What mistake did Carl make?

Answer:
The correct answer is:
'He did not multiply the chlorine and oxygen atoms by the coefficient 4'.
Explanation:
Number of atoms in
The 4 in front of molecular formula of calcium chlorate is its coefficient . it tells us about the molecules or moles of compound.
Number of calcium in 1 molecule of calcium chlorate = 1
Calcium atoms in 4 molecule of calcium chlorate = 1 × 4 = 4
Number of calcium in 1 molecule of calcium chlorate = 2
Chlorine atoms in 4 molecule of calcium chlorate = 2 × 4 = 8
Number of oxygen in 1 molecule of calcium chlorate = 3 × 2 = 6
Oxygen atoms in 4 molecule of calcium chlorate = 6 × 4 = 24
So, number of atoms of different elements calculated by Carl was wrong as he didn't multiplied the coefficient 4 with chlorine and oxygen atoms.

Answer:
time period is increased so the clock will become SLOW
Explanation:
As we know that the time period of the simple pendulum is given by the formula
here we know that
L = distance of the pendulum bob from the hinge
g = acceleration due to gravity
now here the bob slide down so that the length of the pendulum is being increased
so time period T of the pendulum is also increased
so here the pendulum will take more time to oscillate or to complete one oscillation
so clock will become SLOW
