Answer:
The rate of a chemical reaction is directly proportional to the concentration. The rate of a chemical reaction increases as the substrate concentration increases and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.
Explanation:
The rate of a chemical reaction is directly proportional to the concentration.
The reaction rate increases with increasing substrate concentration, but levels off at a much lower rate. By increasing the enzyme concentration, the maximum reaction rate greatly increases.
Generally, the rate of a chemical reaction increases as the substrate concentration increases, and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.

Answer:</h3>
0.5 moles/L or 0.5 M
<h3>
Explanation:</h3>
- Molarity is the concentration of a solution in moles per liter.
- It is calculated by;
Molarity = Number of moles ÷ Volume
In this case;
Volume = 125 mL
Mass of sodium nitrate = 5.31 g
We are required to calculate the molarity of sodium nitrate
<h3>Step 1: Calculate the number of moles of sodium nitrate </h3>
Moles = Mass ÷ Molar mass
Molar mass of sodium nitrate = 84.9947 g/mol
Therefore,
Moles of NaNO₃ = 5.31 g ÷ 84.9947 g/mol
= 0.0625 moles
<h3>Step 2: Molarity of sodium nitrate </h3>
Remember;
Molarity = Moles ÷ Volume
Volume of NaNO₃ = 0.125 L
Therefore;
Molarity = 0.0625 moles ÷ 0.125 L
= 0.5 Moles/L or 0.5 M
Thus; the concentration of sodium nitrate is 0.5M
The Relative Formula Mass of carbon dioxide is 44. This may also be called the Relative Molecular Mass (RMM), since carbon dioxide is a molecule.
The plant that should be moved here to protect from malnourishment is plant 3. The correct option is C.
<h3>What is visible spectrum?</h3>
The visible light spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye. Simply put, this range of wavelengths is known as visible light.
The visible spectrum, also known as the optical spectrum, is the portion of the electromagnetic spectrum whose radiation consists of photons capable of sensitizing a normal person's human eye. The corresponding visible light radiation range is identified.
That being said, plant 3 is situated in front of a green stained glass window.
Plants have chlorophyll pigment that reflects back green light, making green light less effective for photosynthesis and causing them to die as quickly as if they were kept in the dark.
Thus, the correct option is C.
