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)

Respuesta :

Answer:

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

Answer:

(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>
