A 5-g sample of impure magnesium carbonate is reacted with an excess of hydrochloric acid: MgCO3 (s) 1 2HCl (aq) MgCl2 (aq) 1 H2O (l) 1 CO2 ( g) 1250 cm3 of carbon dioxide is collected at rtp. a How many moles of CO2 are produced? b What mass of pure magnesium carbonate would give this volume of carbon dioxide? (Ar : C 5 12, O 5 16, Mg 5 24.) c Calculate the % purity of the 5-g sample.​

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Can you me with this i really appreciate it
