Answer:
pH = 2,4
Explanation:
pH is defined as a measure of acidity or alkalinity of a solution based on H⁺ concentration
The HCl dissociates in water thus:
HCl → H⁺ + Cl⁻
That means that moles of HCl are the same than H⁺.
0,35gHCl = 9,6x10⁻³ moles HCl ≡ moles H⁺
H⁺ molarity is: = 3,84x10⁻³M
As pH = -log [H⁺]
<em>pH = 2,4</em>
I hope it helps!

106.785 kPa, I believe this is correct!
Explanation:
Answer:
has two double C-C bonds
Explanation:
A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon.
If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.
Explanation:
When citric acid and baking soda react with one another, they change chemi- cally and form sodium ions, citric acid ions, carbon dioxide gas, and water. ... It also makes up the bubbles in carbonated drinks and is a gas we naturally exhale. Carbon dioxide gas is safe in the quantities produced in the activities.
Pure substance element I think
