Determine the number of moles of sodium hydroxide produced when 2 moles of sodium and 3 mol of water react to form soduim hydroxide and hydrogen gas?
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.
Name and number of elements of magniesium hydroxide?
Magnesium Hydroxide: Mg(OH)2 1 Mg 2 O 2 H
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?
The concentration of hydrogen ions would decrease because when hydroxide ions react with hydrogen ions, they form water. This reaction reduces the overall concentration of hydrogen ions in the solution.
What substance has and equal number of hydrogen ions as hydroxide ions?
Neutral, pH=7.0 by using:[H+]*[OH-] = Kw = 1.0*10-14and [H+]= [OH-]you will resolve this to [H+]= [OH-] = 10-7 and so pH = pOH = 7.0
What is pH pure water (neutral)?
pure water is neutral with a pH of 7
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 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.
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 are the oxidation numbers of hydroxide?
The oxidation number of oxygen in hydroxide (OH-) is -2 since oxygen typically has an oxidation number of -2 in compounds. The oxidation number of hydrogen in hydroxide is +1 since hydrogen usually has an oxidation number of +1 when bonded to nonmetals like oxygen.
Why is water considered to be a neutral?
Because the number of hydrogen ions are the same as the number of Hydroxide ions.
A neutral solution has an equal numbe of?
A neutral solution has an equal number of hydronium ions (H3O+) and hydroxide ions (OH-) present, resulting in a balanced pH of 7. This equilibrium reflects the concentration of hydrogen ions being equal to the concentration of hydroxide ions in the solution.
Why is water neutral despite to production of hydrogen ions and hydroxide ions?
Water is considered neutral because the number of hydrogen ions (H+) produced by the self-ionization of water (H2O -> H+ + OH-) is equal to the number of hydroxide ions (OH-) produced. This results in a balanced concentration of H+ and OH- ions, giving water a neutral pH of 7.
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.
How many molecules of hydrogen are produced if 13.05 g of Zn reacts with excess hydrochloric acid?
To determine the number of hydrogen molecules produced, you first need to find the moles of zinc reacting. Then, using the balanced chemical equation, you can determine the moles of hydrogen produced. Finally, convert moles of hydrogen to molecules using Avogadro's number (6.022 x 10^23 molecules/mol).
What will be the number of hydrogen and hydroxide in a PH of 6?
In a solution with a pH of 6, the concentration of hydrogen ions (H+) will be 10^-6 moles per liter. The concentration of hydroxide ions (OH-) in water is 10^-14 moles per liter at 25°C, so in a neutral solution, there would be the same number of hydroxide ions.
