Agas is inside a cylinder fitted with a piston. the gas and its surroundings are both at 20 ∘c and the gas is compressed as the piston moves and decreases the cylinder volume. the compression takes place slowly enough to allow the gas temperature to stay at 20 ∘c and the work done on the gas by the compression is 2.4 × 103 j.

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls

Which element is the least metallic between cadmium, silver, zinc, or iron?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
