1. The formula of chloric acid is HClO3. a) true b) false 2. Bases react with active metals to produce hydrogen gas. a) true b) false 3. Aqueous solutions of acids and bases
Pediococci and lactobacilli convert l (+)-lactate to d (−)-lactate, which reacts with calcium to form insoluble calcium lactate crystals that appear as undesirable white specks in ripened Cheddar. In brine-salted cheeses, such as Dutch- and Swiss-type cheeses, contaminating salt-tolerant lactobacilli metabolize amino acids to give undesirable phenolic and putrid H 2 S-like flavors during
Solid sodium metal reacts with chlorine gas to produce solid sodium chloride. 2 Na ( s ) + Cl 2 ( g ) → 2 NaCl ( s ) Notice that in order to write and balance the equation correctly, it is important to remeer the seven elements that exist in nature as diatomic molecules (H 2 , N 2 , O 2 , F 2 , Cl 2 , Br 2 , and I 2 ).

Calcium, Strontium, and Barium These metals react with cold water with increasing vigor to give the metal hydroxide and hydrogen. Strontium and barium have reactivities similar to that of lithium. Calcium, for example, reacts fairly vigorously and exothermically with
1/6/2020· Water can gain entrance into a cable during shipping, handling, outside storage, accidental damage or cable joint or termination failures. Due to its highly negative redox potential, aluminium reacts with water to produce hydrogen gas according to the equation: 2Al + 3H2O → 3H2 + Al2O3.This chemical reaction may be of particular importance when it occurs between the strands of an aluminium
8. Calcium metal reacts with water to form calcium hydroxide and hydrogen gas. Ca (s) + 2H2O → Ca (OH)2 + H2 (g) 9. Potassium nitrate decomposes to form potassium nitrite and oxygen. 2 KNO3 (s) → 2 KNO2 (s) + O2 (g) 10. Barium metal reacts with
A solution of hydrochloric acid reacts with a solid calcium bicarbonate to produce water, carbon dioxide, and calcium chloride. 2 HCl (aq) + Ca(HCO 3) 2 (s) -> 2 H 2 O (l) + 2 CO 2 (g) + CaCl 2 (aq) Oxidation Nuers
