Which bond is a very strong dipole-dipole force?
A. A covalent bond
B. An ionic bond
C. A hydrogen bond
D. A metallic bond

Answers

Answer 1

Answer : C. A hydrogen bond

Explanation:

Answer 2

Answer:

A. covalent bond

Explanation:

dipole-dipole interaction results from difference in electronegativity , eg H-F where Fluorine has strong electronegativity but Hydrogen has less electronegativity. hence the bond has dipole moment towards F atom.

Explanation:

The number of atoms of potassium can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 1.65 × 6.02 × 10²³

Rosa lives in New York City, which has an average altitude of 33 feet. When she is at home, it takes her 10
minutes to cook noodles in boiling water. She decides to go on a camping trip to Mount McKinley. Her
campsite is located 11,000 feet above sea level. Write the answer to each.
A) Where will the atmospheric pressure be higher: at her home or her campsite?

B) Where will the boiling point be higher?

C) Will the noodles cook faster, slower, or at the same rate at her campsite than home?

Answers

Answer:

Home

Home

Slower

Explanation:

A liquid starts changing its phase to gas when the two pressures become the same i.e., vapor and atmospheric.

At a higher altitude the atmospheric pressure lowers so little amount of heat is required for the vapor pressure of water to equalize with the atmospheric pressure at a higher altitude.

The pressure at the Rosa's home will be higher and lower in the campsite.

The boiling point will be higher at her home.

As the boiling point is lower in the campsite the water used in cooking noodles will evaporate faster this may lead to the noodles being under cooked. The water may evaporate before the noodles have cooked. So, the noodles will cook at a slower rate at the campsite and faster in her home.

A. The atmospheric pressure at Rosa's home is higher than her campsite.

B. The boiling point of water at Rosa's home is higher.

C. The noodles will be cooked faster at Rosa's home compared to at the campsite

A. The pressure has been the force that has been exerted by the molecules against each other, The higher altitude has lesser air molecules, which resulted in the lower pressure.

Since the pressure at 33 feet has been higher as than the pressure at 11,000 feet altitude, the atmospheric pressure at Rosa's home is higher than her campsite.

B. The boiling point has been the temperature at which liquids have been converted to gases. With the decrease in atmospheric pressure, there has been a lowering in the boiling point as well.

The atmospheric pressure at Rosa's home is higher compared to her campsite. Thus, the boiling point of water at Rosa's home is higher.

C. The lower atmospheric pressure at the campsite has been responsible for the lower boiling point of the temperature, This implies that water has converted to steam at lower temperatures. The lower temperature of water requires more time for the noodles to be cooked.

Thus, the noodles will be cooked faster at Rosa's home compared to at the campsite.

Explanation:

Brian is making a cake for his friend's birthday. He combines the ingredients for the cake and then pours the batter into two pans and bakes them for 45 minutes in the oven. While the pans are in the oven, he combines butter, sugar, and milk and mixes them together to make the icing. What type of changes created the cake and the icing?

A. Both the icing and the cake are formed by physical changes.
B. Both the icing and the cake are formed by chemical changes.
C. The icing is formed by a chemical change and the cake is formed by a physical change.
D. The cake is formed by a chemical change and the icing is formed by a physical change.

Answers

Answer:

it’s D.The cake is formed by a chemical change and the icing is formed by a physical change

Explanation:

It’s because when the cake was baking there was nothing physical about it so it was a chemical change the icing is formed by a physical change because all you did was mix three ingredients together

The type of changes that created the cake and the icing is;

Option D; The cake is formed by a chemical change and the icing is formed by a physical change.

 

This is about understanding type of changes in chemistry.

Physical change is defined as a change that affects the form of a compound or element but it doesn't affect its' chemical composition.Meanwhile, chemical change is defined as a change that affects the composition of a compound and a new substance is formed.

Now, for brian's cake he has combined raw ingredients into two pans and bakes the cake. For the cake to be baked, it means the ingredients mixed have changed from liquid to solid and also a new substance has been formed. Thus, we can say that the cake was formed from chemical change.

Meanwhile, the icing was formed by physical change because it did not undergo any chemical process and no new substance was formed as only butter, sugar and milk were mixed together.
