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?

For the reaction of nitrogen dioxide with water to form nitric acid and nitrogen monoxide, what is the sum of the coefficients of the balanced equation?

Pure magnesium metal is often found as ribbons and can easily burn in the presence of oxygen. When 2.47 g2.47 g of magnesium ribbon burns with 8.71 g8.71 g of oxygen, a bright, white light and a white, powdery product are formed. Enter the balanced chemical equation for this reaction. Be sure to include all physical states. equation:   What is the limiting reactant? magnesium oxygen If the percent yield for the reaction is 83.4%,83.4%, how many grams of product were formed? mass of product formed:   gg How many grams of the excess reactant remain? mass of excess reactant:

In the balanced equation for the complete neutralization of phosphoric acid by calcium hydroxide, the mole:mole ratio of phosphoric acid to calcium hydroxide is

For the following reaction,0.483 moles of silver nitrate are mixed with0.203 moles of copper.   What is the formula for the limiting reagent?   What is the maximum amount of copper(II) nitrate that can be produced? moles

1. A bright yellow precipitate is produced in a laboratory reaction, when lead(II) nitrate solution is reacted with potassium iodide solution. How many moles of a precipitate are produced when 256 mL of a 1.5 mol/L potassium iodide solution is reacted with excess lead(II) nitrate solution? Hint: Write a balanced chemical reaction equation first.(Record only your final answer with the correct number of significant digits and the proper units.)
