Answer:
Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).
The Correct choice is ~ C
They have the same number of electron shells~
Answer:
<u>The pressure inside becomes : 202.646 KPa</u>
Explanation:
Given ,
- <em>The temperature inside the cylinder is constant</em>
- <em>The number of moles of the gas inside the cylinder will also be constant because it's a closed one.</em>
<em>Now according Boyle's law , </em>
- <em>The pressure of a gas of fixed mass is inversely proportional to its volume at a constant temperature.</em>
Thus ,
- is the initial pressure
- is what we need to find
- - initial volume
- - final volume
∴
The pressure inside becomes : 202.646 KPa

Answer:
a) HCN - hybridization sp
b) C(CH₃)₄ - hybridization sp³
c) H₃O⁺ - hybridization sp³
d) - CH₃ - hybridization sp³
Explanation:
Hybridization occurs to allow an atom to make more covalent bonds than the original electronic distribution would allow or to allocate ligands in an energetically stable geometry.
Carbon can have thre hybridization states: sp³ , sp² and sp.
Oxygen usualluy has an sp³ hybridization.
In order to determine the hybridization, we need to consider the number of atoms attached to the central atom and the number of lone pairs.
The figure attached shows the species and the hybridization of their central atoms.
