Thermal expansion<span> is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.</span>
Answer:
See explanation
Explanation:
Molar mass is obtained as the sum of relative atomic masses as follow;
For CaBr = 40.08 + 79.90 = 119.98 g/mol
For BeBr = 9.012 + 79.90 = 88.912 g/mol
For CdBr2 = 112.41 + 2(79.90) = 272.21 g/mol
For CuBr2 = 63.55 + 2(79.90) = 223.35 g/mol

I honeslty dont know if this is right
explanation:
Answer: The suffixes of the names of polyatomic ions have a pattern associated with them. ... For example, the sulfite ion has three oxygen atoms whereas the sulfate ion has four oxygen atoms.
