A. Filtration
This is because of the layers of Filter it goes through to make sure it is pure.
Answer:
pH = 4
Explanation:
pH is a base 10 logarithmic scale
1000 = 10^3
7 -3 = pH = 4
Answer:
this is true about respiration (inhalation and exhalation)
Explanation:
inhalation is the exchange of gas from the environmental oxygen to the oxygen in the tissues.
while Exhalation is the gas exchange of CO2 with O2 (the CO2 is exhales from high concentration to the environment of low concentration.
Answer:
M₂ = 0.08 M
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 0.500 M
Final volume = 150.0 mL
Final molarity = ?
Solution:
Formula:
M₁V₁ = M₂V₂
0.500 M × 25.0 mL = M₂ × 150.0 mL
M₂ = 0.500 M × 25.0 mL / 150.0 mL
M₂ = 12.5 M.mL /150.0 mL
M₂ = 0.08 M
