Answer:
B) X = NAD+ Y = NADH + H+
Explanation:
The reaction catalyzed is a redox, where the alcohol is oxidated to acetaldehyde and NAD+ is reduced to NADH+ + H+
Answer:
D. 25cm3
Explanation:
if you add a 3 at the end of a number it means volume, therefore making it a solid
Answer:
B. Add more water to decrease the concentration.
Explanation:
If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.
- Concentration is the amount of solute in a solution.
- Conductivity deals with the ability of a solution to allow the passage of current.
Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.
- Adding more water increases the amount of solvent and the concentration reduces.
Explanation:
Set up the ion formation equations, with ionization energy values for each electron in the valence layer, of the atoms of the chemical elements below: a) Na z=11 b) Ca z= 20 c) Sr z 38 d) Li z= 3 e) Cs z= 55 f) Be z= 43
Answer:
Using valence bond theory, HgCl2 is sp hybridized while PCl3 is sp3 hybridized.
Explanation:
sp hybridized molecules are largely covalent and cannot conduct electricity hence the nonconducting nature of HgCl2. PCl3 contains a lone pair and three unpaired electrons in sp3 hybridized orbitals.
