Answer:
a,b,e,f,g
Explanation:
Hydrogen bonding is an intermolecular force of attraction between two molecules. It is a special type of dipole-dipole attraction.
In hydrogen bonding, the hydrogen on one molecule binds with an electronegative atom on another molecule usually oxygen, nitrogen and fluorine.
The simple electrostatic attraction leads to strong intermolecular interaction between two molecules.
For the formation of hydrogen bond, a hydrogen atom must be bonded to more electronegative specie usually N, O and F
In H₂O and H₂O₂ ; hydrogen bonds with Oxygen
CH₃NH₂; hydrogen is attached to nitrogen
HF; hydrogen is attached to fluorine
CH₃OH; hydrogen is attached to oxygen
Answer:
3500
Explanation:
well 1 liter is equal to 1000 cubic centimeters so multiply that by 3.5 and you get 3500
Answer:
growth of plants
Explanation:
The variable which changes on its own is called the independent variable and the variable which changes according to the changes in the independent variable is called the dependent variable.
Here the growth of the plants is observed under light of different colors. So, Suzie is has placed 5 ferns and placed them under different color lights. She also keeps the other factors such as amount of water the plants receive the same. She measures the different color lights have on growth of the plants.
Hence, here the dependent variable is the growth of the plants and the independent variable is the color of the lights.
It'd be a physical change. This is because it's a change in the state of matter and not altering the chemical structure of water
On the first one it is supposed to be 18. when you have a +1 charge you subtract it once. how i got 18 tho was from the protons. there was 19 so i subtracted that with 1 and got 18. hope that helped! :)
btw i’m not the best at explaining, i’m sorry :/
