Explanation:
The reaction between sulfuric acid, H2SO4 , and the base sodium hydroxide, NaOH , is a neutralization reaction. Na2SO4 is the salt sodium sulfate. ... For example, the reaction you've chosen is an acid-base reaction (also known as a neutralization reaction).
Answer:
2,54x10² mmHg
Explanation:
To solve this problem you can use Clausius-Clapeyron equation that serves to estimate vapor pressures or temperatures:
Where:
P1 is 1,00x10² mmHg
ΔHvap is 39,3 kJ/mol
R is gas constant 8,314x10⁻³ kJmol⁻¹K⁻¹
T1 is 34,90°C + 273,15 = 308,05 K
T2 is 54,81°C + 273,15 = 327,96 K
Thus:
Thus, P2 is <em>2,54x10² mmHg</em>

Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M
Usually the controlled experiment is the one that is not tested so they look at the experimental experiment to find the differences. Sorry if this doesn't answer your question.
