Answer:
The pressure in mmHg is 59.
Explanation:
Given data:
Pressure of air inside balloon = 0.78 atm
Pressure in mmHg = ?
Solution:
mmHg:
mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.
Symbol:
"mmHg"
Atmosphere (atm)
atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.
1 atm = 760 mmHg
Inorder to convert the atm into mmHg we will multiply the given atm value with 760.
0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg
59 mmHg or 59
Answer: Water, alcohols, aldehydes, and ketones.

Answer:
The correct option is the A
Explanation:
Like oxygen is more electronegative than hydrogen, it attracts electrons stronger than hydrogen. Therefore the two covalent bonds are polar.
The option b is incorrect because if oxygen and hydrogen had similar electronegativities, they would form no-polar bonds.
The option c is incorrect because oxygen is more electronegative than hydrogen (you can check that in a periodic table).
The options d and e are incorrect because the molecular size or hydrophilic don't influence the type bond.
Metallic I’m pretty sure. :)
