Answer:

Fourth Stroke.

Explanation:

There are four strokes in a car engine

a) Intake stroke: In this stroke the air and fuel is being pumped into the compressor from intake valve.

b) compression stroke: The piston moves upward and the fuel air mixture undergoes compression.

c)combustion stroke: The spark plug generates a spark and the fuel undergoes combustion. The energy produced push the piston backwards or downwards.

d) Exhaust stroke: the exhaust gases like carbon dioxide , water, carbon monoxide etc are forced up by the piston.

10. A sample of gas occupies 4.00 L at 80.0 kPa at 303 K. How many moles of gas are in the sample? If the sample weighs 20.50 gr

Lunna [17]

Answer:

Moles: $n=0.127mol$

Molar mass: $M=200.61 g/mol$

Explanation:

Hello,

In this case, we can use the ideal gas equation to compute the moles of the gas sample as shown below:

$PV=nRT\\\\n=\frac{PV}{RT}$

Thus, we should use the pressure in atm as follows:

$n=\frac{80.0kPa*\frac{0.00986923atm}{1kPa}*4.00L}{0.082\frac{atm*L}{mol*K}*303K}\\ \\n=0.127mol$

Moreover, the molar mass is obtained by dividing the given mass by the obtained moles:

$M=\frac{m}{n}=\frac{25.50g}{0.127mol}\\ \\M=200.61 g/mol$

Best regards.

Using full detail, describe the theory of plate tectonics.

yuradex [85]

Plate tectonics is a scientific theory that describes the large-scale motion of Earth's lithosphere. Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move.
