I think the answer is 26,88 liters
To balance the given equation, we apply elemental balance and count each elements per side. There are 2 nitrogens in the left side so there should be 2 moles of NO2. Since there are already 4 moles of O in the right side, there should be 2 moles of O2. Hence answer is a. Place the coefficient 2 in front of oxygen and nitrogen dioxide.
the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
B reactants then C is on the right side! If you take h2O and air (the reactants) then the product would be a snowflake. happy holidays!!
3.25 x 10¹⁴m
Explanation:
Given parameters:
Frequency of the radiation = 9.23 x 10⁻⁷hz
Unknown:
Wavelength of the radiation = ?
Solution:
The velocity of electromagnetic radiation is the same as that of the speed of light in vacuums.
Velocity = frequency x wavelength.
Velocity = 3 x 10⁸m/s
Since the unknown is wavelength, we factor it out:
Wavelength = 
Wavelength = 
= 3.25 x 10¹⁴m
