It's because hydroxyl group is polar and it can dissolve polar compounds but the CH part of the molecule is nonpolar and it can dissolve nonpolar compounds.

When an experiment is repeated and the new results are different from the original results, what could you assume to be true?

goldenfox [79]

Answer:

C since however many times you repeat an experiment, it should give the exact same results or it wouldn't be accurate enough. ex if you measure a liquid to be 77ml in USA, it should give the same when measured in Germany, same with repeating experiments.

Which of the following is a proton donor. a. Bronsted-Lowry Base 6 Bronsted-Lowry Acid c. Lewis Acid d. Lewis Base

Margarita [4]

Answer:

Bronsted-Lowry acid

Explanation:

Bronsted-Lowry Base -

According to Bronsted-Lowry theory of acids and bases:

Acids are those substances which donate proton in the solution whereas bases are those substances which accept proton in the solution.

Consider an example,

$HCO_3^{-} + HOH\; \rightarrow H_2CO_3 + OH^{-}\\$

HCO3- behave as base as it accepts proton in the reaction whereas HOH behaves as acid as it releases proton.

According to Lewis theory of acids and bases:

Acids are electron acceptor and bases are electron donar. Acids are generally electron deficient species whereas Lewis are chemical species having lone pair of electrons.

For example, AlCl3 is behave as Lewis acid because of being electron deficient species.

NH3 is a Lewis base because of presence of lone pair of electrons.

Therefore, among given options, Bronsted-Lowry acid is the correct option.

The air pressure inside a balloon is 0.78 atm. What is this

Troyanec [42]

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
