I don’t know I’m sorry I need points
Answer:
Explanation:
For this case we have to go through molecules to moles, from moles to grams and finally from grams to mg. The ratios that we have to take into account are:
-) <u>1 mol = 6.023x10^23 molecules</u>
-) The molar mass of <u>180.16 g = 1 mol</u>
-) <u>1 g= 1000 mg</u>
With this in mind we can do the calculation:
The answer would be D. I would guess but I could be wrong haha
Answer:
The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it.The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr). Microscopic view inside a bubble in boiling water.
Explanation:
Covalent compounds are those which are made up by sharing of electrons between them and the electronegativity of the elements which form covalent compounds are nearly same that is they are generally non-polar in nature whereas ionic compounds are formed by complete transfer of electrons from one element to the other and thus resulting in formation of ions of opposite charges that is cation (with positive charge) and anion (with negative charge). There is a large difference in electronegativity of the element involved in the formation of ionic compounds. They are held together by electrostatic force of attraction between them.
The conductivity of a substance is determined by the flow of electric charge. When the charged particles move that are present in the ionic compounds only in the conductivity apparatus they complete the circuit by the flow of electrons.
Hence, a conductivity apparatus test whether a solution has ionic or covalent substances in it as ions complete the flow of electrons to form a circuit.
