Liquid oxygen boils at 1829 degree C Express the boiling poi

Liquid oxygen boils at -182.9 degree C. Express the boiling point of liquid oxygen in degree F -384.4 -352.4 -320.4 -297.2 -76.8 The oxidation number of iron in Fe_2O_3 is -2 +1 +2 -3 +3 The ground state condensed electron configuration of Ga is [Ar]4s^2 3d^10 4d^1 [Ar]4s^23d^11 {Kr]4s^2 3d^10 4p^1 [Ar]4s^2 3d^10 4p^1 [Ar]4s^2 4d^10 4 p^1 What volume (mL) of a concentrated solution of magnesium chloride (9.00 M) must be to 350mL to make a 2.75M solution of magnesium chloride? 107 350 50.0 2.75 45.0 The elements in groups 1 A, 7A, and 8A are called respectively alkaline earth metals, halogens, and chalcogens halogens, transition metals, and alkali metals alkali metals, halogens, and noble gases alkaline earth metals, transition metals, and halogens alkali metals, halogens, and noble gases

Solution

15)

C = (F-32)*5/9

-182.9=(F -32)*5/9

F = -182.9*9/5 +32

=-297.22

D is the right option
