A student collects a 125.0mL sample of hydrogen gas, but forgot to record the temperature. Later the sample is found to have a volume of 128.6mL when the temperature is 26.0oC. What was the original temperature, in Kelvin, of the gas? Show all your work and round your answer to the hundredths place.

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
