Interpretation:
The coefficients that balance the given equation has to be found out.
Concept Introduction:
Chemical reaction can be entered in form of a chemical equation. The total number of atoms of the same element in both sides of the arrow in a chemical equation has to be equal. Once, this is same, then the equation obtained is known as balanced chemical equation. For balancing chemical equation, the coefficients alone can be modified and not the subscripts of the atoms in the formula.

A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.arrow_forwardTwo general chemistry students working together in the lab weigh out 0.832 g of CaCl2 2 H2O into a crucible. After heating the sample for a short time and allowing the crucible to cool, the students determine that the sample has a mass of 0.739 g. They then do a quick calculation. On the basis of this calculation, what should they do next? (a) Congratulate themselves on a job well done. (b) Assume the bottle of CaCl2 2 H2O was mislabeled; it actually contained something different. (c) Heat the crucible again, and then reweigh it.arrow_forward
