Please help! i have no clue!

1. Which of the solutions were acidic? Explain how you know.
2. Which of the solutions were basic? Explain how you know.
3. List the solution in order from most acidic to least acidic.

the 2 photos are the data i’ve collected and the scale i was given. please help me

1) lemon , stomach , grapes , tomatos , ammonia , milk

Explanation:

lemon has citric acid

grapes = malic acid

stomach = hydrochloric acid

tomatos = citric acid

ammonia ( it can be base or acid sometimes )

milk = lactic acid

2) soap , oven cleaner , bleach , ammonia , banana , baking soda , eggs

3) stomach acid , citric acid , lactic acid , malic acid ( ph scale )

the lower the ph the higher the acidity

so check the ph

note

PLEASE SUPPORT ME

I AM IN HIGH SCHOOL , BUT IT WAS DIFFICULT TO UNDERSTAND THE QUSETION YOU GAVE , THE ANSWERS  SHOWN IS BASED ON MY RESEARCH IF ITS WRONG PLEASE FORGIVE ME

THANK YOU

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

i think   the answer is c hope i'm right
