(h) A piece of solid bismuth is heated (i) A strip of copper metal is added to a concentrated solution of sulfuric acid. (j) A strip of copper is immersed in dilute nitric acid. (k) If 204.5 g of copper (II) nitrate is formed in the above reaction: 1. How many moles are formed? 2. How many atoms of oxygen are formed? 3. What is the mass percent of nitrogen in the copper (II) nitrate? 6
Even more reactions & equations 1. Balance these reactions. Give reaction type for each, and complete each reaction, if it is not already completed. a. LiOH(aq) + H3PO4(aq) ----> H2O(l) + Li3PO4(aq) b. NH4Cl(s) + Mg(OH)2(s) ----> _________(g) + _________(l) + _________(aq) c. CaO(s) + HNO3(aq) ----> d. CuCO3(s) + HBr(aq) ----> e. BaCl2(aq) + NaOH(aq) ----> Ba(OH)2(s) + NaCl(aq) 2. Write a balanced equation for the following descriptions of reactions. a. When metals react with acids, hydrogen gas and a salt are produced. The salt is formed from the metal cation and the acid anion. If the salt that is produced is soluble in water, it will be dissolved in the water that is produced. Write the equation that takes place between calcium metal and phosphoric acid solution. b. When metal carbonates are heated, carbon dioxide gas is produced along with the solid oxide of the metal. Write a balanced equation for the formation of barium oxide from barium carbonate. (Barium ions have a charge of +2.) c. Hydrogen peroxide (a liquid at room temperature) decomposes when exposed to sunlight. (That's why it always comes in brown opaque bottles.) Water is one product, and the other product is a gas that is able to relight a glowing splint. Write the equation showing the decomposition of hydrogen peroxide. 3. Predict the products and balance the reactions. Give reaction type. REFER TO YOR NOTES! a. BaSO4(aq) + Ag(s) ----> ___________(s) + __________(aq) b. Mg(s) + HCl(aq) ----> __________(aq) + __________(g) c. Ca(NO3)2(aq) + Mg(s) ----> __________(aq) + __________(s) d. MgCO3(s) -----> 7
