When an ice cube melts it is still water

yes it is still water

Explanation:

I don't really get your question, but I'm guessing your wondering if an ice cube is fully melted, is it still water? If that's it then yes, it's still a water liquid just in a different form.

Explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the ratio of the conjugate base to the acid required to attain the desired ph.
