The subscript 3 outside of the parentheses means to multiply everything in the parentheses by 3, so it becomes a matter of addition:
3*(CH3) * (1 carbon atom)/(CH3) = 3 carbon atoms in (CH3)3
CH has one carbon atom and one hydrogen atom, so:
1 carbon atom in CH
Add both of them together, and you get 4 carbon atoms in isobutane
Answer: A. 219K
Explanation:
Using the Combined Gas Law; P1 V1/T1 = P2V2/T2
Where P1 = 0.92 atm, P2 = 1.00 atm
V1 =4.0 L, V2 = 5.0 L
T1 = ?, T2 = 25 celcius = 298K
We therefore make T1 the subject of the formular;
T1 = P1 . V1 .T2 / P2. V2
= 0.92atm x 4.0L x 298K / 1.00 atm x 5.0 L
= 1096.64 / 5
= 219.328 approx 219K
Answer:
D
Explanation:
only one that suggests anything about the sun/solar activity.
2.50 moles (55.85gramsof Fe/ 1 mole) (6.02 x 10^23 atoms / 1) = 8.41 x 10^25 because there is only one Iron present in the compund.
Answer:
2.The higher the humidity, the more water vapor the air contains, and warm air can hold more moisture than cooler air.
