A key step in balancing chemical equations is correctly identifying the formulas of the reactants and products. For example, con

sider the reacti on between calcium oxide, CaO(s), and H2O(l)
to form aqueous calcium hydroxide. Write a balanced chemical equation for this combination reaction, having correctly identified the product as
Ca(OH)2(aq).

Answer:

CaO + H2O= Ca(OH)2

Explanation:

The rule of balancing chemical equation states that the total number of atoms an element on the right hand side, must equal the total number of atoms of the same element on the left hand side of the reaction equation. This rule is satisfied in the equation above. For example, there are two oxygen atoms at the RHS and two at the LHS.

Differentiate between Acidic radical and basic radical ​
Paladinen [302]

Explanation:

<em>Acidic</em><em> </em><em>radical</em><em> </em>

<em>Acid radical is the ion formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical.</em><em> </em>

<em>Basic</em><em> </em><em>radical</em><em> </em>

<em> The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical.</em>

Seawater has a ph of 8.1. what is the concentration of oh–?
lara31 [8.8K]
PH scale is used to determine how acidic or basic a solution is.
pH can be calculated as follows;
by knowing the ph we can calculate pOH
pH + pOH = 14
pOH = 14 - 8.1 
pOH = 5.9 
pOH is used to calculate the hydroxide ion concentration 
pOH = -log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 1.26 x 10⁻⁶ M
therefore hydroxide ion concentration is 1.26 x 10⁻⁶ M
