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?

Write a balanced chemical equation for the following reactions and classify reactions. i. Liquid octane (C8H18) reacts with oxygen gas (O2) to form carbon dioxide and steam (gaseous water). ii. Solid sodium metal and water react to make sodium hydroxide and hydrogen gas.

How do I get to this answer?

The combustion of gasoline produces carbon dioxide and water. Assume gasoline to be pure octane (C8H18) and calculate how many kilograms of carbon dioxide are added to the atmosphere per 5.4 kgkg of octane burned. (Hint: Begin by writing a balanced equation for the combustion reaction.)

I need help understanding how to do this homework question. I've been out sick so I don't even know how to even begin to attempt this question.
