The answer should be D all of the above
pH scale is used to determine the acidity of a solution
pH is calculated using the H⁺ concentration
pOH scale is used to determine how basic a solution is
pOH is calculated using the OH⁻ concentration
pH and pOH are related in the following formula
pH + pOH = 14
pH = 3
pOH = 14 - 3
pOH = 11
pOH is calculated using the following formula
pOH = - log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = antilog(-11)
[OH⁻] = 1 x 10⁻¹¹ M
the [OH⁻] concentration of lemon juince is D) 1 x 10⁻¹¹ M
Answer:
Theoretical yield of C6H10 = 3.2 g.
Explanation:
Defining Theoretical yield as the quantity of product obtained from the complete conversion of the limiting reactant in a chemical reaction. It can be expressed as grams or moles.
Equation of the reaction
C6H11OH --> C6H10 + H2O
Moles of C6H11OH:
Molar mass of C6H110H = (12*6) + (1*12) + 16
= 100 g/mol
Mass of C6H10 = 3.8 g
number of moles = mass/molar mass
=3.8/100
= 0.038 mol.
Using stoichoimetry, 1 moles of C6H110H was dehydrated to form 1 mole of C6H10 and 1 mole of water.
Therefore, 0.038 moles of C6H10 was produced.
Mass of C6H10 = molar mass * number of moles
Molar mass of C6H10 = (12*6) + (1*10)
= 82 g/mol.
Mass = 82 * 0.038
= 3.116 g of C6H10.
Theoretical yield of C6H10 = 3.2 g
482VP I think is the correct answer.
Answer:
K = 351.3
Explanation:
The relationship between the Celsius scale and kelvin scale is;
K = 273 + C
Since the Celsius temperature = 78.3
The kelvin temperature is given as;
K = 273 + 78.3
K = 351.3
