Explain why “advancing water contact angles are more sensitive to the hydrophobic property of a surface whereas receding water contact angles are more sensitive to the hydrophilic property of a surface”.

Answers

Answer 1

Answer: Surface tension has a more complicated effect on capillary pressure: on the one hand, capillary pressure is directly proportional to surface tension. High surface tension liquids, on the other hand, typically have higher contact angles, which lowers capillary pressure.

If the cell was a city, what would the city have inside it for it to function as a cell?

Explanation:

The cell membrane can be a fence or wall around the city because it controls what enters and leaves the cell, and separates the cell from the outside.

The nucleus could be the city hall because it  protects DNA and controls the cell (city)

The mitochondria could be the greenhouse because it makes ATP energy from sugar + 02

The chloroplasts could be a farm or garden because it is where photosynthesis takes place and makes energy + sugar from sunlight

The ribosomes could be the factory to make stuff because it makes proteins

The endoplasmic reticulum could be a kitchen or restaurant because it helps finish proteins, and makes membranes.

The golgi apparatus could be the postal office because it finishes packages and ships proteins

The vacuoles could be a water tank because it storages water

lactase is an enzyme that breaks down a sugar found in dairy products known as lactose. Some people are lactose intolerant, and this can be due to not having enough lactase production. People who are lactose intolerant may not feel well after eating foods containing lactose. Illustrate the scenario and describe the relationship between the substrate and enzyme.

Answers

Answer

If people with lactose intolerance eat dairy products, the lactose from these foods pass into their intestines, which can lead to gas, cramps, a bloated feeling, and diarrhea.

Some people can have small amounts of dairy without problems. Others have a lot of stomach trouble and need to avoid all dairy products. Many foods, drinks, and digestive aids are available to help manage lactose intolerance.

A chemical reaction produces a molecule in which all of the atoms have a stable configuration. Which molecule could be the product of the reaction?

(1 point)

SiO

PH3

MgBr

KCl2

Answers

The product of this reaction is PH3. All of the atoms in PH3 have a stable configuration.

According to the octet rule, atoms are stable when they have two or eight electrons around their outermost shell. A stable configuration is one in which the outermost shell is fully filled with eight electrons.

The reason behind chemical combination is to enable atoms attain this stable configuration. If we look at the compound, PH3, we will notice that phosphorus has eight electrons around its outermost shell while each hydrogen atom has two electrons around its outermost shell hence  all of the atoms have a stable configuration.

Need help, please teach me how to solve it!

Answers

Answer:

See below

Explanation:

2C2H6 + 7O2 = 4CO2 + 6H2O

2C2H2 + 5O2 = 4CO2 + 2H2O

A lot of this is trial and error.  I start from left to right.  For the first reaction, you had

C2H6 + O2  =  CO2  +  H2O

You have 2 carbons on the left so you can try adding a 2 in front of the carbons on the right and keep going from there.  Now you have

C2H6  +  O2  =  2CO2  + H2O

You now have 2 C on each side.  C2 is the same as 2C.

The next step is to look at the hydrogens on the left.  You have 6 so you need 6 on the right.  You can add a 3 in front of the H on the right.  The H already has a subscript of a 2 so having the 3 in front will now make it 6H.  You now have this

C2H6  +  O2  =  2CO2  +  3H2O

So your C are equal (2 on each side) and your H is equal (6 on each side).  All that is left is the O.  So far you have 2 on the left but you have 7 on the right (4 from the 2CO2 and 3 more from 3H2O).  Since you have an even number on one side and an odd number on the other, there is no way to make this work.  So it's time to start over.

My next step was to put a 2 in front of C2H6 and keep going as we did above.  Start with this

2C2H6   + O2  = CO2  + H2O

You have 4 C on the left.  So you need to add a 4 in front of CO2 to get 4 C on the right.  Now you have this

2C2H6  +  O2  =  4CO2  +  H2O

Now on the left you have 12 H (2 in front times the 6 subscript on the H).  You need to have 12 on the right.  We can get that by putting a 6 in front of the H2O ( again the 6 in front times the 2 subscript of the H is 12 total).  You have this now

2C2H6  +  O2  = 4CO2  +  6H2O

You now have 4 C on both sides, 12 H on both sides.  All that is left now is the O.

On the right side, you have a total of 14 ( 8 from the 4CO2 and 6 from 6H2O).  So you'd need to add 7 in front of the O2 to make it 14.

You're done.  4 C on both sides, 12 H on both sides and 14 O on both sides.

The second equation I just did the same process.
