Explanation:
From the attached phase diagram, one can easily make out the phase in which water exists. Matter generally exists in three physical states which are solid, liquid and gas. Water is a unique compound that can exists in these three states at a given temperature and pressure.
From the attached phase diagram,
- point O is the triple point where the three phases of pure substance co-exists.
- The areas between the curves points at a single phase of matter. Y is a water vapor.
- The lines on the curve denotes two equilibrium phases. For example; X is a phase contain ice and melt water.

Adults have stem cells because they are needed to repair certain tissues in the body such as in the muscles, bone marrow, skin, teeth, heart, and liver, to name a few. Thus, they can develop into many different cell types and function to replace older and damaged tissues.
I looked on google cuz i was a lil stumped myself, and it looks like the answer is a. I couldnt find how to solve the equations, sorry
Answer:
16 mol O2
Explanation:
CO + 2 O2 -> 2 CO2
1 mol CO -> 2 mol O2
8 mol CO -> x
x= (8 mol CO * 2 mol O2)/1 mol CO
x= 16 mol O2
Answer:
Explanation:
molar volume=moles*given volume
for molar concentration we use two formulas molarity and molality
molarity=no of moles/volume
molality=no of moles/kilogram
