Which is the correct Lewis dot structure of C2H2

Chemistry
1 answer:
denpristay [2]3 years ago
3 0

The correct answer is A

The octet rule state that all main group elements form bonds such that they achieve a noble gas configuration with eight valence electrons. In this case carbon has 4 electrons in its outermost shell  and requires 4 more electrons to achieve an octet. Hydrogen is an exception to the octet rule and it only requires two electrons to achieve an octet. All the other options have C and H  forming bonds that do not lead to a noble gas configuration.

At a pressure of 650 kpa 2.2L of hydrogen is used to fill a balloon to a final pressure of 115 kpa. What's the balloons volume?
Alborosie

Answer:

V₂ = 12.43 L

Explanation:

Given data:

Initial pressure = 650 KPa

Initial volume = 2.2 L

Final pressure = 115 KPa

Final volume = ?

Solution:

The given problem will be solved through the Boyles law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

650 KPa ×2.2 L = 115 KPa × V₂

V₂ = 1430 KPa. L/ 115 KPa

V₂ = 12.43 L

How do I convert units the easiest
damaskus [11]
To convert among units in the metric system, identify the unitthat you have, the unit that you want to convert to, and then count the number of units between them. If you are going from a larger unit to a smaller unit, you multiply by 10 successively
