Answer:
25,272
Explanation:
Multiply 9.0 x 108 = 972
Multiply 3.0 x 10 = 30 - 4 = 26
Lastly, multiply 972 x 26= 25,272

Answer:
Ethylene glycol
HOCH₂CH₂OH
Explanation:
For the molecules in the question, the viscosity will rise with the number of hydrogen bonds that can be formed.
A hydrogen bond is a week physical bond which is formed when hydrogen is found between atoms with high electronegativity (oxygen, nitrogen, fluorine):
O-H ··· O, N-H ··· O, N-H ··· O, O-H ··· N, F-H ··· F and so on.
Here we have have two compounds that can form hydrogen bonds (between themselves):
C) ethanol and D) ethylene glycol
Ethylene glycol have more hydroxide groups (-OH) than the ethanol so it will form more hydrogen bonds thus increasing its viscosity.
Answer:
Low density
Explanation:
The answer to this question is low density as Gases in general have low densities as their particles are very far apart. Their inter-molecular spaces are actually large. And The number of molecules per unit volume in a gas are small when we put them in comparisons with solids and liquids. That is why they have low densities.
I hope this answers your question.
