As you have seen in this lab, the density of water is near 1 g/cm3. Anything with a density lower than this will float in water,

and anything with a higher density will sink. Imagine you are building a submarine. How could you be sure to have it sink and then rise?
Make sure its density is always above 1.0 g/cm3.

Make sure its density is always below 1.0 g/cm3.

Develop a way to adjust its density so that it can be above and below 1.0 g/cm3.

The third answer is the one you want. You have to have an adjustable density. All other things being equal, if the tanks you use for holding just water when filled with water will let the sub sink, because the sub is made of a dense metal like iron or steel.

If on the other hand you fill these tanks with air, the net density will be below one and the sub will rise.

Answer: C) develop a way to adjust its density so that it can be above and below 1.0 gram per cubic centimeter.

Explanation: Submarine is a kind of special ship that can float above and below water. We know that an object can only float over water when its density is less than the density of water and it would sink if its density is greater than the density of water.

A submarine has tanks in which water is filled if we want to sink it and the water from the tanks is taken out with the help of water pumps to rise the submarine. These water tanks in the submarine helps to adjust its density.

The over all density is increased by filling the water tanks to sink the submarine and the density is decreased by removing the water from the tanks to rise the submarine.

So, option third or C is correct.

What are the isomers of butanol​
Juliette [100K]

There are three other structural isomers of 1-butanol: 2-butanol (sec-butyl alcohol), 2-methyl-1-propanol (isobutyl alcohol), and 2-methyl-2-propanol (tert-butyl alcohol). 2-Butanol, or sec-butanol, or sec-butyl alcohol, or s-butyl alcohol, is a four-carbon chain, with the OH group on the second carbon.

Chemicals of this type: Ethanol

What does ph measure? 6. msg behaves as a buffer. what is a buffer? 7. if we are interested in understanding how msg behaves as
Ket [755]

1. Answer;

- pH of a solution is the measures of molar concentration of hydrogen ions in a solution.

Explanation;

-pH is a measure of how acidic/basic  a substance is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in a substance.

-The pH value states the relative quantity of hydrogen ions (H+) contained in a solution. The greater the concentration of H+ the more acidic the solution and the lower the pH.

2. Answer;

Buffer is a substance that minimizes change in concentrations of H+ and OH- in a solution.

Explanation;

-A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa.

-A buffer can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.

3. Answer;

By combining the two substances, we can analyze how the buffers react and stabilize the pH in the solution

Explanation;

- We found out that MSG was a buffer, and since it was a buffer more hydrogen ions is added to the solution. When we added it to the solution, it became a solid, which was what precipitated.

-There were a lot of Hydrogen protons floating around and with the MSG precipitate, we have all of these floating hydrogen and hydroxide ions. These hydrogens and hydroxide ions attach to the MSG, and the extra hydrogens would help to form the precipitate.
