There are two equations given in the question. The type of reaction shown can be easily judged, if one takes a closer look at the equations.
1. <span>Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g) ------- Redox
2. </span><span>CaO(s) +CO2(g) ----> CaCO3(s) -------- None.
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>

it exists as atom or ion but not as sodium molecule. So there is no any sodium sodium bonding between two sodium atoms. Sodium combines with other element or group to form compounds of sodium like sodium chloride ,sodium carbonate ,sodium sulphate etc. Sodium has symbol Na and its atomic no. is 11 .
Answer:
<h2>10 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2 × 5
We have the final answer as
<h3>10 g</h3>
Hope this helps you
Answer:
Nitrifying bacterium such as nitrosomonas or nitrobacter, whe applied to the soil, convert free ammonia or nitrogen to nitrates through oxidation. They are a group of aerobic bacteria playing an important role in the nitrogen cycle as producers of energy from inorganic source.
The schematic diagram attached summaries the action of such bacteria.
