Answer:
pour in hot water and It will disolve
Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
Answer:
evaporation
Explanation:
The process of evaporation is as a result of water absorbing energy from the sun.
The process is a phase change in which liquid water changes into gaseous form.
- The water in gaseous form is called vapor
- This water cools and condenses in the atmosphere as it loses the energy it has gained.
- For evaporation to take place, water must absorb energy from the sun or other heating bodies.
- This will then cause vaporization of the liquid water into a gaseous form.
