A. 0.12 (mol/L)/s
rate = 1 x 10-2 • 2^2 • 3
Answer: 52.8 g of
Explanation:
To calculate the moles, we use the equation:
a) moles of octane
b) moles of oxygen
According to stoichiometry :
2 moles of
require 25 moles of
Thus 0.150 moles of
require=
of
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 2 moles of
give = 16 moles of
Thus 0.150 moles of
give =
of
Mass of
Thus 52.8 g of
will be produced from the given masses of both reactants.
Answer:
55g NH₄Cl / 100g Water
Explanation:
Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.
In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:
2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>
<em></em>

Answer:
Thallium is an isotope name that has a mass number of 201
Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic
