A.chloroplast
Chloroplasts performs photosynthesis during daylight hours
M₁V₁ = M₂V₂
(0.050M)*(10 mL) = (0.10M)*(x)
x = 5 mL
You would take 5 mL of the 0.10 M solution of HCl and add 5 mL of deionized water. Therefore, the total volume will be 10 mL and it will have a molarity of 0.050.
Answer:
Catod: K^(+), H2O
2H2O + 2e^(-) ---> H2 + 2OH^(-) reduction reaction
Anod: I^(-), H2O
2I^(-) ---> I2 + 2e^(-) oxidation reduction
2H2O + 2I^(-) ---> I2 + H2 +2OH^(-) ionic net reaction
Answer:
0.783 kg
Explanation:
You must make the conversions:
atoms of Pb ⟶ moles of Pb ⟶ grams of Pb ⟶ moles of Pb
Answer:
The answer is C: .588 M
Explanation:
[CaCl2] = mols CaCl2/Liters of solution
molar mass of CaCl2 = 110.98 g/ 1 mole (from periodic table)
800 mL/1000 mL = .8 Liters of solution
1)
52.3g CaCl2/ 110.98g = .47 mole
2)
.47 mole/.8 L = .589 M
So the answer is C
