A sample of gas is 22.0 degrees celcius and 0.980 atm occupies a volume of 5.8 mL. When the volume of the sample is increased to 10.0 mL and the temperture is increased to 45.0 degrees celcius the pressure of the gas sample is 0.613 atm. True or false?

Write a hypothesis that answers the lesson question, “while observing a chemical reaction, how can you tell which reactant is limiting? ” hypothesis: if a substance is the limiting reactant, then . . because . .

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

How do you know when a chemical reaction has occurred
