I believe the correct answer from the choices listed above is option D. When a gas is compressed in a cylinder the amount (mass) of gas remains unchanged. This is due to the law of conservation mass where mass cannot be created nor destroyed. In this case, it is the volume of the gas is changed not the mass.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 4al(s)+3o2(g)→2al2o3(s) a) 1 molal, 1 mol o2 b) 4 molal, 2.6 mol o2 c) 16 molal, 13 mol o2 d) 7.4 molal, 6.5 mol o2
