Attempt 3 an irregular lump of an unknown metal has a measured density of 5.50 g/ml. the metal is heated to a temperature of 153 °c and placed in a graduated cylinder filled with 25.0 ml of water at 25.0 °c. after the system has reached thermal equilibrium, the volume in the cylinder is read at 30.0 ml, and the temperature is recorded as 41.0 °c. what is the specific heat of the unknown metal sample? assume no heat is lost to the surroundings.

Type the letter that represents the correct location for each particle type below.

The following reaction shows the products when sulfuric acid and aluminum hydroxide react. al(oh)3 + h2so4 → al2(so4)3 + h2o the table shows the calculated amounts of reactants and products when the reaction was conducted in a laboratory. sulfuric acid aluminum hydroxide initial amount of reactant 40 g 15 g theoretical yield of water from reactant 14.69 g 10.38 g what is the approximate amount of the leftover reactant? 11.73 g of sulfuric acid 10.33 g of sulfuric acid 11.12 g of aluminum hydroxide 13.67 g of aluminum hydroxide

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
