Please type the question.
Explanation:
I can't answer it if you don't write the question
The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.
Explanation:
The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.
It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.
The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.
The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.
For example the structural formula for Methane (CH4)
Explanation:
The given data is as follows.
Q = 620 C, t = 0.510 hour
First, we will convert hours into seconds. Since, there are 3600 seconds present in 1 hour. Hence, number of seconds present in 0.510 hour are as follows.
= 1836 sec
Therefore, we will calculate the average current as follows.
I = 
= 
= 0.337 C/sec
It is known that,
1 C/sec = 1000 mA
So, 
= 337 mA
Thus, we can conclude that the average current in milliamperes is 337 mA.
