19. The atomic number is the same as protons and electrons unless it have a - or a + charge the electrons are going to change
<u>Answer:</u> The final volume of the gas comes out to be 4 L.
<u>Explanation:</u>
To calculate the volume with changing pressure, we use the equation given by Boyle's law.
This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
We are given:

Putting values in above equation, we get:

Hence, the final volume of the gas will be 4 L.
Answer:
32.25
Explanation:
8NH3 + 3Cl2 → 6NH4Cl + N2
NH3 = 17 g/mol
number of moles = 1
NH4Cl= 43 g/mol
number of moles = 3/4
mass= 43 × ¾ ≈ 32.25 g
False, because heat travels from warm to cool objects, so if both have the same temp ( ie: no temp difference) heat will not be transferred between them.

760 mmHg = 1 atm Therefore 30 atm = 760 * 3 mmHg = 2280 mmHg p1 = 700 mmHg p2 = 2280 mmHg You can compare them from there. You may also convert mmHg to atm by dividing by 760.
Your answer would be 243.2 mm Hg
