Answer:

THE PRESSURE OF THE TIRE ON THE TRIP HOME AT THE ROAD SURFACE TEMPERATURE OF 32°C IS 160 kPa.

Explanation:

Initial Pressure = 75 kPa

Initial temperature = 15 °C

Final temperature = 32 °C

Final pressure = unknown

Using the combined equation of gases;

P1V1/T1 = P2V2/ T2

Since the tire will have the same volume of air in it showing that volume of constant both at the repair shop and on the road surface.

The relationship between pressure and temperature is used with constant volume.

P1/T1 = P2/ T2

75 kPa / 15 °C = P2 / 32 °C

P2 = 75 kPa * 32 °C / 15 °C

P2 = 2400 kPa °C / 15 °C

P2 = 160 kPa.

So therefore, the pressure of the tire on the trip home when the temperature of the road surface is 32°C is 160 kPa.

What is the total number of moles of atoms in one mole of (NH4)2SO4? 1. 10 2. 11 3. 14 4. 15
Neporo4naja [7]

Answer:

4. 15

Explanation:

The given formula is:- (NH_4)_2SO_4

1 mole of the salt contains 2 moles of nitrogen atom, 8 moles of hydrogen, 1 mole of sulfur and 4 moles of oxygen atom as can be seen from the formula.

Thus,

1 mole of salt contains total of 15 moles of the atoms which constitute the salt.

<u>Hence, 4. is the answer.</u>
