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.
The animals have to adapt to their new environment meant and continue mating so they do not go extinct
Find a fruit you think is the one that contains the most vitamin C.
For example: kiwi
Answer: I hypothesize that kiwi contains the most vitamin C
Then after that you test your hypothesis by comparing fruit that contains vitamin C in an experiment.
Answer:
0.2788 M
1.674 %(m/V)
Explanation:
Step 1: Write the balanced equation
NaOH + CH₃COOH → CH₃COONa + H₂O
Step 2: Calculate the reacting moles of NaOH

Step 3: Calculate the reacting moles of CH₃COOH
The molar ratio of NaOH to CH₃COOH is 1:1.

Step 4: Calculate the molarity of the acetic acid solution

Step 5: Calculate the mass of acetic acid
The molar mass of acetic acid is 60.05 g/mol.

Step 6: Calculate the percentage of acetic acid in the solution

Answer:
11.9 moles Cl₂
Explanation:
To find the number of moles, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.
P = 33.3 atm R = 0.0821 L*atm/mol*K
V = 11.5 L T = 120. °C + 273.15 = 393.15 K
n = ? moles
PV = nRT
(33.3 atm)(11.5 L) = n(0.0821 L*atm/mol*K)(393.15 K)
382.95 = n(0.0821 L*atm/mol*K)(393.15 K)
382.95 = (32.2776)n
11.9 = n
