Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration

The actual yield of a chemical reaction is generally <u>th</u><u>e</u><u>o</u><u>rotical</u><u> </u><u>yield</u><u>.</u>
A lower pH means that there are extra hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid. In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid.
The hydrated ion undergoes hydrolysis in solution producing `H3O+ . This occurs because the Be-O bond is very strong and so in the hydrated ion and it weakens the 0-H bond. Hence, there is a strong tendency to lose protons. For this particular reason, the aqueous solution of `BeCl_2` is acidic in nature.
<h3>Will baking soda decrease pH?</h3>
Baking soda, also regarded as sodium bicarbonate is naturally alkaline, with a pH of 8 When you add baking soda to your pool water, you will increase both the pH and the alkalinity, improving balance and clarity. Many industrial pool merchandise for elevating alkalinity utilize baking soda as their most important active ingredient.

Answer:
CN⁻(aq) + H⁺(aq) ⇒ HCN(aq)
Explanation:
Let's consider the following molecular equation.
NaCN(aq) + HI(aq) ⇒ NaI(aq) + HCN(aq)
HI is a strong electrolyte so it exists mostly in the ionic form. HCN is a weak electrolyte so it exists mostly in the molecular form.
The full ionic equation includes all the ions and the molecular species.
Na⁺(aq) + CN⁻(aq) + H⁺(aq) + I⁻(aq) ⇒ Na⁺(aq) + I⁻(aq) + HCN(aq)
The net ionic equation includes only the ions that participate in the reaction and the molecular species.
CN⁻(aq) + H⁺(aq) ⇒ HCN(aq)
