The reaction CO₂(g) → C(s) +O₂(g) is a decomposition reaction is true
Explanation
A Decomposition reaction is a reaction in which involve breaking down a compound into two or more simpler substances.
The reaction above is a decomposition reaction since CO₂ molecule is broken down into C (an element) and O₂ (a molecule).
Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
I believe it has something to do with the H2O molecules, because a chemical compound is not a mixture.
Answer:
Molarity = 0.13M
Explanation:
n=m/M = 4.87/74.55= 0.065mol, V= 500ml= 0.5dm3
Applying
n= C×V
0.065= C×0.5
C= 0.13M
