Answer:
Molar Mass of Calcium Carbonate = 100g
given mass = 50g
Number of mole of Calcium Carbonate =50/100 = 0.5 mole
Molarity = mole per litre of volume
Molarity = 0.5 /0.25 = 2mole/litre

Answer:
Combination reaction or synthesis reaction
Explanation:
Given reaction:
CO + H₂O → H₂CO₃
The type of reaction shown above is a combination or synthesis reaction. A combination reaction is one in which a single product is formed from two or more reactants.
In the given reaction carbon monoxide combines with water to produce hydrogen carbonate.
The formation of compounds from the union of their constituent elements falls into this category of reactions.
The answer is (2) CO and NH3. The chemical reaction can only break down chemical bonds between atoms inside the molecule. The He and Xe is consists of one atom only, so they can not be broken down by chemical means.
A(C)+A(F)+A(Br)+A(O)=12.01+19.00+79.90+16.00=126.91
n=381.01/126.91= 3
