oxidizing agent

Question 6

Answer 6

oxidized

Question 7

Answer 7

true

Question 8

draw phase diagram and label points

Question 9

normal melting point is

Answer 9

solid <-> liquid

Question 10

critical point

Answer 10

cant distinguish gas from liquid

Question 11

normal boiling point

Answer 11

liquid <-> gas

Question 12

triple point

Answer 12

all three phases existing at equilibrium

Question 13

difference between geeral phase diagram and water phase diagram is

Answer 13

the slope of the line conncecting solid and liquid states in water diagram is negative rather than positive. Solid state is less dense than liquid state for water (ie ice floats)
