Answer:
pH = pKa + log (33.7 mm / 26.3 mm)
Explanation:
Initial pH = 6.83
If we add a strong base, we expect that pH would be more alkaline
Initially we have: 60 mL . 0.50M = 30 mmoles of acid
Now, we add the base:
3.7 mL . 1.00 M = 3.7 mmmoles of base
Concentration of acid: 30 mmoles - 3.7 mmoles of base = 26.3 mm
Concentration of salt: 30 mmmoles + 3.7 mmoles of base = 33.7 mm
pH = pka + log (33.7 mm / 26.3 mm)
Information of pKa is missing
Answer:
35.0 kPa
Explanation:
As pressure decreases, the volume of a gas increases at a given temperature., so since the balloon got bigger, the new pressure must be less than 103kPa
Assuming the temperature does not change, use Boyles Law
P1V1 = P2V2
(103kPa) (1750L) = P2 (5150L)
P2 = (103)(1750) / 5150
C12H24O2 +17 O2-------->12CO2 + 12H2O
<h3>
Combustion:-</h3>
combustion is a chemical reaction that often involves the presence of oxygen and produces heat and light in the form of flames.
<h3>
Lauric acid:-</h3>
Lauric acid has a 12-carbon backbone and is a saturated medium-chain fatty acid. In addition to being a key component of coconut oil and palm kernel oil, lauric acid occurs naturally in a variety of plant and animal fats and oils.
White solid lauric acid has a little bay oil odour to it.
Lauric acid is a cheap, non-toxic, and easy-to-handle substance that is frequently employed in lab studies on melting-point depression. Because lauric acid is a solid at ambient temperature but a liquid at boiling temperatures, it can be used to test different solutes to determine their molecular weights.

The reaction of Mg Cl2 and KOH can be described as a double substitution type of reaction. This means the cations of the reactants are exchanged in places when the products are formed. In this case, the balanced reaction is expressed
MgCl2 (s) + 2KOH (aq) = Mhg (OH)2 (aq) + 2KCl (s)
