25 cm3 of potassium hydroxide solution react with 20 cm3 of 2 mol/dm3 sulfuric acid. The chemical equation for the reaction is given below: 2KOH (aq) + H2SO4(aq) → K2SO4(aq) + 2H2O (l)

Calculate the number of mol of sulfuric acid (2 marks)

Calculate the number of mol of KOH which reacted with the number of mol of the acid in (a) ( 1 mark)

Calculate the concentration of KOH in mol/dm3 ( 2 marks)

Calculate the number of mol of potassium sulfate (K2SO4) produced ( 1mark)

Calculate the mass in grams of potassium sulfate produced (Relative atomic masses: K =39, S =32, O =16). ( Hint: first calculate the relative formula mass of potassium sulfate, (K2SO4) ( 3 marks)

Actual ingredients of lab (the cookies i am actually making) 1/2 cup sugar 1/2 cup brown sugar 1 1/3 stick margarine 1 egg 1/2 tsp salt 1 tsp vanilla 1/2 tsp baking soda 1 1/2 cup flour 1 1/3 cup chocolate chip can you answer the questions below ? discussion 1. suppose you are given the following amounts of ingredients: 1 dozen eggs 24 tsp. of vanilla 1 lb. (82 tsp.) of salt 1 lb. (84 tsp.) of baking soda 3 cups of chocolate chips 5 lb. (11 cups) of sugar 2 lb. (4 cups) of brown sugar 1 lb. (4 sticks) of margarine a. for each ingredient, calculate how many cookies could be prepared if all of that ingredient were consumed. (for example, the recipe shows that using 1 egg- with the right amounts of the other ingredients- yields 24 cookies. how many cookies can you make if the recipe is increased proportionately for 12 eggs? ) b. to determine the limiting reactant for the new ingredients list, identify which ingredient will result in the fewest number of cookies. c. what is the maximum number of cookies that can be produced from the new amounts of ingredients?

What is the correct lewis structure for chloroform chcl3

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?
