Charle's law states that at constant pressure, absolute temperature and volume are proportional. Mathematically,
V ∝ T. T, the temperature, is quoted in Kelvins.
Explanation:
Given the proportionality, <span><span>V1</span><span>T1</span></span> = <span><span>V2</span><span>T2</span></span>. <span>V2</span> is unknown but <span>V2</span> = <span><span><span>T2</span>×<span>V1</span></span><span>T1</span></span>
Remember, that this assumes a constant pressure. Charles' law is also the reason that we can fly hot air balloons. The experiment has doubled the temperature, so how will volume evolve? Will it get bigger, smaller, remain the same?
Take the atomic mass in grams and the number of atoms in the sulfur molecule and multiply: so 8 x 32.065 grams = 256.52 grams. That iDVD the number of grams in one mole of sulfur. In each mole of anything there are Avogadro's number (6.022x10^23) of molecules.
Hope this helps
In ionic compounds, the metal is always the positively charged ion, and the nonmetal negatively charged. Therefore, the sodium ion is positively charged and the chloride ion is negatively charged.
Hope this helps!
