How does a chemical reaction obey the law of conservation of matter? A The same number of molecules appear in the reactants and products. B C The total mass of the reactants is equal to the total mass of the products. The total number of chemical bonds in the reactants is the same as the number of bonds in the products. The same number of reactant particles as product particles are involved in the reaction.

Write the empirical formula for at least four ionic compounds that could be formed from the following ions:

Write the correct formulas and balance the equations:A. Gallium plus perchloric acid yields gallium perchlorate plus water plus dichlorine pentoxide. (Note: the coefficient of the water is 9 and the coefficient of dichlorine pentoxide is 3.) B. Aluminum hydroxide plus sulfuric acid yields aluminum sulfate plus water.

How does a chemical reaction obey the law of conservation of matter? A C D The same number of molecules appear in the reactants as appear in the products. The total mass of the reactants is equal to the total mass of the products. The same total number of chemical bonds are in the reactants as are in the products. The same number of reactant particles as product particles are in- volved in the reaction.

When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this reaction in terms of A and B. Express your answer as a chemical equation. When balancing chemical equations with polyatomic ions, it may help to balance the ion as a whole. For example, the ion PO_4^3 can be treated as a unit and balanced in both the reactants and the product, or you can break it down and balance each atom separately. Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: Balance the equation, then enter the coefficients, in order, in the answer…

3) Show your calculations clearly. Suppose you are provided with a 36.55 g sample of potassium chlorate.a. What mass of oxygen should theoretically be released upon heating? b. What mass of potassium chloride residue should theoretically be left over after heating?
