The correct answer is Ca(CIO3)2 i believe
Answer:
The process of breaking down stones or rocks into small pieces is called weathering.
Explanation:
Answer:21 moles of PbCl2 formed
Explanation: 3Pb(NO3)2(aq) + 2AlCl3(aq) --> 3PbCl2(s) + 2Al(NO3)3(aq)
14 moles AlCl3 x 3 moles PbCl2/2 moles AlCl3 =21 moles of PbCl2 formed
The answer is 4 Newton
force = mass x acceleration
F= 2 kg x 2.0 <span>m<span>s2</span></span>
= 4 Newton
Answer:
The solution turns purple because ammonia is a base.
The solution turned red.
Ammonia gas is neutral, but ammonia solution ( ammonium hydroxide ) is a base.
Adding vinegar to ammonia suppresses its dissociation hence decrease in hydroxyl ion concentration.
If more ammonia is added to the solution, the pink color re-appears.
