chemistry A basketball is inflated to a pressure of 1.10 atm in a 28.0°C garage. What is the pressure of the basketball outside

butalik [34]

Answer : The final pressure of the basketball is, 0.990 atm

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$

or,

$\frac{P_1}{P_2}=\frac{T_1}{T_2}$

where,

$P_1$ = initial pressure = 1.10 atm

$P_2$ = final pressure = ?

$T_1$ = initial temperature = $28.0^oC=273+28.0=301.0K$

$T_2$ = initial temperature = $-2.00^oC=273+(-2.00)=271.0K$

Now put all the given values in the above equation, we get:

$\frac{1.10atm}{P_2}=\frac{301.0K}{271.0K}$

$P_2=0.990atm$

Thus, the final pressure of the basketball is, 0.990 atm

What happens to a white light passes through a prism?

alexgriva [62]

When white light passes through a prism, the colour spectrum appears otherwise known as wavelengths. This is caused by the shape of the prism, due to the shape of the prism this bends the light and as a result the white light separates into wavelengths therefore showing colours depending on angle of light.

If 36 grams of aluminum react with an excess of oxygen, as shown in the balanced chemical equation below, how many grams of alum

Ludmilka [50]

Molar mass of Al = 26.98
molar mass of Al2O3 = 101.96
36 / 26.98 = 1.3343 moles Al
set up a proportion : 1.3343 / 4 = x / 2 (let x = moles of Al2O3)
x = 0.66716 moles of Al2O3
0.66716 * 101.96 = 69.024 g of Al2O3

An unfortunate squirrel is hit by a car. A small bit of gas originally 0.005 L in volume is trapped in the squirrel's body at a

kykrilka [37]

Answer: The volume of the gas in the squirrel now is 0.00532 L

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
