How many moles of sodium hydroxide are formed when 46 g of sodium react with water?
First construct a a balanced equation for the reaction :
2Na + 2H2O --> 2NaOH + H2
From the equation, we know that the ratio of Sodium(Na) to the ratio of Sodium Hydroxide(NaOH) is the same.
Ar of Na = 23g/mol
Number of moles = mass / Ar = 46g / 23g/mol = 2mol (moles of Na used)
Since ratio of Na to NaOH is the same, therefore there are also 2 moles of NaOH formed.

Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
What is the name of the precipitate formed when barium chloride react with sodium hydroxide?
The precipitate formed when barium chloride reacts with sodium hydroxide is barium hydroxide (Ba(OH)2).
What salt is made when sodium hydroxide and hydrochloric acid react?
Sodium chloride is formed when sodium hydroxide and hydrochloric acid react. This is a neutralization reaction where the sodium hydroxide (a base) and hydrochloric acid (an acid) combine to form a salt (sodium chloride) and water.
What is the balanced equation for sodium hydroxide and copper III chloride?
The balanced chemical equation for the reaction between sodium hydroxide and copper(III) chloride is: 2NaOH + 3CuCl3 → 3Cu(OH)3 + 6NaCl This equation shows that two moles of sodium hydroxide react with three moles of copper(III) chloride to produce three moles of copper(III) hydroxide and six moles of sodium chloride.
What is the product of sodium hydroxide and copper sulfate?
The reaction between sodium hydroxide and copper sulfate forms copper hydroxide and sodium sulfate. Copper hydroxide is initially formed as a blue precipitate, which can further react to form copper oxide upon heating.
How many moles of sodium hydroxide will react with 17 moles of sulfuric acid?
In the acid-base reaction where sodium hydroxide and sulfuric acid react, the formula is: H2SO4 + 2NaOH --> Na2SO4 + 2H2O. The coefficients shown are necessary to uphold the law of conservation of mass. So, if you have 17 moles of sulfuric acid, you will need twice as many moles of sodium hydroxide, so the answer is 34 moles NaOH.
Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
What is the name of the precipitate formed when barium chloride react with sodium hydroxide?
The precipitate formed when barium chloride reacts with sodium hydroxide is barium hydroxide (Ba(OH)2).
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.
What salt is made when sodium hydroxide and hydrochloric acid react?
Sodium chloride is formed when sodium hydroxide and hydrochloric acid react. This is a neutralization reaction where the sodium hydroxide (a base) and hydrochloric acid (an acid) combine to form a salt (sodium chloride) and water.
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.
What is the balanced equation for sodium hydroxide and copper III chloride?
The balanced chemical equation for the reaction between sodium hydroxide and copper(III) chloride is: 2NaOH + 3CuCl3 → 3Cu(OH)3 + 6NaCl This equation shows that two moles of sodium hydroxide react with three moles of copper(III) chloride to produce three moles of copper(III) hydroxide and six moles of sodium chloride.
When sodium chloride and hydrochloric acid react then why sodium hydroxide do not formed?
The reaction is: NaOH + HCl = NaCl + H2O HCl and NaCl cannot react, the anion is the same.
What is the product of sodium hydroxide and copper sulfate?
The reaction between sodium hydroxide and copper sulfate forms copper hydroxide and sodium sulfate. Copper hydroxide is initially formed as a blue precipitate, which can further react to form copper oxide upon heating.
What is the balanced equation for the reaction between sodium and water to produce sodium hydroxide and hydrogen gas?
The balanced equation for this reaction is: 2Na + 2H2O -> 2NaOH + H2. This means that two moles of sodium react with two moles of water to produce two moles of sodium hydroxide and one mole of hydrogen gas.
What does sodium hydroxide and sodium sulfate react to form?
Sodium hydroxide and sodium sulfate don't actually react.
How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen 4Na OËÃ æ 2NaËÃO?
When 4 moles of sodium react with oxygen, 2 moles of sodium oxide are produced (according to the balanced equation). Therefore, when 10 moles of sodium react, 5 moles of sodium oxide will be produced.
