Nuclear decay is the decay of atoms on the atomic scale. “Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.”
Explanation:
Carbon dioxide isn't a polar molecule because
same nature of charge appears in opposite direction which cancel each other. So, carbon dioxide is non-polar molecule.
Answer:
v₁ = 7.5mL
Explanation:
using the formula
m₁v₁=m₂v₂
given m₁=10x m₂=1x v₁=? v₂=75mL
10x × v₁ = 1x × 75mL
v₁ = 1x × 75mL / 10x
v₁ = 7.5mL
So, 7.5mL of 10x PBS should be added with 67.5mL of water
