B and C will tend to have a negative charge.
Answer:
A difference of 1 would mean there is either x10 more or less depending on where you are starting.
Explanation:
The pH of 3 differs from 4 because the acidity of 3 is 10x higher than that of 4. This is due to how the scientific notation of 3 in relation to pH is 10x^-3 while that of 4 is 10^-4 so in terms of the stronger acid that would be the one with the pH of 3.
Heat flows from our body to iron
(6.0×10^4) = 60,000
(3.1×10^-1) = 0.31
60,000 × 0.31 = 18,600
