Answer: Option A: HCO3-(aq.)
Reason:
From the reaction, it can be seen that following reaction occurs in forward direct
HCO3-(aq) + H2O(l) → H2CO3(aq) + OH-(aq)
In above forward reaction, HCO3- accepts proton from H2O to generate H2CO3. Thus, according to Lowry and Bronsted theory of acid-base,
HCO3- is a base, while
H2CO3 is a conjugate acid.
Answer:
How the relative density of a substance is related to the density calculate the density of iron if its relative density is 2 and a density of water is 2gcm -3
R.d= relative density of substance/ relative density of water
R.d= 2/2
R.d= 1gcm-3
Explanation:
Nuclear fusion involves the combination of two light nuclei to form a heavier nucleus with emission of energy.
A nuclear reaction equation is a representation of the change that takes place as one nucleus is converted to another. A nuclear transformation could be any of the following;
- Nuclear fission
- Nuclear fusion
- Transmutation
We can know that a nuclear fusion is taking place when two nuclei come together to form a larger nucleus and emit energy. I would identify a nuclear fusion when;
- Two light atom combine to give a larger nucleus
- Tremendous energy is produced
