Ph, Acids and Bases Quick Check
Which statement best describes the difference between a substance with a pH of 3.0 and a substance with a pH of 6.0? (1 point)
O The substance with the higher pH has twice as many hydrogen ions per volume of water.
The substance with the lower pH has twice as many hydrogen ions per volume of water.
The substance with the higher pH has 1,000 times as many hydrogen ions per volume of water. O
O The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
Answer: c
Explanation: 3.0 is 1,000 times as many ions
The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
for substance with pH = 3
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
for substance with pH = 6
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Sign an experiment.
A: John Smith has been hired by the city of Virginia Beach to investigate the recent increase in shark attacks off
the resort's coast. The resort has also heard from its guest recently an increased number of elephant seals that
are seen at the beach. Elephant seals are highly migratory and move with the seasons. He has a budget of
$40,000, a 25 foot boat, and three graduate student assistants to help him. A helicopter has also been donated by
a local television station, should he need one.
1. List 2 hypotheses John and his crew may have come up with for the recent shark attacks.
a. If
then
b. If
then
2. Pick one of the two hypotheses and determine the following:
a. Control Group:
b. Experimental Group:
c. Dependent Variable:
d. Independent Variable:
3. What type of data do you think John will collect (What will be the results of the experiment)?
4. What conclusions will John be able to make from the results of the experiment?
The answers to the questions required for the design experiment above are :
If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal. The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach. The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low). The Dependent variable : Number of shark attacks The Independent variable : The different number of elephant seals found. Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points. John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.
The Dependent variable is the measured variable is changes as the independent variables are tweaked.
Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

How would the loss of predators contribute to deforestation in the
jungle?
Answer:
Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.
