Answer:
The number of moles of gas in the sample = 0.916 moles
Explanation:
Step 1: Data given
Volume of the container = 8.5 L
Temperature = 55 °C = 328 K
Pressure = 2.9 atm
Step 2: Calculate the number of moles of gas in the sample.
p*V = n*R*T
⇒with p = the pressure = 2.9 atm
⇒with V = the volume of the container = 8.5L
⇒with n = the number of moles of gas = ?
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 328 K
n = (p*V)/(R*T)
n = (2.9*8.5)/(0.08206*328)
n = 24.65 / 26.91568
n = 0.916 moles
The number of moles of gas in the sample = 0.916 moles
Answer:
Silicon
Explanation:
One of the most similar elements to carbon on periodic table is silicon. Several compounds formed between carbon or silicon and other elements are identical.
Carbon is an element found in life forms as a building block while silicon is a building block of machine components such as semiconductors
Silicon is an element that can sustain bonds, similar to carbon bonds and it is situated directly under carbon on the periodic table
<span>In polar coordinates, the origin is called the pole. Polar coordinate system is actually a two dimensional coordinate system. In this type of system the reference point is known by the name of pole. I hope that this is the answer that you were looking for and the answer has come to your desired help.</span>
Answer: -
Bond dissociation energy is the energy required to dissociate two atoms with covalent bonds.
This energy must be supplied during the course of a reaction.
Interesting to note that not all the bonds need to be broken during a chemical reaction, only the ones involved in the reaction.
