In a titration when the number of moles of hydrogen ions equals the number of moles of hydroxide ions what is said to have happened?
When the number of moles of hydrogen ions equals the number of moles of hydroxide ions in a titration, it means that the solution has reached the equivalence point. At this point, the solution is neutral and the pH is typically around 7, indicating that the acid and base have reacted completely with each other.
How many moles of hydrogen are in 1.8 moles of quinine?
Quinine has the chemical formula C20H24N2O2. To determine the number of moles of hydrogen in 1.8 moles of quinine, we note that each molecule of quinine contains 24 hydrogen atoms. Therefore, in 1.8 moles of quinine, there are 1.8 moles × 24 moles of hydrogen = 43.2 moles of hydrogen.
For the reaction 2H2 plus O2 equals 2H2O how much water is produced when 2.5 moles of hydrogen react completely How do you do the problem?
2H2 + O2 ---------------> 2H2O for every 2 moles of hydrogen that reacts, 2 moles of water are produced, thus a 1:1 ratio of water produced to hydrogen reacted. So:- 2.5 moles of hydrogen reacted will produce 2.5 moles of water
What is the number of moles of hydroxide in the ash-solution?
An answer is not possible without any details.
Barium hydroxide contained 2.74g in 100cm of water titration of 20cm required 18.7cm of a hydrochloric acid solution for complete neutralization what is the molarity of the barium hydroxide?
To find the molarity of the barium hydroxide solution, first calculate the number of moles of hydrochloric acid used in the titration. Then use the stoichiometry of the reaction to determine the number of moles of barium hydroxide present. Finally, divide the moles of barium hydroxide by the volume of the solution in liters to get the molarity.

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.
How many atoms of hydrogen are in 0.180 moles of carbon hydroxide?
To find the number of atoms of hydrogen in a compound, you need to look at the chemical formula. In carbon hydroxide (CHO), there are 1 atom of hydrogen for each carbon and oxygen atom. In this case, there are 0.180 moles of CHO, so there are 0.180 moles of hydrogen atoms as well. To convert moles to atoms, you can use Avogadro's number (6.022 x 10^23) to find that there are approximately 1.08 x 10^23 atoms of hydrogen in 0.180 moles of carbon hydroxide.
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.
How many hydrogen atoms in 2 moles of hydrochloric acid?
In 2 moles of hydrochloric acid (HCl), there are 2 moles of hydrogen atoms. Since each molecule of HCl contains one hydrogen atom, multiplying the moles of HCl by Avogadro's number (6.022 x 10^23) gives the number of hydrogen atoms. Therefore, there are 1.204 x 10^24 hydrogen atoms in 2 moles of HCl.
How many moles in 20g of sodium hydroxide?
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
How many Moles of NaOH equals the moles of KHP?
When titrating NaOH with KHP (potassium hydrogen phthalate), the number of moles of NaOH will be equal to the number of moles of KHP at the equivalence point. This is because the reaction is stoichiometric, with one mole of NaOH reacting with one mole of KHP.
How do you find the number of moles of hydrogen there are in 3.5 moles of NH42 CO3?
To find the number of moles of hydrogen in 3.5 moles of (NH4)2CO3, first identify the stoichiometry of the compound. In (NH4)2CO3, there are two moles of hydrogen per mole of compound. Therefore, in 3.5 moles of (NH4)2CO3, there would be 2 * 3.5 = 7 moles of hydrogen.
How many moles of hydrogen are in 1.8 moles of quinine?
Quinine has the chemical formula C20H24N2O2. To determine the number of moles of hydrogen in 1.8 moles of quinine, we note that each molecule of quinine contains 24 hydrogen atoms. Therefore, in 1.8 moles of quinine, there are 1.8 moles × 24 moles of hydrogen = 43.2 moles of hydrogen.
Determine the number of hydrogen ions when you are given 2 moles of water?
4 moles of hydrogen atoms
What is true of the hydroxide and hydrogen ions in a solution of pH 7?
In a solution with pH 7, the concentration of hydroxide ions (OH-) equals the concentration of hydrogen ions (H+), with each being 10^-7 moles per liter. This represents a neutral solution where the two ions balance each other out.
For the reaction 2H2 plus O2 equals 2H2O how much water is produced when 2.5 moles of hydrogen react completely How do you do the problem?
2H2 + O2 ---------------> 2H2O for every 2 moles of hydrogen that reacts, 2 moles of water are produced, thus a 1:1 ratio of water produced to hydrogen reacted. So:- 2.5 moles of hydrogen reacted will produce 2.5 moles of water
