Explanation:
Magnesium carbonate can be prepared in laboratory by reaction between any soluble magnesium salt and sodium bicarbonate: MgCl2(aq) + 2NaHCO3(aq) → MgCO3(s) + 2NaCl(aq) + H2O(l) + CO2(g)
Answer:
The human body contains trillions of microorganisms — outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that's 2 to 6 pounds of bacteria), but play a vital role in human health.
The molar mass of Zinc is 65.38 u

Answer:
The answers to your question are given below
Explanation:
The equation for the reaction is given below:
2KClO₃ —> 2KCl + 3O₂
The total number of each atoms present in the reactants and products can be obtained by doing a head count as illustrated below:
Reactants >>>>>> Number of atoms
Potassium (K) >>> 2 × 1 = 2
Chlorine (Cl) >>>> 2 × 1 = 2
Oxygen (O) >>>>> 2 × 3 = 6
Products >>>>>>> Number of atoms
Potassium (K) >>> 2 × 1 = 2
Chlorine (Cl) >>>> 2 × 1 = 2
Oxygen (O) >>>>> 3 × 2 = 6
