How many moles of hydrogen iodide are produced from 1 mole of iodine?
The balanced equation for the reaction between Iodine and Hydrogen is: H2 + I2 --> 2HI The ratio of I2 to HI is 1:2 Therefore 1 mole of Iodine can form a maximum of 2 moles of Hydrogen Iodide
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 mass of hydrogen is produced when 24g of magnesium react with an excess of sulfuric acid?
To find the mass of hydrogen gas produced, start by determining the moles of magnesium reacting by dividing the mass of magnesium by its molar mass. Then, use the balanced chemical equation to find the moles of hydrogen gas produced, as it is a 1:1 ratio with magnesium. Lastly, convert the moles of hydrogen gas to grams to find the mass.
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.
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 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.
How many liters of water can be produced if 250 moles of O2 are reacted with excess hydrogen?
Since 1 mole of O2 reacts with 2 moles of hydrogen to produce 2 moles of water, 250 moles of O2 will produce 500 moles of water. Assuming ideal gas behavior and STP conditions, 1 mole of gas occupies 22.4 L, so 500 moles of water will occupy 11,200 liters.
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.
Is more or less hydrogen produced when reacted with zinc insted of magnesium?
No, both magnesium and zinc produce the same amount of hydrogen when the same amounts react with excess of strong acid (on molecular base), though the second reaction is slower. The reaction equations can tell you more about why this is.Mg + 2H+ --> Mg2+ + H2Zn + 2H+ --> Zn2+ + H2
What mass of hydrogen is produced when 24g of magnesium react with an excess of sulfuric acid?
To find the mass of hydrogen gas produced, start by determining the moles of magnesium reacting by dividing the mass of magnesium by its molar mass. Then, use the balanced chemical equation to find the moles of hydrogen gas produced, as it is a 1:1 ratio with magnesium. Lastly, convert the moles of hydrogen gas to grams to find the mass.
How many moles of Co2 will be produced from the reaction of three moles of acetylene with excess oxygen?
6 moles
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.
If an excess of nitrogen is reacted with 3.41 grams of hydrogen how many grams of ammonia can be produced?
Balanced equation first. N2 + 3H2 >> 2NH3 (hydrogen is limiting and drives the reaction ) 3.41 grams H2 (1mol/2.016g )(2mol NH3/3mol H2 )(17.034g NH3/1mol NH3 ) = 19.2 grams of ammonia produced ( this is called the Born-Haber process )
How many moles of ammonia gas are produced by the reaction of 3 mole of nitrogen gas with excess hydrogen gas N2 H2 ---- NH3?
N2 + 3H2 --> 2NH3 You have been told, indirectly, that nitrogen limits and will drive the reaction. 3 moles N2 (2 moles NH3/1 mole N2) = 6 moles ammonia gas produced ========================
How many moles of hydrogen gas will be produced from 250.0 milliliters of a 3.0 M HCl in an excess of Mg?
To find the moles of HCl, first convert 250.0 mL to liters (0.250 L). Then, use the molarity (3.0 M) to calculate moles of HCl: 0.250 L x 3.0 mol/L = 0.75 moles of HCl. Since Mg is in excess, all HCl will react. The balanced equation is 2HCl + Mg -> MgCl2 + H2, so 0.75 moles of HCl will produce 0.75 moles of H2 gas.
