When hydrogen fuses with hydrogen what new element does this produce?
When hydrogen is fused in the suns core Helium is produced.
How many moles of ammonia are produced from 12.0 moles of hydrogen?
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
What is the gas produced when sodium reacts with water?
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
What is produced when hydrogen and oxygen react together?
Hydrogen and oxygen can react to produce water or hydrogen peroxide. Hydrogen peroxide is produced by a complicated process, but the overall equation is H2 + O2 ---> H2O2. Water is produced by the reaction of 2H2 + O2 --->2H2O.
One nitrogen molecule reacts with three hydrogen molecules to produce two ammonia molecules each containing one nitrogen and three hydrogen atoms?
One ammonia molecule will be produced.
What acid does sodium combine with to make hydrogen gas?
Sodium will react with virtually any acid to produce hydrogen gas. However the heat produced by such a reaction usually ignites the hydrogen.
What substance will you produce when you combine hydrogen and oxygen?
water
When hydrogen fuses with hydrogen what new element does this produce?
When hydrogen is fused in the suns core Helium is produced.
Can helium be turned into hydrogen to produce energy?
No, energy is produced by the opposite reaction, hydrogen to helium
How does sun produce thermal energy?
The thermal energy in sun is produced due to the process of nuclear fusion in which two hydrogen atoms combine to form one helium atom.
How you produce oxygen?
It can be produced by electrolysis of water. Which disassociates the Hydrogen and Oxygen molecules.
How many moles of ammonia are produced from 12.0 moles of hydrogen?
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
Which fuel causes minimum environmental pollution. A hydrogen B coal C diesel D kerosene?
hydrogenA2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.
Some bacteria that are adapted to live without oxygen combine carbon dioxide and hydrogen to produce?
methane
What does bacteria that are adapted to live without oxygen combine carbon dioxide and hydrogen to produce?
Methane is correct
What gas is produced when magnesium reacts with zinc?
I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
What is the gas produced when sodium reacts with water?
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
