Answer:
D. second order, 1/[A]t versus t
Explanation:
Since the power of the concentration is 2 in the rate law, it is a second order reaction. Also, for a second order reaction, the variables that would yield a straight line when graphed are 1/[A]t versus t
A) high ph and low ph
B) low and high ph
c) high and high ph
D) low and low ph
its b
A solution containing HCl, or Hydrochloric Acid, would likely have a low pH due to its acidic nature which greatly increases the amount of Hydronium ions in the solution and thus lowers the pH often below 7.
A solution containing HCl, or Hydrochloric Acid, would likely have a low pH. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14 with 7 as neutral. Since HCl is a strong acid, it will greatly increase the amount of Hydronium ions (H₃O⁺) in the solution, thus making the pH of the solution low, often below 7.

Answer:
The answer to your question is below
Explanation:
Question 2.
Answer: The molar mass is found by taking 2 x the molar mass of K, plus 1 x the molar mass of sulfur, plus 4 x the molar mass of oxygen.
Question 3.
molar mass H₂O₂ = (1 x 2) + (16 x 2)
= 2 + 32
= 34.02 g
Use proportions to find the number of moles
34.02 g of H₂O₂ ----------------- 1 mol
4 g ------------------ x
x = (4 x 1)/34.02
x = 4/34.02
x = 0.1175 ≈ 0.118 moles
Answer: 0.118 moles
c. 480 g/cm3
b. 270 g/cm3
d. 48 g/cm3
