GOOD LUCK FOR THE FUTURE! :)
Explanation:
It is claimed that the increases in crop productivity brought about by genetic engineering can help relieve problems faced by farmers by decreasing the losses caused by pests, disease, weeds, and other stressors (Guerinot 2000).
Answer:
The correct answer is option B, that is, CO + H2O → H2 + CO2
The redox reactions are regarded as the chemical reactions in which one reactant goes through the process of reduction and one reactant goes through the process of oxidation. The reduction reactions are the reactions in which gain of electrons occurs, while oxidation reactions are the reactions in which loss of electrons occurs.
From the mentioned options, only option B, that is, CO + H2O → H2 + CO2 is a kind of redox reaction. In this, the carbon is getting oxidized from +2 to +4 oxidation state, and hydrogen is getting reduced from +1 to 0 oxidation state. Hence, this reaction can be regarded as a redox reaction.
Explanation:
As we know, Number of protons = Atomic Number
So,
And, Atomic mass = Number of protons + Number of Neutrons (N)
therefore ~
Number of Neutrons = 19
