The temperature of a sample of iron with a mass of 10.0g changed from 50.4C to 25.0C with the release of 47 joules of heat. What is the specific heat of iron?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
