Q4. 2H₂ + O₂ ⟶ 2H₂O; 5; 2

Q5. 24; 30; H₂; 0; 5

Explanation:

Q4.

The equation for the reaction is

2H₂ + O₂ ⟶ 2H₂O

One O₂ molecule reacts with 2H₂ molecules.

We started with seven oxygen molecules. Five of them reacted, so

Two O₂ molecules did not react.

Q5.

Two water molecules form from two hydrogen molecules.

Two water molecules form from one oxygen molecule

Hydrogen forms fewer water molecules of water, so

Hydrogen is the limiting reactant.

The 24 hydrogen molecules will be completely used up.

The number of hydrogen molecules remaining at the end of the reaction is zero.

They have reacted with 12 O₂ molecules.

The number of O₂ molecules remaining is 17 - 12 = 5

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
