Because their is no motion in them their for they can not do anything but just sit their I hope I helped u if not I’m so so sorry
Answer:- 1467 K
Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.
Given: ![n=7.16*10^-^4moles](https://tex.z-dn.net/?f=n%3D7.16%2A10%5E-%5E4moles)
V = 75.0 mL = 0.0750 L
P = 116.8 kPa
We know that, 101.325 kPa = 1 atm
So, ![116.8kPa(\frac{1aym}{101.325kPa})](https://tex.z-dn.net/?f=116.8kPa%28%5Cfrac%7B1aym%7D%7B101.325kPa%7D%29)
= 1.15 atm
R is universal gas constant and it's value is
.
T = ?
Let's plug in the values in the equation and solve it for T.
![1.15(0.0750)=7.16*10^-^4*0.0821(T)](https://tex.z-dn.net/?f=1.15%280.0750%29%3D7.16%2A10%5E-%5E4%2A0.0821%28T%29)
0.08625 = 0.00005878(T)
![T=\frac{0.08625}{0.00005878}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B0.08625%7D%7B0.00005878%7D)
T = 1467 K
So, the temperature of the light bulb would be 1467 K.
The total number of electron pairs that are shared between the two carbon atoms in a molecule of ethyne is 3.
Answer:
(a).molar mass=(12×9)+(1×8)+(16×4)
=180.0g
(b).moles of Aspirin
moles=mass(g)÷molar mass
=360.4÷180.0
=2.002moles
(c). molecules of Aspirin
To get molecules just multiply moles of Aspirin by Avocado number.
=2.002×6.022×10^23
=1.206×10^24 molecules
(d) number of carbon atoms
=12×9
=108 carbon
