The balanced chemical reaction is expressed as follows:
<span>CuCl2 (aq) + 2AgNO3 (aq) → 2AgCl (s) + CuNO32 (aq)
To determine the </span><span>concentration of copper(II) chloride contaminant in the original groundwater sample, we use the final amount of silver chloride that was produced from the reaction and the relation of the substances from the chemical reaction. We calculate as follows:
mmol AgCl = 6.1 mg AgCl ( 1 mmol / 143.35 mg ) = 0.0426 mmol
mmol CuCl2 = </span>0.0426 mmol AgCl ( 1 mmol CuCl2 / 2 mmol AgCl ) = 0.0213 mmol CuCl2
concentration of CuCl2 in the original water sample = 0.0213 mmol CuCl2 / 200.0 mL = 1.0638 x 10^-4 mmol / mL or 1.0638 x 10^-4 mol/L
Answer:
X
Explanation:
Assume your diagram is like the one below.
X represents a mitochondrion.
That's where the Tricarboxylic Acid Cycle converts a single glucose molecule into six molecules of CO₂.
W is wrong. It represents a vacuole, which can store both nutrients and waste products for later elimination.
Y is wrong. It represents the nucleolus, which plays a critical role in the synthesis of ribosomes.
Z is wrong. It represents the cytoplasm, which is where cell processes like glycolysis and protein synthesis take place.
Answer:
b. Magnetism (sorry im very late)
Explanation:
Intensive properties do not depend on size, no matter what it doesn't. For example, magnetism, density, melting and boiling points, and color. All of those support intensive property.
