Answer:
copper(ll) carbonate
Explanation:
Since the product is a salt which is copper(II) carbonate, water and carbon dioxide, this reaction is an acid + metal carbonate reaction.
Looking at the salt, Cu²⁺ has to be part of the reactants.
Hence, the missing compound there has to be copper(ll) carbonate, CuCO₃.
The balanced chemical equation would be:
CuCO₃ + 2HNO₃➙ Cu(NO₃)₂ +H₂O +CO₂
P.s. You left out CO₂ as a product in Q2 ;)
Just a recap of the main reactions you would've learnt:
1) Acid + base/ alkali ➙ salt + water
2) Acid + metal ➙ salt + hydrogen gas
3) Acid + metal carbonate ➙ salt + H₂O + CO₂

Answer:
Part A 
Kg
Part B 
meters
Explanation:
Part A
Pressure is equal to force per unit area
Here force is equal to the weight of the piston
Thus
On rearranging the equation, we get -
Substituting the given values we get
Part B
We know that
On substituting the given values we get -
Height
Answer:
the difference is the presence of a carbon atom
Explanation:
Answer:
D. The number of atoms present
Explanation:
In a balanced equation, coefficients always represent the number of atoms present.
