Answer:

The correct answer is:

'He did not multiply the chlorine and oxygen atoms by the coefficient 4'.

Explanation:

Number of atoms in $4 Ca(ClO_3)_2$

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.

A commuter train travels from New York to Washington, DC, and back in 6 hours and 5 minutes. The distance between the two statio

vovikov84 [41]

Answer:

The train's displacement is zero.

Explanation:

Given data,

The time taken by the train from NY to Washington and back is, t = 6 h 5 min

The distance between the two stations is, d = 363 km

Therefore, the total distance the train traveled is, d' = 726 km

The displacement is defined as the change in position coordinates with respect to its original position.

If the train travels from one point and returns back to the same point after some time, there is no change in the position coordinates with respect to its original position.

Hence, the train's displacement is zero.
