What else can I help you with?
How many water molecules (H2O) can be produced from 6 molecules of hydrogen gas (purple) reacting with 6 molecules of oxygen gas (turquoise)?
6H2 + 6O2 ---> 6H2O + 3O2 This reaction leave excess unreacted oxygen behind.
What is the volume of hydrogen gas when a sample of 9 grams of aluminum metal is added to an excess of hydrochloric acid?
The reaction between aluminum metal and hydrochloric acid produces hydrogen gas and aluminum chloride. To find the volume of hydrogen gas produced, you would need to know the molarity of the hydrochloric acid and the temperature and pressure of the reaction. Once you have that information, you can use the ideal gas law to calculate the volume of hydrogen gas produced.
How many molecules are produced when 2.5g of zinc react with an excess of hydrochloric acid?
To determine the number of molecules produced, we first need to convert the mass of zinc (2.5g) to moles using the molar mass of zinc. Then, we calculate the number of moles of zinc reactant that reacted. From the balanced chemical equation, we can see that one mole of zinc produces one mole of zinc chloride molecules. Finally, we can use Avogadro's number to convert moles of molecules to actual molecules.
What is a compound that produces an excess of hydrogen ions in water?
An example of a compound that produces an excess of hydrogen ions in water is hydrochloric acid (HCl). When HCl is dissolved in water, it dissociates into hydrogen ions (H+) and chloride ions (Cl-) leading to an increase in the concentration of H+ ions.
What is the mass of hydrogen gas released from 2.70 g of aluminum metal and hydrochloric acid in grams?
I assume you mean excess hydrochloric acid. Balanced equation. 2Al + 6HCl = 2AlCl3 + 3H2 2.70 grams Al (1 mole Al/26.98 grams)(3 mole H2/2 mole Al)(2.016 grams/1 mole H2) = 0.303 grams hydrogen gas produced --------------------------------------------------
When acids in water what positive ion is produced in excess?
When acids in water hydrogen positive ion is produced in excess. It is this hydrogen positive ion that gives acidity of a solution.
What positive ions is produced in excess when acids are dissolved in water?
Hydronium(H3O+) ions, which are formed when Hydrogen(H+) ions combine with water molecules.

What molecules are produced from excess fat breakdown?
Mostly free fatty acids and triglycerides.
How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
What volume of hydrogen measured at 0.95 ATM and 27c can be prepared by the reaction of 0.500 mole zinc with an excess of hydrochloric acid?
12.9 L

How can you tell when as excess of hydrochloric acid has been added to the evaporating dish with the magnesium?
When excess hydrochloric acid has been added to an evaporating dish with magnesium, you will observe bubbling and fizzing as the magnesium reacts with the acid. Once all the magnesium has been consumed in the reaction, no more bubbles will be produced, indicating that excess acid is present.
What is the color of the indicator when an excess of hydrochloric acid has been added?
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
