Question

Narrate how Mrs. Bouncer befools her tenats.​

Answer 1

In the first experiment:-

Weight of copper oxide, (CuO)=1.288g

Weight of copper =1.03g

Weight of oxygen = Wt. of copper oxide − Wt. of copper =1.288−1.03=0.258g

∴

Wt. of oxygen

Wt. of copper

=

0.258

1.03

≈

1

4

In the second expriment:-

Weight of copper oxide (CuO)=3.672g

Weight of copper =2.938g

Weight of oxygen = Wt. of copper oxide − Wt. of copper =3.672−2.938=0.734g

∴

Wt. of oxygen

Wt. of copper

=

0.734

2.938

≈

The proportion of elements of copper and oxygen in the reactions is same.

Hence law of constant proportion is proved.

She rented the same room of the apartment to both John Box and James Cox . Mrs. Bouncer knew that Box works at a newspaper office all night and Cox makes hats all day, so they will never run into each other. So she fooled both her tenants by taking double rent for a single room .
