Question 9 (16 marks) In a laboratory, an experiment was carried out to demonstrate the chemical reaction between
nitric acid and sodium hydrogencarbonate. The molecular equation can be written as follows.
I
HNO3(aq) + NaHCO3(s) - NaNO3(aq) + CO2(g) + H2O(1)

Calculate the volume of CO2(g) that is produced at 25 °C and 1.00 atm when 10.0 mL of 2.00
mol/L HNO3 reacts with 1.00 g NaHCO3 (molar mass = 84.006 g/mol). Clearly show your
working, including a statement about the mole ratios of the substances in the reaction, and state
the unit.​

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.

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally
