Because so objects are denser than water and some are less dense than water
Anti proton are short lived anti-particles of protons that has a charge of -1. When they encounter their counter part, which is the proton, they exist for a short span of time only since they will be annihilated and burst into a form of energy.
True. A gas does not have a definite volume. Therefore, making this statement correct. <span />
Answer:The bubbles exhaled by a scuba diver grow as they approach the surface of the ocean. The pressure exerted by the weight of the water decreases with depth, so the volume of the bubbles increases as they rise.
Explanation:
2Al+6HCl ->2AlCl3+3H2 .nAl=m/M=13,5/27=0,5(mol) =>nH2=0,5.3/2=0,75(mol)....VH2=n.22,4=0,75.22,4=16,8(lít)...
