Answer:
O2
Explanation:
At standard temperature and pressure, oxygen is found as a gas consisting of two oxygen atoms, chemical formula O2.
Answer:
They both have the same number of atoms
Explanation:
quizlet
The side of each water molecule with the oxygen atom uncovered will be marginally negative.
The side of each water molecule with the hydrogen atoms uncovered will be marginally positive.
So the two Cl{-} particles will be pulled in to the biggest number of positive charges, which happen in the boxes on the upper right and lower left.
The two Na{+} particles will be pulled in to the biggest number of negative charges, which happen in the boxes on the upper left and lower right.
When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. It could be A I’m not sure if this helps.
Explanation:
As it is known that non-electrolytes do not dissociate. Therefore, molarity of such a solution is equal to the osmolarity of solution.
As, molar mass of ethanol = 46.07 g/mol
Therefore, no. of moles of ethanol will be calculated as follows.
No. of moles = 
=
=
mol
As, molarity is moles of solute in liter of solution. Hence, molarity of ethanol is as follows.
Molarity = 
= 
=
mol/L
Since, for the given solution Molarity = osmolarity
Thus, we can conclude that osmolarity of .00001 grams (0.1 mg%) of ethanol in 1 L is
osmol/L.
