Potassium is a very flammable metal if it comes in to contact with water. As it burns with the water it creates potassium hydroxide ($KOH$) If you separate the potassium out from 50 grams of $KOH$, how many grams of potassium would you have?
$"Moles of potassium hydroxide"$ $=$ $(50*g)/(56.11*g*mol^-1)$ $"Mass of potassium metal"$ $=$ $(50*g)/(56.11*g*mol^-1)xx39.10*g*mol^-1$ $~=$ $??g$

What is the name of the salt product formed from a neutralization reaction between butanoic acid and sodium hydroxide?
the net ionic equation for neutralisation is $H^+ + OH^(-) rarr H_2O$. this is because the hydrogen ion dissociates from the acid, and the hydroxide ion dissociates from the metal...

What is the formula for this reaction: Sulfuric acid reacts with potassium hydroxide to produce potassium sulfate and water?
This is an example of a double replacement (double displacement) reaction. This type of double replacement is called a reaction since an acid and a base react and one of...

What mass of $"potassium sulfate"$ would result from the reaction between excess $"sulfuric acid"$ and $"potassium hydroxide"$?
We need a stoichiometric equation to represent the reaction: $H_2SO_4(aq) + 2KOH(aq) rarrK_2SO_4(aq) +2H_2O(l)$ And thus moles of potassium sulfate is equivalent to half the number of moles of potassium...

The balanced equation shows the reaction between aluminium hydroxide and hydrochloric acid to form aluminium chloride and water: Al(OH)3 + 3HCl = AlCl3 + 3H2O. 1 mole of aluminium chloride was formed, what mass of aluminium hydroxide was formed?
I'll assume you mean what mass of aluminum hydroxide reacted. We can use the coefficients of the equation to determine the number of moles of $"Al(OH)"_3$ that react, knowing that...

In the neutralization of sulfuric acid with sodium hydroxide, the theoretical yield from 6.9g of sulfuric acid is 10g. In a synthesis, the actual yield is 7.2g. What is the percentage yield for this synthesis?
And thus for this example $%"Yield"$ $=$ $(7.2*g)/(10*g)xx100%$ And we don't even need a calculator......... Most of the time, we write a stoichiometric equation, that shows the molar equivalence between...

Sulfuric acid has a molar mass of 98 g/mol. In the laboratory there is 100 mL of a 0.10 M sulfuric acid solution. How much water needs to be added to this volume to prepare a solution containing 4.9 g/L of sulfuric acid?
Your strategy here will be to use the volume and molarity of the initial solution to determine how many moles of sulfuric acid it contains use the...

Keeping in ming Arrhenius theory, write balanced chemical equations for:
a) Aqueous hydrobromic acid and potassium hydroxide
b) Aqueous sulphuric acid and barium hydroxide.?
The Arrhenius Theory of categorizes substances that produce hydrogen cations in solution, $"H"^(+)$, as acids and substances that produce hydroxide anions, $"OH"^(-)$, in solution as bases. For the first...

How do we represent the neutralization of sulfuric acid by sodium hydroxide in a stoichiometrically balanced chemical equation?
When you write or consider a chemical equation, the two things you must ask yourself are (i) is mass balanced?, and (ii) is charge balanced? If they are not then...
