Well....radiation it a movement (Transfer ) of heat through electromagnetic waves( Example .....Sun Rays)
So a example would be getting sun burned on a hot day by the suns rays
C. Of the products is equal to the reactants.
Good luck out there! :)
Answer:C - 3.50g
Explanation:
To solve this problem, nitrogen is a gas and it's always two atoms of it in every reaction.
Using the formula
n = m/ Mm
n - number of mole
m - number of mass
Mm - number of molar mass
n = 0.125 mole
The molar mass of N2 = 14.0067 * 2 = 28.0134g/mol
(N - 14.0067 )
n = mass / molar mass
0.125 mol = mass / 28.0134g/mol
Mass = 0.125 * 28.0134
= 3.501675
= 3.50g
THE chemical formula of iron is Fe
Answer:
25 minutes
Explanation:
V = Volume = 
= Radon concentration under steady state = 1.5 Bq/L
k = Radon decay rate = 
= Venting rate = 
= Final concentration of radon = 0.15 Bq/L
Theoretical detention time is given by

We have the relation

The time taken to reach the acceptable level of concentration is 25 minutes.
