How many grams of phosphoric acid (with excess NH3) are required to produce 800 g of (NH4)2HPO4, a common fertilizer?arrow_forwardThe elements sodium, aluminum, and chlorine are in the same period.(a) Which has the greatest electronegativity?(b) Which of the atoms is smallest?(c) Write the Lewis structure for the simplest covalent compound that can form between aluminum and chlorine.(d) Will the oxide of each element be acidic, basic, or amphoteric?arrow_forward(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. When a non-metallic oxide reacts with water, a base will be formed as the product of the reaction. When a metallic oxide like phosphorous pentoxide reacts with water, a base will be formed as the product of the reaction. 2. When water is mixed with oxides, hydrogen gas is evolved. A red to blue color change in the litmus paper indicates that the solution tested is an acid. 3. The filtrate in any filtration process is left on the surface of the filter paper, while the residue is collected at the bottom of the flask/container after passing through the filter paper. In the distillation process, the methyl violet served as a compound to acidify the water. 4. In the Winkler Titration Method, the starch solution turns colorless in the presence of free iodine in the solution to be titrated. In the Winkler…arrow_forward
