i think the answer is C3H8O
Hello!
The answer is Evaporation!
When you add enough heat to a liquid, it boils turning into a gas. This is called Evaporation
Answer: I believe C is your best answer
Explanation: The earth revolves around the sun in an elongated circle. Every year is one full “circle.” Due to the earth also having a tilt on its axis, one “side” of the earth is usually closer to the sun. So In the first quarter of the earth’s travel around the sun, it’ll be winter, then the next quarter, spring, followed by Summer halfway through and then Autumn/fall. Such can be compared to how the seasons each usually fill in about a quarter of your calendar. That was explained a bit confusing but I hope I helped, good luck!
The concentration of cell is less than that of the solution .
Hence the cell will be called as hypotonic and the solution will be called as hypertonic.
in order to balance the concentration on the two sides of cell (inside and outside in the solution) there will be movement of solvent particles (through semipermeable membrane ) from cell (lower concentration of solute) to solution (higher concentration of solute).
Thus cell will shrink.
Answer:
19.8 %
Explanation:
V% = ( V of solute \ 100 ml of solution ) ×100% =
the volume of the solute in 100ml solition = 20 ml
42.9 ml of solute ----------215 ml solution
× ----------- 100 ml solution
42.6 × 100 ml ÷ 215 ml
= 19.8 ml of solute
the V% = (19.8 ÷ 100) ×100% = 19.8%
