5. Combustion reaction – When a compound containing C and H or C, H, and O is burned in the presence of oxygen, O,(g)), the products of complete combustion are always carbon dioxide gas and water (either liquid or vapor). • Write the products of the complete combustion for the reaction below. Balance the chemical equation Write the net ionic equation. C,H,,0,(s) O,

Chromium(III) ions are very poisonous. They can be removed from solution by precipitating very insouble chromium(III) hydroxide. Chromium(III) chloride reacts with calcium hydroxide to form chromium(III) hydroxide and calcium chloride.   Write the balanced formula unit equation for the reaction stated above. Now, determine the total ionic equation for the reaction stated above. Now write the balanced net ionic equation for the reaction stated above.

Follow the given example of no.1

Hexane is a colourless liquid with a characteristic smell that reacts with chlorine gas in the presence of a catalyst. Chlorohexane is a liquid compound that is formed through the substitution of one hydrogen in the hexane molecule with chlorine. Write the chemical equation for this reaction and explain if it requires balancing. Hydrogen chloride gas is also a product of this chemical reaction. Note: ignore the presence of the catalyst.

1) Group 1 metals react almost instantly and violently with water, as a single replacement reaction to produce an aqueous solution of metal hydroxide and hydrogen gas. A sample of solid lithium weighing 84.25 mg is dropped into a beaker containing 50.0 mL of water. Assume the density of water is 0.9988 g/mL. a) Write the balanced equation. b) Calculate the theoretical yield (in grams) of lithium hydroxide. c) Assuming the reaction is complete, and that there is no volume change, what is the concentration (in M) of lithium hydroxide in the solution that results?

Balance Equation: 2Al + 3CuCl2 * 2H2O -> 2Cu + 2AlCl3 + 6H20 1. Reproduce the following table in your document. Write the chemical reaction again in the indicated spot, typing the reactants under the word “reactants” and products under the word “products”. Then in the row labeled “Element”, list each element in the reactants and products. Assign oxidation numbers to each element in the reactants and products and write the oxidation number underneath each element in the table below. Explain how these were derived. (see table) 2. From the reactants, identify the oxidizing agent and reducing agent and input this into the table above. Explain, in a few sentences, how you determined the difference between the two. 3. Type out the complete ionic equation and the net ionic equation for the reaction. Explain how you arrived at your answer in a narrative (3-5 sentences), including why you canceled any ions as spectators.

What is the mass of the initial sample burned?

Correctly balance the following chemical equation. When there is no coefficient to add enter the number 1 into the box. Al + Cuclz--> AlCl3 + Cu

Baking soda is a pure substance, sodium bicarbonate. Vinegar is a mixture of acetic acid dissolved in water, and it is only the acetic acid that reacts. Acetic acid and sodium bicarbonate can react together according to the chemical equation below: HC2H302 NaHCOe NAC2H302 + H20 + CO2 acetic acid + sodium bicarbonate sodium acetate + water + carbon dioxide Samuel wants to help his brother make a science fair volcano. 1. For his first experiment, Samuel obtains samples of solid acetic acid powder and solid sodium bicarbonate powder from his chemistry teacher. He mixes the two powders together, but there is no reaction. b) Considering the state of matter of the particles, give a possible explanation for why there is no reaction.
