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

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
