Answer: The number of energy levels increases as you move down a group as the number of electrons increases
Explanation: hope this works!!!
Answer:
C₄H₆
Explanation:
A hydrocarbon is a molecule that only contains atoms of Carbon and Hydrogen. As you remember, the molar mass of Carbon is 12g/mol and the molar mass of Hydrogen is 1g/mol.
To solve this question we can find the amount of Carbons necessary that doesn't exceed the 54g/mol. That is:
54g/mol / 12g/mol = 4.5
As the molecular formula must be given in whole numbers, the amount of Carbons is 4. This 4 carbons have a mass of:
12g/mol*4 = 48g/mol
And the hydrogens necessaries to suply the molecular mass are:
54 - 48 = 6 hydrogens
That means molecular formula is:
<h3>C₄H₆</h3>
Answer: use the cubic feet per hour formula (cfh)
Explanation: multiply room times height times the width times the length and that gives you the cfh and then you just divide the cfh by the volume of the room to get your answer
