At STP, P = 1 atm, and T = 0 C
Thus, PV = nRT => V = nR(273). We will use this later...
if you have 35.4 Ca, and the molar mass of Ca is 40.08, you get .883 moles Ca. Thus, since it takes 2 moles of Ca to form a reaction, you only need half the moles of Ca of O2. Thus, n(O2) = .883/2
Tie this back to the first equation and you get
V = .442 * <span>0.082057(which is R) * 273 = 9.9 L</span>
No
Water’s density is 1 g/cm3 and AL is 2700kg/m3
Answer:the mass of the gases and ash should be equal the mass of the initial stack of newspapers, there are equal number of atoms on both sides
Explanation:no matter what form the newspaper would take the mass stays the same because all you did is burn it, conserve means that each atom's mass will stay the same no matter what.
