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 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 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 --------------------------------------------------
An excess of Mg is reacted with 1 mole of HCl dissolved in water- determine the mass of hydrogen produced?
The reaction between magnesium and hydrochloric acid produces hydrogen gas according to the equation: Mg + 2HCl -> MgCl2 + H2. For every 1 mole of magnesium reacted, 1 mole of hydrogen gas is produced. Using the molar mass of hydrogen (1 g/mol), the mass of hydrogen produced would be 1 gram when 1 mole of magnesium is reacted.
When mg and hydrochloric acid react why is it exothermic?
When magnesium reacts with hydrochloric acid, energy is released in the form of heat because new chemical bonds are formed in the products (magnesium chloride and hydrogen gas) that are more stable than the reactants. This excess energy is given off as heat, making the reaction exothermic.
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 many moles of tungsten can be produced from 2405moles of hydrogen and excess WO3?
The reaction is:WO3 + 3 H2 = W + 3 H2OThree moles of hydrogen for one mole of wolfram.
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 characteristics of a fission reaction makes a chain reaction possible?
The excess of neutrons produced.

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 effect of olefin concentration on naphtha hydrotreating process?
Hydrotreating reaction is an exothermic reaction. The total reaction provides excess reaction heat; more is produced by the exothermic hydrogenation reactions than are required to support the endothermic cracking reactions.High Olefin conc. leads to high temp. rise due to hydrogenation reaction.This excess heat increases the reactor temperature and accelerates the reaction rate. Temperature rise can be controlled by injecting cold hydrogen or cold recycled quench into the reactors to absorb excess reaction heat.
Why is the solution boiled after adding excess hydrochloric acid to the solid hydrate?
to remove carbondioxide from the solution and also to increase the rate of reaction
