Calculate the number of millimoles of hydrochloric acid that can theoretically be neutralized by a 500.mg TumsTM tablet.

10 mmol

Explanation:

TumsTM is made of CaCO3

Reaction equation:

2HCl(aq) + CaCO3(aq) > CaCl2(aq) + H20(l) + CO2(g)

number of moles in 500mg of TumsTM = 500 * 10^-3/100 = 5 * 10^-3 moles

if from the balanced equation;

2 moles of HCl reacts with 1 mole of CaCO3

x moles of HCl will rect with 5 * 10^-3 moles of CaCO3

x= 5 * 10^-3 moles * 2 mole/1 mole = 0.01 mole or 10 mmol

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces
