Answer:

3.6 atm.

Explanation:

Given:

V1 = 375 ml

P1 = 1.2 atm

V2 = 125 ml

Using Boyle's law,

P1 × V1 = P2 × V2

P2 = (1.2 × 375)/125

= 3.6 atm.

Answer:

It exerts a pressure of 3.6 atm

Explanation:

This is a gas law problem. We are looking at volume and pressure with temperature being kept constant, thus, the gas law to use is Boyle’s law. It states that at a given constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.

Mathematically; P1V1 = P2V2

Let’s identify the parameters according to the question.

P1 = 1.2 atm

V1 = 375mL

P2 = ?

v2 = 125mL

We arrange the equation to make room for P2 and this can be written as:

P2 = P1V1/V2

P2 = (1.2 * 375)/125

P2 = 3.6 atm

What do you notice when you get into a car that has been sitting in the sun for a while?
Alona [7]

Answer:

I notice that it's extremely hot after it has been sitting in thr sun for a while. The sun's rays have been directly shining on the car because the car was in the sun's Ray's directly. If the car's windows were to be left open, it would be less hot but still be hot if the rays of the sun were directly on the car.

The Group 8A(18) elements The Group 8A(18) elements are unreactive and are rarely found in combination with other elements. are
valentina_108 [34]

Answer: Option (a) is the correct answer.

Explanation:

It is known that elements which have completely filled octet when they are present in neutral state then they do not need to gain or lose an electron. Hence, the element becomes unreactive in nature.

For example, neon is a noble gas whose atomic number is 10 and its electronic distribution is 2, 8. As they have completely filled orbitals so they do not react with other elements.

As a result, they are rarely found in combination with other elements.

Thus, we can conclude that the Group 8A(18) elements are unreactive and are rarely found in combination with other elements.

Free radical chlorination of ethane can produce higher halogenation products (dichlorinated, trichlorinated, etc...) in addition
Kryger [21]

Answer:Use an excess of ethane

Explanation:

The halogenation of alkanes is a substitution reaction. All the hydrogen atoms in the alkanes could be potentially substituted. How ever the reaction can be controlled by using an excess of either the alkane or the halogen. If the aim (as it is in this question) is to minimize the yield of halogenated alkanes, an excess of the alkane (in this case, ethane) is used.
