Answer:
Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table. Carbon is a very abundant element. It exists in pure or nearly pure forms – such as diamonds and graphite – but can also combine with other elements to form molecules.
It is directly proportional
gimme a sec im doing the quick check.
Answer:
If the tilt of the Earth's axis is changed there would be a change in the season because the season is caused by the Earth's tilt (23.5 degrees) and the revolution or orbit.
First, we determine the number of moles of gas present using the ideal gas equation.
PV = nRT
n = PV / RT
n = (1.4 * 226.4) / (0.082 *(27 + 273.15))
n = 12.88
Next, we use the given percentages to find the moles of helium present
Moles of helium = 0.655 * 12.88
Moles of helium = 8.44
Next, we use the formula:
Mass = moles * molar mass
Mass of helium = 8.44 * 4
Mass of helium = 33.76 grams
