<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds
will contain both metals and non-metals, or at least one polyatomic
ion. *Acids will always include the (aq) symbol beside the formula, and
the name will include the word acid.</span>
Your answer is Canada for sure I hope you make a 100 :))
Answer: 3.7 x10−6 Mole per dm^3
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
So, pH = - log(H+)
Since the solution has a pH of 5.43
5.43 = -log(H+)
To get hydrogen ion concentration, find the Antilog of 5.43
(H+) = Antilog (-5.43)
(H+) = 0.000003715
Then, 0.000003715 in standard form becomes 3.7 x10−6 M
Thus, the concentration of hydrogen ion in the solution is 3.7 x10−6 Mole per dm^3
An ELEMENT is a substance that cannot be broken down into other substances by ordinary chemical procedures. Some easy examples would be: <span>gold, iron, carbon, </span>hydrogen<span>, </span>oxygen<span>, nitrogen.</span>
