^ molecule of methane. CHi, consists of 4 kiydrogen atoms bonded to a central carbon alom Which of the following statements is true?
a.
b.
There are 18.02 g of methane in I mol of methane.
1 L of liquid methane has fewer moles of methane than 1 L of methane gas.
c.
There are 5* (6.022 x1023) molecules in 1 mol of methane.
d. There are approximately 6.022 * 105 'atoms oF C'and 4- (6.022 × 1023) atoms of H in 1
mol of methane.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
