<span>a. If the actual mass of Magnesium used was larger then the measured and the amount of gas produced should be greater
b. when gas was cooler than its surroundings its density would be greater and the volume would appear to be smaller. This is because the gas molecules are very active and when heated they will expand.
</span>so they both bound increase the calculated moles of gas collected in the experiment

Describe the main difference between the Bohr model and the electron cloud model of the atom
Leno4ka [110]

Answer:

The main difference between the two models is <em>the position of the electron in the atom</em>.
