Answer:
we know that
if a dilation produces a smaller figure
then
0< scale factor <1
so
case A) -2------> the scale factor must be a positive number
case B) 1/3----> 0< 1/3 <1---> is a possible scale factor
case C) 1------> this scale factor does not not produce a smaller figure, it produces the same figure
case D) 4----> this scale factor produces a larger figure
the answer is
1/3

The pH of the substance is 3.3 which is acidic.
<h3>What is pH?</h3>
The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.
Given the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we use the formulae
ph = –log[h+]
plugging in thge value of h+ as 5. 0 × 10–4 moles per liter we have:
pH = –log{5. 0 × 10–4 ]
pH=3.3
