1. Given the following reaction: 8CaO + Sg - 8CaS + 402
How many grams of molecular sulfur are needed to produce 27.5 L of oxygen at STP?

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

personal, she chose to do it.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
