When a chemical reaction occurs, atoms rearrange to form new 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 Part A 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. • View Available Hint(s) ΑΣφ ? OA chemical reaction does not occur for this question. Figure < 1 of 1>

Part B Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: ? H3PO4 + ? Mg(OH)2 → ? Mg3 (PO4)2 + ? H2O Balance the equation, then enter the coefficients, in order, in the answer box. Enter four integers separated by commas. • View Available Hint(s) Part C You carefully weigh out 15.00 g of CaCO3 powder and add it to 60.75 g of HCl solution. You notice bubbles as a reaction takes place. You then weigh the resulting solution and find that it has a mass of 69.60 g . The relevant equation is CACO3 (s) + 2HCI(aq)→H2O(1) + CO2 (g) + CaCl2 (aq) Assuming no other reactions take place, what mass of CO2 was produced in this reaction? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) HA ?
