A scientist formulates the following hypothesis: If plants of the same species

Chemistry
1 answer:
Blababa [14]2 years ago
7 0

Answer:

Growth rate

Explanation:

The responding variable, also known as the DEPENDENT VARIABLE, is the variable that responds to changes or manipulations made to another variable (independent or manipulable variable) in the experiment. It is the measured variable of an experiment.

According to the hypothesis provided for this investigation, the scientist wants to determine if the amount of fertilizer plants of the same species receive will affect their growth rate when planted in the same condition. This shows that the independent variable is the amount of fertilizer to be used while the RESPONDING VARIABLE OR DEPENDENT VARIABLE is the GROWTH RATE OF THE PLANTS because it responds to the amount of fertilizer.

If you can continue to add more solute to a solution, the solution is said to be ____________________
Savatey [412]

Answer:

Unsaturated

Explanation:

In order to successfully answer this question, we need to think about the solubility of solutes in specific solvents, typically water.

  • A solution is considered to be unsaturated if at a given temperature and volume of water we may still add more solute and it will dissolve;
  • A solution is considered to be saturated if at a given temperature and volume of water we have a maximum amount of solute dissolved and trying to add more solute results in undissolved crystals that can be seen in the solution;
  • A solution is considered to be oversaturated (or supersaturated) i at a given temperature and volume of water we exceeded the maximum amount of a solute that could possibly dissolve.

In this case, if we can continue to add more solute to a solution and the solute dissolves, we may state that we are still at a point in which we have an unsaturated solution.

The rate constant for this second‑order reaction is 0.380 M − 1 ⋅ s − 1 0.380 M−1⋅s−1 at 300 ∘ C. 300 ∘C. A ⟶ products A⟶product
Sati [7]

Answer: 8.38 seconds

Explanation:

Integrated rate law for second order kinetics is given by:

\frac{1}{a}=kt+\frac{1}{a_0}

a_0 = initial concentartion = 0.860 M

a= concentration left after time t = 0.230 M

k = rate constant =0.380M^{-1}s^{-1}

\frac{1}{0.860}=0.380\times t+\frac{1}{0.230 }

t=8.38s

Thus it will take 8.38 seconds for the concentration of  A to decrease from 0.860 M to 0.230 M .
