A0.0733 L balloon contains 0.00230 mol of 12 vapor at a pressure of 0.924 atm
What is the temperature, in Kelvin, of the I2 in the balloon?
Express the answer using 3 significant figures.

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

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 cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
