Answer:
electrical
Explanation:
they are working together
Answer:
The more polar bond is C-O.
Explanation:
The greater polarity is due to that the Oxygen atom is more electronegative than the Nitrogen atom, so the negativity of the molecule tends to be on that side.
Answer:
Double replacement
Explanation:
The given reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
while,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Nitrogen gas consists of a diatomic nitrogen atom. So, the correct answer is B.
