NaHCO₃ + HCl → NaCl + H₂O + CO₂
<u>Explanation:</u>
NaHCO₃ + HCl → NaCl + H₂O + CO₂
When Sodium bi carbonate (NaHCO₃) reacts with hydrochloric acid (HCl), it forms table salt (NaCl), water ( H₂O ) and Carbon di oxide (CO₂) gas is evolved.
Here base reacts with acid to form salt and it is the neutralization reaction.
The atomic number actually represents the number of
electrons in the atom. So when the atomic number is 24 and the actual number of
electron is only 22, so this means that there is a deficit of 2 electrons.
Hence the charge must be positive 2.
Answer:
2+
Letter D is the only option which includes animals from both land and ocean habitats. I believe this one is the answer.
Argon has 24 known isotopes.
It is a molecule of the compound.
