<span>Energy is calculated by molecule dividing energy by mole by Avogadro's number (6.022*10^23)
941kJ=9.41*10^5 J
so energy by molecule
E= 9.41*10^5/6.022*10^23=1.563*10^-18 J
Wavelength (w) given by E=hc/w
where, E = energy
h = planks constant (6.6262 x 10-34 J·s)
c = speed of light (3 x 10^8 m/s )
So,
w= hc/E
= (6.6262*10^-34)*(3*10^8) /1.563*10^-18
= 127.2 Nm
Longest wavelength of radiation =127.2 Nm</span>
Answer:
true is correct answer answer
Yes, this equation is balanced.
You can check it using the law of conservation of mass, i.e., the total mass of the products formed must be equal to the total mass of the reactants.
Answer:
1.53 m/s
Explanation:
Velocity is given in meters per second, so if it takes the swimmer 72 second to swim 110 meters:
m/s = 110 meters / 72 seconds = 1.527 or 1.53 m/s
