PLZZZ help asaap plzzz I give brainliest are the following reactions a SYNTHESIS, DECOMPOSITION, COMBUSTION, SINGLE REPLACEMENT or DOUBLE REPLACEMENT reactions? N2 (g) + 3 H2 (g)→ 2NH3 (l)

2 H2(g) + O2(g--> 2 H2O(g)

Synthesis

Explanation:

Two reactants are becoming one product, so it is a synthesis reaction.

Decomposition is the opposite, so when one molecule becomes simpler atoms.

Example: 2NaCl -> Cl2 + Na

Combustion is reaction with a product of water and carbon dioxide.

Example: CH4 + 2O2 -> CO2 + 2H2O

Single displacement is when one atom takes the place of the other.

Example: K + NaCl -> KCl +Na (where K took the place of Na)

Double displacement is like single displacement but it happens twice. Think of it like the atoms exchanging partners.  

Example: HCl +NaH -> NaCl + HOH

(i) N2(g)+3H2(g) -->2NH3(g) - When the equilibrium changes, the concentrations of all substances involved in the equilibrium must also change. For our equilibrium reaction: N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat

(ii) 2 H2(g) + O2(g) --> 2 H2O(g) - Synthesis Reaction

HENCE BOTH THE REACTIONS COULD BE CLASSIFIED AS SYNTHEYIC REACTION

PLEASE DO MARK MY ANSWER AS THE BRAINLIEST..

<HOPE IT HELPS>

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
