Answer:
See the answer below , please.
Explanation:
In a decomposition reaction, a certain compound is "broken" to give two or more different products.
An example for compound AB, giving as products A and B:
AB -> A + B
In the case of water:
2H20 -> 2H2 + 02, water decomposes giving Hydrogen and Oxygen
Explanation:
1) their is no formation of new substance
2) the reaction can be reverse i.e if we heat sugar solution it we give us sugar and water.

Answer:
increases
decreases
Explanation:
The distance between particles increases when the temperature increases and decreases when temperature decreases.
- Temperature changes in a system causes the particle of such system to behave in different ways.
- When particles gain heat energy as their temperature increases, they begin to move further apart.
- As their temperature reduces they tend to coalesce.
Answer:
The volume of the piece of iron is 5.18dL.
Explanation:
The density (ρ) is equal to the mass (m) divided the volume (V).

If we rearrange it, we have:

To express the volume in dL we will need the following relations:
- 1 dL = 0.1 L
- 1 kg = 10³ g
- 1 cm³ = 1 mL
- 1mL = 10⁻³L
Then,

Finally,
