The correct classification of the solutes are as follows:
<span>hydroiodic acid hi = strong electrolyte
calcium hydroxide ca(oh)2 = weak electrolyte
hydrofluoric acid hf = weak electrolyte
methyl amine ch3nh2 = weak electrolyte
sodium bromide nabr = strong electrolyte
propanol c3h7oh = non electrolyte
sucrose c12h22o11 = non electrolyte
Strong electrolytes are substances that completely ionizes in aqueous solution while weak electrolytes are those that partially ionizes. Non electrolytes are substances that cannot conduct electric charge since there are no ions in the solution.</span>
Answer is: pH <span>of a 0,01 M solution is 2.
c(HNO</span>₃) = 0,01 M = 0,01 mol/L.
pH = -log(c(HNO₃).
pH = -log(0,01 mol/L).
pH = 2.
pH<span> is a numeric scale used to specify the </span>acidity<span> or </span>basicity<span> of an </span>aqueous solution<span>. If pH is less than seven, than solution is acidic and if pH is greater seven, solution is basic, if pH is equal seven, solution is neutral.</span>
Chemical equation is the symbolic representation of chemical reactions.
Explanation
Chemical reactions are known as the reaction where two or more molecules or compounds react with each other leading to formation of product compounds along with either release or absorption of energy.
The symbolic representation of the processes occurring in a chemical reaction is termed as chemical equation.
The symbolic representation includes the reactants, products, external energy type and quantity of external energy and also about release of energy if occurs.
So the reactants are usually written in the left side of the chemical equation whereas on the right the products are written.
Both the sides are linked by a single headed arrow mark.
Some both the sides are linked by double heated arrow mark indicating the equilibrium chemical reaction.
Answer:
The correct option is (d).
Explanation:
It is given that,
1$ = 1500 pesos
We need to convert 360 pesos into dimes
We can convert 360 pesos to dollars as follows:
360 pesos is equal to $0.24
Also, 1 dollar = 10 dimes
We can covert 0.24 dollar to dimes as follows :
0.24 dollar = 10 × 0.24 dimes
0.24 dollar = 2.4 dimes
or
360 pesos = 2.4 dimes
Answer:
