Aflask filled with oxygen is heated from 5 degrees celsius to 30 degrees celsius. the starting pressure was 50 kpa, what is the final pressure? (be sure to convert from celsius to kelvin, add 273 to your celsius temperature to get the temperature to kelvin. ex. 0 degrees celsius id equal to 273 kelvin)

we need the questions , i may then you.

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 correct answer is:
