V = nRT/P
V = 0.685 mol*(.0821 L*atm/K*mol)*273 K/1 atm
Answer:
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration!
The answer with this question you could use the characteristic properties you could say it’s a liquid or the substance in the fluid state of matter having no fixed shape but a fixed volume the example would be water. Solid gas you can include melting point boiling point whether it’s an element or a pure substance.

Answer: The chemical formula for the formula given in the image is .
Explanation: There are many ways in which a model can be represented:
- Molecular Formula
- Ball and Stick formula
- Expanded Formula
- Condensed Formula
- Skeletal Formula
This molecule is represented by the Expanded Structural Formula and by seeing in the image we can count the number of each element present.
Number of Carbon atoms present = 4
Number of Hydrogen atom present = 9
Number of Oxygen atom present = 2
Correct representation for this will be .
