Answer: The most abundant gas in the atmosphere is nitrogen.
Explanation:
The Earth’s atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, 1 percent argon and trace amounts of other gases that include carbon dioxide and neon.
Ph 4=100 ions
Ph5=10.0 or 1,000
Each Ph unit has 10 times as many hydrogen ions as the unit above it.
<span>Weight of CaC2 is 1.53 g
Temparature is 23 celcius T = 23 + 273K = 296K
The pressure of the gas P = 755 torr
Calculating the moles of CaC2 n = 1.53g x 64.0994 mol/g = 0.023869 moles
PV = nRT
V = nRT / P => V = (0.023869 mol) x (62.3636 L Torr / K mol) x (296 K) / 755 torr
Volume of C2H2 = 0.587 L</span>
Metal pots are good for cooking because they have heat conductivity.
