The table compares some characteristics of two atoms.
Mademuasel [1]

Answer:

Explanation:

Atom X,

Neutron num = 4, Mass num = 7

Therefore, proton number = Mass num - Neutron num

                                           = 7 - 4

                                           = 3

Atom Y,

Neutron num = 5, Mass num = 9

Therefore, proton number = Mass num - Neutron num

                                           = 9 - 5

                                           = 4

1) False. Atom X belongs to group 3 while atom Y belongs to group 4

2) False. Atom X is in a column on the left of Atom Y

3) True. Atom X and atom Y belong to the same period two on the periodic table

4) Fasle. Atom X and Y are not isotopes because they do not have the same atomic number.

Isotopy is a phenomenon whereby atom of same element have same atomic number but different mass number

If the volume of a gas at 0.5 atm changes from 150 mL to 75 mL, what is the new pressure?
prisoha [69]

Answer:

<h2>1 atm</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we're finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

We have

P_2 =  \frac{0.5 \times 150}{75}  =  \frac{75}{75}  = 1 \\

We have the final answer as

<h3>1 atm</h3>

Hope this helps you
