A sample of 4.5 moles of an unknown gas occupies a volume of 1.6L at 23.2atm, what is the ideal temperature in °C for this sample of gas?

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

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

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
