Answer:
Example that involves phase change in which heat energy is released by substance:
Explanation:
If heat is removed from a substance, such as in freezing and condensation, then the process is exothermic. In this instance, heat is decreasing the speed of the molecules causing them move slower (examples: liquid to solid; gas to liquid). These changes release heat to the surroundings.3 days ago
Solid → Liquid: Melting or fusion
Gas → Liquid: Condensation
Liquid → Gas: Vaporization
Liquid → Solid: Freezing
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.

Explanation:
Answer:
cellular respiration
Explanation:
All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.
Aerobic respiration (oxidative phosphorylation)
- Use molecular O2.
- It degrades glucose to CO2 and H2O
- Exergonic
- Recovers about 50% of chemical energy
- Present in most organisms.
- It uses enzymes located in the mitochondria.
The non living things to help it survive would be the sun,water, and soil so that's is the answer
