Nitric acid in acid rain forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid. How do you write a balanced chemical equation for this reaction?
The first thing to do here is identify your reactants and your product. The problem tells you that gaseous nitrogen dioxide, $"NO"_2$ reacts with gaseous oxygen, $"O"_2$, and liquid...

How do you write a chemical formula for the following scenario: Nitric acid is a component of acid rain that forms when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid?
This is a synthesis reaction, also called a combination reaction, because two or more reactants produce a single product. You essentially have been given a word equation, which does not...

A chemist has one solution that is 50% acid. She has another solution that is 25% acid. How many liters of each type of acid solution should she combine to get 10 liters of 40% acid solution?
n liters from $50%$ acid solution and $10-n$ liters from $25%$ acid solution to produce 10 liters of 40% acid solution. $(ntimes0.50) + ((10-n)times0.25) = 10times0.40$ $0.50n + 2.5 -...

The gram formula weight of phosphoric acid is 98.00 g/mol, and the density of 85.0% phosphoric acid is 1.685 g/mL. Could you describe how to prepare 500 mL of a 1.0 M solution of phosphoric acid from 85.0% phosphoric acid?
You must make the following conversions: $"Volume of dilute acid" → "moles of H"_3"PO"_4 → "mass of H"_3"PO"_4 → "mass of conc. acid" → "volume of conc. acid"$ Here...

It is desired to prepare 4.0 M nitric acid from the available acid solution of strength 1.4 M & 6.8 M respectively. If the total volume of the 4.0 M nitric acid required to be prepared is 4 $dm^3$, calculate the volume of the 2 acid solutions to be mixed?
First we find the total moles of $HNO_3$ required: $c=n/v$ So $n=cxxv=4xx4=16mol$ Let volume of the 1.4M solution = $X$ Let volume of the 6.8M solution =$Y$ So we can...

Roman mixes 12 litres of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. How do you find the number of litres of 20% acid solution in the new mixture?
We can use the "volume × concentration" formula to work out the answer. $"Volume of 8 % acid + volume of 20 % acid = volume of 16 % acid"$...

What is the difference between a binary acid and a polyatomic acid?
The hydrogen halides, $HX$, are clasic binary acids. Oxoacids, e.g. $H_2SO_4$, $HNO_3$, $HMnO_4$ are their counterparts.

Which is the unsaturated acid: $"A. diacetic acid; B." H_3C(CH_2)_14CO_2H; "C. oleic acid; D. arachidic acid?"$
An unsaturated carboxylic acids contains only the $1^@$ of unsaturation. For instances, $"acetic acid"$, $"H"_3"CC(=O)OH"$, has formula $C_2H_4O_2$, i.e. $1^@$ of unsaturation. Both $"palmitic"$, and $"butyric acids"$ are saturated...

Identify the following compounds as strongly acidic, weakly acidic, weakly basic, strongly basic, or pH-neutral in water at $25^@ "C"$? $"Al"("NO"_3)_3$, $"C"_2"H"_5"NH"_3"NO"_3$, $"NaClO"$, $"KCl"$, $"C"_2"H"_5"NH"_3"CN"$
These are mostly straightforward, except for one. $"Al"("NO"_3)_3$ is strongly acidic because $"Al"^(3+)$ is a Lewis acid. It has an empty $3p_z$ orbital that accepts electron , making it...

Are all hydroxides basic? What makes a base basic, and an acid acidic?
Both $H_2SO_4$ and $HNO_3$ contain hydroxides....and yet these are STRONG acids.... And an acid is typically the hydroxide of a non-metal, whereas a base is typically the hydroxide of a...
