If 40 grams of sodium hydroxide and 3 grams of hydrogen gas are produced when 27 grams of sodium metal is consumed how many grams of liquid water must have been added?

27 g Na + H2O = 40 g NaOH + 3 g H2.
Law of Conservation of Mass. The reactants must have the same number of grams of the products. 40 + 3 = 43. 43 - 27 = 16 g H2O.

What are two methods for producing hydrogen?
Hydrogen can be produced by: - Compressing air to the point where it becomes a liquid. Then the process of fractional distillation is used on this liquid air. - Hydrogen can be obtained by the steam reforming of methane. - Reacting some metals with water yields a base and hydrogen gas. <><><> Hydrogen can also be produced by eletrolysis of water, splitting it into oxygen and hydrogen.
Is hydroxide a liquid or gas?
"hydroxide" is a term for an ion. Ions do not inherently belong to any particular phase. You have to specify which kind of molecule the hydroxide belongs to before a valid answer can be provided.
Is hydroxide a liquid?
The term hydroxide is generally used to refer to an ion and not a "substance" per se. In that light, hydroxide cannot be a solid, liquid or gas as we think of atoms or molecules. The hydroxide ion is a bonded pair of atoms, one of oxygen and one of hydrogen. It has the chemical symbol OH- because this ion "came from somewhere" with a "partner" ion that a "+" charge on it. The ions, because they are in a situation where they've become separated from each other, are not generally considered using the term "liquid" when we look at them (even though they may be in liquid solution).
When solid sodium is added to liquid water it reacts with the water to produce hydrogen gas and aqueous sodium hydroxide what does the formula look like?
2Na + 2H2O--->H2+ 2NaOH Hydrogen gas is diatomic, therefore it requires a subscript of 2.
What is the name of hydroxide used in making liquid soap?
Potassium hydroxide (KOH) is the alkali most often used in making handmade liquid soaps.
Is hydrogen hydroxide a liquid?
This is a trick question hydrogen hydroxide could be a name for HOH, H2O water and yes that is a liquid at room temperature. It is not a proper chemical name so don't start calling water hydrogen hydroxide when answering chemistry questions.
How can you tell if a liquid is a base?
hydrogen ions and hydroxide ions....
What happens if you mix sodium hydrogen and calcium hydroxide as a liquid?
Sodium react with water and release hydrogen.Sodium hydroxide is also formed. Calcium hydroxide remain unchanged.
If you chemically mix Oxygen gas with Hydrogen gas then which liquid is produced?
If one chemically reacts oxygen gas and hydrogen gas, any liquid produced is water.
What happens if K keep in air?
Potassium oxidizes immediately when exposed to air. It also reacts violently in water, producing potassium hydroxide and hydrogen gas. The hydrogen gas produced will burn spontaneously, so potassium is always stored in a liquid with which it does not react, such as kerosene.
Is amonium hydroxide a liquid metal?
Ammonium hydroxide is neither a metal nor a liquid. It is an compound consisting of the nonmetals nitrogen, hydrogen, and oxygen that only exists in small amounts in solutions of ammonia dissolved in water. The only liquid metal is mercury.
What characteristic does water gas and liquid share?
they are both different phases of the same thing (hydrogen hydroxide, so to speak).

Why are hydrogen ions and hydroxide ions omitted from the net reaction for the hydrolysis of water?
The two ions tend to recombine to form liquid water

What is the balanced equation for Liquid water is produced when hydrogen gas and oxygen gas combine?
H2o 2h2 + o2 = 2h2o
