The answer is A. Has a low pH in solution.
Answer:
There will not be any ejection of photoelectrons
Explanation:
Energy of the photon= hc/λ
Where;
h= Plank's constant
c= speed of light
λ= wavelength of the incident photon
E= 6.6×10^-34 × 3 ×10^8/488 × 10^-9
E= 4.1 ×10^-19 J
Work function of the metal (Wo)= 2.9 eV × 1.6 × 10^-19 = 4.64 × 10^-19 J
There can only be ejected photoelectrons when E>Wo but in this case, E<Wo hence there will not be any ejection of photoelectrons.
Explanation:
The equation doesn't satisfy the Law of Conservation of Matter because There are more oxygen atoms after the reaction than there were before the reaction.
Therefore,
Option C is correct ✔
Answer:
Estuaries are often called the “nurseries of the sea”
Explanation:
Because so many marine animals reproduce and spend the early part of their lives there.
Answer: KCIO3
Explanation:
The graph shows that it is the lowest at 0 degrees meaning that it has the lowest solubility
