Na +H2O -> NaOH +(1/2)H2
Every mole of Sodium requires one mole of water to make one mole of Sodium Hydroxide.
So two moles of Sodium will produce two moles of Sodium Hydroxide. If there are three moles of water in the initial reaction then there will be one mole of water left over after reacting with two moles of Sodium. This reaction will produce half a mole of hydrogen gas.

Why is pure water neutral despite the fact the production of hydrogen ions and hydroxide ions?
Because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral. Water is neutral despite the production of hydrogen ions and hydroxide ions because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral.
What solutions have a greater number of hydroxide ions than hydrogen ions?
An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.
What would happen to the concentration of hydrogen ions in a solution of a strong acid if an equal number of hydroxide ions were added to the solution?
It produces a neutral salt along with water
How many grams of calcium hydroxide can be produced from 312 g of CaO?
CaO has a gram molecular mass of 40.08 + 16.00 = 56.08. The reaction between CaO and water to produce calcium hydroxide, Ca(OH)2, occurs according to the equation CaO + H2O = Ca(OH)2. Therefore, the same number of moles of calcium hydroxide can be produced as the moles of CaO supplied. The gram molecular mass of Ca(OH)2 is 40.08 + 2 (16.00 + 1.008) = 74.10. Therefore, the mass of calcium hydroxide produced with have the same ratio to the mass of calcium oxide supplied as 74.10 has to 56.08, or 412 grams, to the justified number of significant digits.
What group number is hydrogen?
The element Hydrogen is in the group number 1.
Why is pure water neutral despite the fact the production of hydrogen ions and hydroxide ions?
Because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral. Water is neutral despite the production of hydrogen ions and hydroxide ions because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral.
What is pH pure water (neutral)?
pure water is neutral with a pH of 7
A neutral solution has an equal numbe of?
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
What is the oxidation number of oxygen in hydroxide?
Oxygen in hydroxide has the oxidation number -2. This combines with the oxidation number +1 of hydrogen to form an anion with net charge of -1.
Why is water considered to be a neutral?
Because the number of hydrogen ions are the same as the number of Hydroxide ions.
What is the number of Hydrogen ions in 5.18 g of strontium hydroxide?
Strontium hydroxide is Sr(OH)2, with a molar mass of 121.6g/mol. If you have 5.18g of it, you have 5.18/121.6=0.0426mol of it. Multiply this by Avogadro's number to get 2.56x1022 representative particles of strontium hydroxide. Assuming you mean hydroxide ions instead of hydrogen ions, it's 2 hydroxide ions per formula unit, so double it to get 5.12x1022 hydroxide ions.
What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?
A neutral solution of about 7 pH.
Compare acids and bases based on the ion produced when each compound is dissolved in water?
Acids- number of hydrogen ions increases when dissolved in water. Bases- number of hydroxide ions increases when dissolved in water I had the same question, but I had it for homework (:
How does the number of hydrogen ions compare to the number of hydroxide ions?
In pure water, at standard conditions, the number of hydrogen ions (H⁺) is equal to the number of hydroxide ions (OH⁻). This balance occurs due to the self-ionization of water molecules: H 2 O ⇌ H OH − H 2 O⇌H +OH − For every water molecule that dissociates, one hydrogen ion (H⁺) and one hydroxide ion (OH⁻) are produced. The concentration of hydrogen ions (H⁺) is often denoted as [H⁺], and the concentration of hydroxide ions (OH⁻) is denoted as [OH⁻]. In neutral water (pH 7), these concentrations are equal: [H+]=[H−]=10−7 mol/L [H+ ]=[OH− ]=10−7 mol/L This balance ensures that the solution remains neutral. However, in acidic solutions, the concentration of hydrogen ions (H⁺) is higher than that of hydroxide ions (OH⁻), while in basic solutions, the concentration of hydroxide ions (OH⁻) is higher than that of hydrogen ions (H⁺). The product of the hydrogen ion concentration and the hydroxide ion concentration is always 10−14 mol 2 / L210−14 mol2 /L2 at 25°C, known as the ion product of water.
What is the number of atoms in cupric hydroxide?
5 atoms = 1 Copper + 2 Hydrogen + 2 Oxygen
What Is a substance that produces hydroxide ions in solution.?
A base does this. The hydroxide (OH-) ion appears in solution. An acid produces hydrogen (or hydronium) ions in solution, and not hydroxide ions.
Determine the number of hydrogen ions when you are given 2 moles of water?
4 moles of hydrogen atoms
