Answer:
The concentration would be; 0.0038 μgmL
Explanation:
Half life, t1/2 = 68 minutes
Initial Conc. [A]o = 0.12/μgmL
Final Conc [A] = ?
Time. k = 340 minutes
ln[A] = ln[A]o - kt
t1/2 = ln2 / k
k = 0.693 / t1/2 = 0.693 / 68 = 0.01019
ln[A] = ln (0.12) - 0.01019 (340)
ln[A] = -2.1203 -3.4646
ln[A] = -5.5849
[A] = 0.00375 ≈ 0.0038 μgmL

Hello!
The substances, ordered according to their dissolving time in water, are the following
Sugar Cubes > Granulated Sugar > Powdered Sugar
The difference between these substances is the degree of order. According to collision theory, for a substance to be dissolved, successful collisions between solvent molecules and solute molecules need to happen. as molecules are more ordered, successful collisions are less likely to happen, because atoms are fixed into a crystalline structure.
When the molecule is less ordered, successful collisions are more likely to occur, as the atoms can be impacted from different sides and aren't fixed into a given position.
As the degree of order increases, the dissolving time in water will be higher too, as more time would be required for successful collisions to happen. The most ordered substance is sugar cubes, followed by granulated sugar and powdered sugar, and that order is the same as the order for dissolving time.
Have a nice day!
The correct answer is H20.
In a chemical reaction, there are always two sides, the reactant side and the product side. The reactants are the elements that are reacting together. They are always written at the left side of a chemical equation, with a plus sign written in between two elements. The products are the new compounds that are formed from the reaction of reactants. They are always written at the right side of a chemical equation and a plus sign is used to join them if they are more than one. An arrow pointing to the products usually connect the two side of the equation. For the question give above, the reactant are CH4 and O2 and the products are CO2 and H2O.
