Answer: option C. HF
Explanation: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. Fluorine is more electronegative than hydrogen so the electrons in the bond are more closely associated with the fluorine atom than with the hydrogen atom.
<u>Answer:</u> The molecular formula of compound is
<u>Explanation:</u>
We are given:
Empirical formula of compound = CHO
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :
We are given:
Mass of molecular formula = 180 g/mol
Mass of empirical formula = 29 g/mol
Putting values in above equation, we get:
Multiplying this valency by the subscript of every element of empirical formula, we get:
Hence, the molecular formula of compound is
Answer:
Structureless rocks like granite and other intrusive rocks tend to weather into characteristic rounded shapes through this process.
Explanation:
Answer:
Carbondioxide, water and ATP
Explanation:
The reaction is called aerobic respiration because oxygen from the air is needed for it to work.
If a liquid is heated it’s particles are given more energy and will move faster, however if it is cooled, it’s particles slow down and come closer together.
