How do we represent the reaction between $"nickel(II) chloride"$ and $"sodium hydroxide"$ stoichiometrically?
You gots...... $NiCl_2(aq) +2NaOH(aq) rarr Ni(OH)_2(s)darr + 2NaCl$ All chemical equation CONSERVE (i) mass; and (ii) charge, and this is the principle of .......$"garbage in equals garbage out."$ The same...

How would you write a balanced chemical equation for the neutralization of sulfuric acid with potassium hydroxide? What is the name and chemical formula of the salt formed in this reaction?
This is because potassium has a valency of just 1+ and, since sulphate ions have a valency of 2-, two potassium ions are required per sulphate ion in order for...

A solution of iron(III)chloride is mixed with a solution of sodium hydroxide and reacts to yield solid iron (III) hydroxide and aqueous sodium chloride. What is the balanced chemical equation for this reaction?
Start by writing the unbalanced chemical equation that describes this double displacement reaction $"FeCl"_ (3(aq)) + "NaOH"_ ((aq)) -> "Fe"("OH")_ (3(s)) darr + "NaCl"$ In order to balance...

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...

A $25*mL$ volume of sodium hydroxide solution of $0.150*mol*L^-1$ concentration is stoichiometrically equivalent to a $15.0*mL$ of sulfuric acid. What is $[H_2SO_4]$?
$H_2SO_4(aq) + 2NaOH rarr Na_2SO_4(aq) + 2H_2O(l)$. And (ii) equivalent quantities of sodium hydroxide, $"Moles of NaOH"=25.0*mLxx10^-3*L*mL^-1xx0.150*mol*L^-1=3.75xx10^-3*mol$ Given the equation, we KNOW that there was a half an equiv of...

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...

Which for the following is considered a weak base?
A. Lithium hydroxide
B. Sodium hydroxide
C. Calcium hydroxide
D. Aluminum hydroxide
Thanks!
We gots $Al(OH)_3$...even tho this is still a basic species. $"Alumina"$, $Al_2O_3$, is an amphoteric oxide...that could act as an acid. The hydroxides of lithium, calcium, or sodium, all give...

What is the neutralization reaction between sulfuric acid and lithium hydroxide?
Is the given reaction stoichiometrically balanced? Two equiv lithium hydroxide reacts with one equiv sulfuric acid. If it had been barium hydroxide (and barium sulfate is sparingly soluble), how would...

How do you write the balanced neutralization equation for the reaction between acetic acid and sodium hydroxide?
acetic acid (ethanoic acid): $CH_3COOH$ $CH_3COOH = C_2H_4O_2$ sodium hydroxide: $NaOH$ neutralisation reactions always produce a salt and water. in this case, the salt is sodium ethanoate ($CH_3COONa, C_2H_3O_2Na$)...

A $38.74*mL$ volume of $0.50*mol*L^-1$ sodium hydroxide solution reaches a stoichiometric endpoint with $19.37xx10^-3*mol$ of sulfuric acid dissolve in $50.0*mL$ of solution. What is the concentration with respect to $"sulfuric acid"$?
$H_2SO_4(aq) + 2KOH(aq) rarr K_2SO_4(aq) + 2H_2O(l)$ This is an acid base reaction, and as you know sulfuric acid is diprotic. And this is probably the source of the confusion:...
