Answer:

75mL

Explanation:

Data obtained from the question include:

C1 = 2M

V1 =?

C2 = 0.60M

V2 = 250mL

The original volume of solution can be obtained as follows:

C1V1 = C2V2

2 x V1 = 0.6 x 250

Divide both side by 2

V1 = (0.6 x 250) / 2

V1 = 75mL

The volume needed is 75mL

Which example involves phase change in which heat energy is released by the substance?
Komok [63]

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

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.

The pathway by which carbon is transferred from living organisms to the atmosphere is called:
Phoenix [80]

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.
