Electric
field strength = Electric force/charge
E = F/q
E = (1.8×10^-1) / (6.4×10^-7)
E = 2.81×10^5 NC^-1
Hope it helped!
Answer:
H3PO4 + 5HCl → PCl5 + 4H2O
Explanation:
Answer:

Explanation:
First step
To calculate by how much the pressure has been increased we must find a relation between Vrms and the pressure p

Where M is molar mass,R is gas constant and T is temperature
As R and M is constant so we obtain
Vrams∝√T
Second step
From Ideal gas law we know that

we will find that
p∝T
So from first and second step, we can obtain that
Vrms∝√p
And a relation between both of them could be given by:
![\frac{V_{rms1} }{V_{rms2}}=\frac{\sqrt{p_{1} } }{\sqrt{p_{2}} }\\ p_{2}=[\frac{(V_{rms1})^{2} }{(V_{rms2})^{2} }]p_{1}\\ p_{2}=\frac{(276m/s)^{2} }{(176m/s)^{2} } (2atm)\\p_{2}=4.9188atm](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7Brms1%7D%20%7D%7BV_%7Brms2%7D%7D%3D%5Cfrac%7B%5Csqrt%7Bp_%7B1%7D%20%7D%20%7D%7B%5Csqrt%7Bp_%7B2%7D%7D%20%7D%5C%5C%20%20p_%7B2%7D%3D%5B%5Cfrac%7B%28V_%7Brms1%7D%29%5E%7B2%7D%20%20%7D%7B%28V_%7Brms2%7D%29%5E%7B2%7D%20%7D%5Dp_%7B1%7D%5C%5C%20%20p_%7B2%7D%3D%5Cfrac%7B%28276m%2Fs%29%5E%7B2%7D%20%7D%7B%28176m%2Fs%29%5E%7B2%7D%20%7D%20%282atm%29%5C%5Cp_%7B2%7D%3D4.9188atm)
The pressure is increased to 4.1988 atm, so the amount will be given by:

Answer: Water Vapor
Explanation:
Consequently, when water vapor is mixed with air, the density of the mixture will be less than that of dry air.
