What is the proportion by mass of hydrogen to oxygen in hydrogen peroxide?
The proportion by mass of hydrogen to oxygen in hydrogen peroxide is 1:16. This means that for every 1 gram of hydrogen in hydrogen peroxide, there are 16 grams of oxygen.
Does hydrogen peroxide have a density of 1.44 grams per cubic centimeter?
Yes, hydrogen peroxide has a density of approximately 1.44 grams per cubic centimeter at room temperature.
How much does 35 percent hydrogen peroxide weight per gallon?
Hydrogen peroxide has a density of about 1.2 grams per milliliter. To convert this to pounds per gallon, there are roughly 3.785 liters in a gallon (1 gallon = 3.785 liters) and 1 gram is about 0.00220462 pounds. Therefore, 35% hydrogen peroxide would weigh approximately 16.7 pounds per gallon.
How many hydrogen molecules are needed to produce 525 grams of ammonia?
To produce 525 grams of ammonia (NH3), you would need 25 moles of ammonia. Since the balanced chemical equation for the reaction between hydrogen and nitrogen to form ammonia is 3H2 + N2 -> 2NH3, you would need 75 moles of hydrogen molecules (H2) to produce 525 grams of ammonia. This is equivalent to 4,500 molecules of hydrogen.
How many hydrogen peroxide molecules are expected if 100 oxygen molecules react with 10 hydrogen molecules?
If 100 oxygen molecules react with 10 hydrogen molecules to produce hydrogen peroxide, then 10 hydrogen peroxide molecules are expected, because each hydrogen peroxide molecule requires one oxygen and one hydrogen molecule for its formation.
