Use the table to answer the following question. The table shows the pH of four body fluids and the resulting color when each is tested with red and blue litmus paper.
Body fluid
pH
Red Litmus
Blue Litmus
Blood
7.4
turns blue
no change
Bile
8.2
turns blue
no change
Saliva
6.8
no change
turns red
Gastric juice
1.7
no change
turns red
According to the data what kind of substance is gastric juice?
O A. it is a strong base since the blue litmus paper turns red and the pH is 1.7
o B. it is a weak acid since the blue litmus paper turns red and the pH is 1.7
O
C it is a weak base since the blue litmus paper turns red and the pH is 1.7
O D. it is a strong acid since the blue litmus paper turns red and the pH is 1.7

Which tool is least in predicting weather

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
