Answer:

Gjvb

Explanation:

Using the combined gas law equation as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (kPa)

P2 = final pressure (kPa)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question;

T1 = 300K

T2 = -73 + 273 = 200K

P1 = 303kPa

P2 = 202kPa

V1 = 2L

V2 = ?

Using the above formula:

303 × 2/300 = 202 × V2/200

606/300 = 202V2/200

Cross multiply;

606 × 200 = 300 × 202V2

121200 = 60600V2

V2 = 121200/60600

V2 = 2L

The new volume is 2L

morpeh [17]
<span>Answer:
             Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as <u>Chiral Molecules</u>.

Explanation:
                   Chiral molecules have stereogenic centers. When plane polarized light is fall on these compounds they rotate the light either in clockwise or anti clockwise direction. The mirror images of chiral moleculecules are non-superimposable.  Below few examples for molecules containing chiral centers are given.</span>

If an atom has 8 protons. How many electrons does it have? What is the atoms charge?
Juli2301 [7.4K]
The amount if protons is the same as the amount of electrons, so it would be 8. The charge is -2. Look at oxygen in the periodic table.
