PLEASE HELP ME IM STUC!! Mass Melting Point of Tin Melting Point of Lead
(kg) (°C) (°C)
1 W Y
2 232 327

Part 1: What will be the values of W and Y for 1 kg of each substance?
Part 2: Explain your answer for Part 1.

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.

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

i think it is true since you can test the answer and can use observations to complete it.
