Susan should follow PEMDAS,
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction,
So, the first step should be, to solve the equation in the parentheses.
I hope this helps!
Answer:
Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.
It is diffistion because it moves from an area of high concentration to low
I believe you would just put a 2 in front of NH3 and keep the other ones as 1
Yes... that is correct.
CH4 is methane so the coefficent in front of it would double the number of atoms of each element
