Answer: The correct answer is C.
Explanation: Frictional force is the contact force which resists the motion of one surface on another.
Mathematically,
where,
f = frictional force
= Coefficient of friction
N = normal force acting on a body
We need to find the ratio of force of sliding friction ( which is a type of frictional force) and the normal force acting on an object. This will be equal to coefficient of friction.
CH₃-CH(-CH₃)-CH(-CH₃)-CH₃
2,3-dimethyl-1-butane
Explanation:
We have the following chemical reaction:
CH₂=C(-CH₃)-CH(-CH₃)-CH₃ + H₂ → CH₃-CH(-CH₃)-CH(-CH₃)-CH₃
So 2,3-dimethyl-1-butene will react with hydrogen to produce 2,3-dimethyl-1-butane.

Answer:
1610.7 g is the weigh for 4.64×10²⁴ atoms of Bi
Explanation:
Let's do the required conversions:
1 mol of atoms has 6.02×10²³ atoms
Bi → 1 mol of bismuth weighs 208.98 grams
Let's do the rules of three:
6.02×10²³ atoms are the amount of 1 mol of Bi
4.64×10²⁴ atoms are contained in (4.64×10²⁴ . 1) /6.02×10²³ = 7.71 moles
1 mol of Bi weighs 208.98 g
7.71 moles of Bi must weigh (7.71 . 208.98 ) /1 = 1610.7 g
