Endothermic reaction

Heat is absorbed from the beaker by the reactants and the transfer of heat causes a temperature drop.

Hope this is the right answer!!!

Answer : This is an endothermic reaction.

Explanation :

Endothermic reaction : When the system absorb heat from the surrounding then the surrounding become cool.

Exothermic reaction : when the system releases heat into the surrounding then the surrounding become hot.

So, when ammonium chloride is dissolved in water then the beaker gets cold. That means the system is absorbing heat from the surrounding and thus the reaction is an endothermic reaction.

I’ve been up all night doin chemistry, can someone please give me the answers

m_a_m_a [10]

Here are your answers:

1. MgBr2 + Cl2 = MgCl2 + Br2

Balancing,
Already balanced.

Type of reaction: single displacement

2. Al + Fe2O3 = Al2O3 + Fe

Balancing,
2Al + Fe2O3 = Al2O3 + 2Fe

Type: single displacement reaction

3. AgNO3 + ZnCl2 = AgCl + N2O6Zn

Balancing,
2AgNO3 + ZnCl2 = 2AgCl + N2O6Zn

Type: double displacement reaction

MnO2
4. H2O2 ====== O2 + H20 [being catalyzed by manganese dioxide]

Balancing,
MnO2
2H2O2 ====== O2 + 2H2O

Type: decomposition reaction

5. Zn + HCl = ZnCl2 + H2

Balancing,
Zn + 2HCl = ZnCl2 + H2

Type: single displacement reaction

6. H2SO4 + NaOH = Na2SO4 + H2O

Balancing,
H2SO4 + 2NaOH = Na2SO4 + 2H2O

Type: Acid-base reaction

That took hella long!!! Hope it helps.
