Answer:
The temperature is 42.5 °C
Explanation:
We apply the Law of Ideal Gases to solve this:
P . V = n . R . T
First, we convert the bar into atm, so we make a rule of three.
1.013 bar is 1 atm
1.3 bar is (1.3 . 1) /1.013 = 1.28 atm
1.28atm . 15L = n . 0.082 . T
We must convert the mass to moles ( mass / molar mass)
20 g / 30 g / mol = 0.666 moles
1.28atm . 15L = 0.666 mol . 0.082 . T
(1.28 atm . 15L) / (0.666 mol . 0.082) = T
315.5 K = T
As this is absolute temperature we must convert to °C
315.5 K - 273= 42.5 °C
Hey there!
Great question;)
Answer:it is neutrally charged because it has the same number of protons(positively charged iona) and electrons(negatively charged ions)
I hope this helps:)
Answer:
O 9 carbon atoms, only
Explanation:
Prefix: non- simply means 9.
Suffix: -ene means double bond, -yne means triple bond, and -ane means single bonded carbons.
The correct answer is<span> C) Water takes long to heat and cool down than other liquids.
It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>
