Answer:
Compounds are pure substance consisting of two or more different atoms
Answer: enzymes.
Explanation:
Microbial products are products derived from microorganisms. They may be primary or secondary metabolites. They are known to be environment friendly since they have biological origin. They are often degraded by enzymes which are also biological molecules. Degradation of materials using enzymes typically generates nontoxic products.
Answer: option 2
Explanation: each nitrogen is reduced from zero to -3 and Each H is Oxidised from 0 to +1
Since oxidation no of Nitrogen in molecular N2 is always zero and for H2 also zero.
In NH3, x+3(+1)=0
X+3=0
X=-3
And and hydrogen shows +1 Oxidation no when it is combined with non metal(like N,O,cl) and with -2 with metal like Na,Ca etc.
And zero in molecular form H2.
Neon-22 is the isotope with the greater mass.
P.S. When you have two isotopes of the same element, the one with the greater number will always have the greater mass
Hope that helps!
