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.

<u>Solution</u> : Emperical Formula =
Emperical Formula - A formula that gives the simplest whole number ratio of atom in a compound.
In the question percentages are given then assume that the total mass is 100grams so that the mass of each element is equal to the percentage given.
Given : 80.0g Carbon
20.0g Hydrogen
First convert the given masses into moles.
Value of each mole divided by the smallest number of moles and then round off.
Moles ratio of the element are
This is the mole ratio of the elements and is repersented by the subscript in the emperical formula.
Emperical Formula =
The path taken by pollen as it fertilizes a plant would be:
anther ---> stigma ---> style ---> ovule
The fertilization process in plant starts by pollination. Pollen grains move from the anther of a flower to the stigma of the same or different flower. On the stigma, the pollen germinates and the cells of the pollen tube grows through the style to reach the ovule.
The generative cell of the pollen travel through the pollen tube to reach the embryo sac of the ovule. The cell divides by mitosis to form sperm cells and one of the sperm cells fertilizes the egg cell to form the zygote.
