How much water is made using 2kg hydrogen and 16kg of oxygen?
This equation and finding the limiting reactant.2H2 + O2 -> 2H2O2 kg H2 (1000 g H/1 kg H)(1 mole H/2.016 grams)= 992 moles hydrogen16 kg O2 (1000 g/1 kg)(1 mole O2/32.0 grams)= 500 moles oxygenI suspect hydrogen limits. Let's see.992 mole H2 (1 mole O2/2 mole H2)= 496 moles O2You have just a bit more than this in oxygen, so enough and hydrogen limits. ( check by going the other way and see the hydrogen limits )So, hydrogen drives the reaction.2 kg H2 (1000 g/1 kg)(1 mole H2/ 2.016 g)(2 mole H2O/2 mole H2)(18.016 g/1 mole H2O)(1 kg/1000 g)= 17.87 kilograms water made=========================( you do the significant figures )
What of each reactant would be needed to produce 100.0 kg of methanol?
1 mole of carbon monoxide and 2 moles of diatomic hydrogen.
Which element combines with Hydrogen to form water?
Hydrogen. 2 hydrogens to be exact
How are hydrogen 1 and hydrogen 2 alike?
Hydrogen-1 and hydrogen-2 are alike in that they both have one proton in the nuclei of their atoms.
What is the pH of a hydrogen solution that has a hydrogen concentration of 10-2?
If concentration of Hydrogen in solution is 10-2 then its pH must be 2.

How much energy is produced by the fusion of 1 kg of hydrogen?
Hydrogen has one of the highest energy density values per mass. Its energy density is between 120 (33.333kWh) and 142 MJ/kg (39.444kWh). This means that for every 1 kg of mass of hydrogen, it has an energy value of 120-142 MJ. It is highly flammable, needing only a small amount of energy to ignite and burn. Hydrogen burns cleanly. When it is burned with oxygen, the only by products are heat and water.
Which one is more 1 kg or 2 kg?
2 kg is more.
What is 25 percent of 2kg?
25% of 2 kg= 25% * 2 kg= 0.25 * 2 kg= 0.50 kg
Which one is larger 2 tonnes or 3000 kg?
Convert to the same units then a comparison can be made: 1 tonne = 1000 kg → 2 tonne = 2 × 1000 kg = 2000 kg 2000 < 3000 → 2000 kg < 3000 kg → 2 tonnes < 3000 kg 3000 kg is larger than 2 tonnes.
How many atoms are there in the sun if all the atoms are hydrogen and if the mass of the sun is 2 x 10 to the power of 30 kg and the mass of a hydrogen atom is 1.67 x 10 to the power of -27 kg?
Mass of 1 hydrogen atom = 1.67 × 10−27 kgMass of sun = 2 x 1030 kgSo the ratio of the mass of the sun to that of a H atom= (2 x 1030) / (1.67 × 10−27)= (2 / 1.67) x (1030 / 10−27)= 1.2 x 1057If the sun were entirely composed of H atoms, this would be the number of H atoms in the sun.
