The final temperature is 46.5°C.
<u>Explanation:</u>
As per the Charles law, the volume of a gas at constant pressure is directly proportional to the temperature which is measured in Kelvin.
So the equation for the Charles law is given as,
Now we have to find T2 as,
V1 = 736 ml = 0.736 L
T1 = 15 ° C
V2 = 2.28 L
Now plugin the values as,
T2 =
= 46.5°C
So as we see that as the volume increases, temperature also increased.
Answer:
Protons, Neutrons, and Electrons
Explanation:
About Subatomic particles: Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
I'm not so sure but I would say it could be an iconic bond!
Mass of methane takne = 1.5g
moles of methane used = masss / molar mass = 1.5 / 16 = 0.094 moles
mass of water = 1000 g
Initial temperature of water = 25 C
final temperature = 37 C
specific heat of water = 4.184 J /g C
1) Heat absorbed by water = q =m• C• ΔT = 1000 X 4.184 x (37-25) = 50208 Joules
2) Heat absorbed by calorimeter = Heat capacity X ΔT = 695 X (37-25) = 8340 J
3) Total heat of combustion = heat absorbed by water + calorimeter = 50208 + 8340 = 58548 Joules
This heat is released by 0.094 moles of methane
So heat released by one mole of methane =
- 622851.06 Joules = 622.85 kJ / mole
4) standard enthalpy of combustion = -882 kJ / mole
Error = (882-622.85) X 100 / 882 = 24.84 %
Answer:
Each principal energy level has one sublevel containing one orbital, an s orbital, that can contain a maximum of two electrons.
