Answer:
You haven't given enough information, you have to tell us how many grams of which reactant are present, as well as the initial and final temperatures of the solution.
Explanation:
I would say B.HS(aq)+NiSO4(aq)
Answer:
The correct option is A
Explanation:
An independent variable is <u>a variable that is intentionally altered (directly or indirectly) and is not dependent on another variable</u> in the course of an experiment. Unlike the independent variable, the dependent variable depends or is presumed to depend on the altered independent variables.
From the explanation above, it can be deduced that the concentration of the catalase is the independent variable as it was intentionally altered (by using different concentrations) in the course of the experiment. The amount of oxygen given off is the dependent variable here
The dependent variable is 'Number of plants' which is the correct answer.
The independent variable is CO₂ levels in ocean water, however, the growth of plants in ocean water depends on the CO₂ levels. Higher CO₂ is level is conducive to the growth of plants.
Plants use CO₂ and water in photosynthesis to prepare food in the presence of light.
6CO₂ + 6H₂O + light energy = C₆H1₁₂O₆ + 6O₂.
Answer is: hydrogen cyanide (formonitrile).
Anion CN⁻ is cyanide. Cyanide <span>consists of a </span>carbon<span> atom </span>triple bonded<span> to a </span>nitrogen atom (<span>C≡N).</span>
Hydrogen cyanide is colorless, poisonous liquid, <span>also weakly </span>acidic. Salts<span> of the cyanide anion are called cyanides.</span>
