Question

How many joules of heat energy are needed to completely change 14.0 g of water to steam at the boiling temperature?

Answer 1

this question is a little different from your previous one.

use the formula \(q=x*\Delta H_{vap}\)

x = mass or moles, depending on what the units of \(\Delta H_{vap}\) are.

Answer 2

I don't understand this at all. especially since all Im given is 14.0 g

Answer 3

you'd have to be given \(\Delta H_{vap}\) or be expected to look it up in for book.

Answer 4

what does the x and q stand for in this

Answer 5

q is always heat energy

x=mass, or moles, it depends on what \(\Delta H_{vap}\) is in units of.
