Answer with Explanation:

1. How will you make the soda sweetest ever?

What makes soda sweet is the "sucrose" that is being added in it. This is also known as "table sugar." It is a combination of "glucose" and "fructose." In order to make your soda the sweetest ever, make sure you add more sucrose.

Since most sodas are already supersaturated, you may heat the sugar and water in order to increase the process of dissolution. This will <u>prevent sugar from settling at the bottom</u> and will make your soda the sweetest ever.

2. How will you make the soda have lots of fizz?

Carbon dioxide makes the soda fizz. When it combines with water, it causes "carbonic acid" which is then forced inside the bottle of soda (under high pressure). In order to make the soda have lots of fizz, it is important to consider the <u>amount of sugar and salt that you add. </u>

Soda is not only supersaturated with sugar, but it is also supersaturated with carbon dioxide. Adding sugar and salt allows the carbon dioxide to hold on to the tiny bumps<em> (nucleation site) </em>of the sugar. This will then form bubbles. So, the more sugar and salt you put, the more fizz or bubbles will result.

3. How will you make the soda tart?

The soda tarts are made by using syrup. The best syrup to use is barrel-aged syrup (combining sugar and water and allowing it to rest for two days under room temperature). Next, combine the syrup with the lemon juice. If you are making cherry soda tart, then it is best to add cherry juice as well. Combine them all together in a cocktail shaker, then chill. <em>(Not sure about this, but I hope it helps.)</em>

The quantum numbers of six electrons are given bellow .Arrange them in order to increasing energies. (a) n= 4,l =2, m= -2, s= -1
krek1111 [17]

Answer:

e< d< b< c=f< a

Explanation:

Quantum numbers refers to values that exactly describe the energy of electrons within an atom or a molecule. Electrons are known to possess a set of four quantum numbers used in describing the energy state of such electron. These quantum numbers are solutions to the Schrödinger wave equation for the hydrogen atom.

In describing any electron within the atom, the relevant set of four quantum numbers are: principal quantum number (n), orbital, azimuthal, subsidiary or angular momentum quantum number (l), magnetic quantum number (ml), and spin quantum number (ms).

In the arrangement above, the electrons are arranged in order of increasing energy. Each arrangement of quantum numbers corresponds to a particular energy state of the electron.

Which of the following forms a molecular solid? Which of the following forms a molecular solid? C10H22 CaO gold C, graphite
Oxana [17]

Answer:

C10H22

Explanation:

Graphite is known as an allotrope of carbon. Its characteristics include being black and slippery and as used as lubricants.

Gold (Au) is an element on the periodic table with atomic number 79 and a mass number 197 which exists as a metal due to its hydrogen bonds.

C10H22 which is also known as decane belongs to the Alkane family.The General forces of attraction between the alkane family are weak but in the case of decade there is Van der waal force which makes Decane C10H22 a Molecular Solid.
