The three particles of any atom are
<u>electron</u>) the smallest particle and is held in shells around the nucleus of the atom
<u>proton</u>) is found in the nucleus and is much larger than an electron
<u>neutron</u>) the same mass as a proton and also found in the nucleus of the atom
Explanation:
Group 16 elements are oxygen family elements also called as chalcogens.This name is given for the their ore forming abilities. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium.
Group 16 have six electron in the outermost principal energy level or the valence shell and their general electronic configuration is ns2 and np4.
The volume of the sample of propane at STP is 0.62 mL.
<h3>What is volume?</h3>
Volume is the amount of space that a substance or object occupies.
To calculate the volume of gas at STP, we apply the formula below.
Formula:
- PV/T = P'V'/T'................. Equation 1
Where:
- P = Initial pressure of gas
- V = Initial volume of gas
- T = Initial temperature of gas
- P' = Standard pressure (SP)
- T' = Standard temperature (ST)
- V' = Volume of gas at STP.
Make V' The subject of the equation
- V' = PVT'/P'T.............. Equation 2
From the question,
Given:
- P = 320 torr
- V = 1.73 mL
- T = 30 °C = (30+273) K = 303 K
- P' = 760 torr
- T' = 273 K
Substitute these values into equation 2
- V' = (320×1.73×273)/(760×303)
- V' = 0.62 mL
Hence, the volume of the sample of propane at STP is 0.62 mL.

Answer: The balanced equation for given reaction is 
.
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example,
Number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Since atoms on both reactant and product side are equal. Therefore, this equation is balanced.
Thus, we can conclude that balanced equation for given reaction is .
