihydride gas.
