Answer: Antarctica or anywhere
Explanation:
I hope this helps im not sure if I’m correct but I’m sure u can find them anywhere cold
Answer:
They have different amounts of neutrons.
They have different mass numbers.
Explanation:
Carbon-12 and carbon-13 are two isotopes of the element carbon. The difference between carbon-12 and carbon-13 is the number of neutrons in each atom. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-13 contain 7 neutrons. And because the mass number is the sum of protons and neutrons in the nucleus then will be different too. Atoms of carbon-12 have the mass number equal to 12 a.m.u. while atoms of carbon-13 have the mass number equal to 13 a.m.u. .
a.m.u. - atomic mass units
Call what you have to find is x
nHCl/V=12M
nHCl=2.0,25=0,5
->x=0,5.12=6 (600 ml)
Answer:
Explanation:
The question is asking, "At what temperature does the vapour pressure of water equal 3.4 atm?"
To answer this question, we can use the Clausius-Clapeyron equation:
Data:
p₁ = 1 atm; T₁ = 373.15C
p₂ = 3.4atm; T₂ = ?
R = 8.314 J·K⁻¹mol⁻¹
(The enthalpy of vaporization changes with temperature. Your value may differ from the one I chose.)
