it is number 4 heat and pressure during metamorphism
Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases. Moving down a group in the periodic table, the number of filled electron shells increases
A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L
B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L
Hoped this helped ( I believe it's right, sorry if it's not )
