Determine if the moles of gas in the container increase, decrease, or remain constant as the reaction goes to completion

What happens to isotopes that are unstable?

1. if you have a gas at 127 degrees c, what is it's absolute temperature (kelvin)? a. 200kb. 300kc. 400kd. 500k2. if you had a gas whose absolute temperature measured 45 k, what is that temperature in celsius? a. -228 cb. -300 cc. 125 cd. 112 c

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
