Label each Formula In the Chemical equation Below As either A reactant or a product

1 answer:

4 0

In chemical reactions, the reactants are consumed to create the products, and (assuming this is a normal chemical reaction) the reactants are located to the left of the arrow while the products are located to the right of the arrow. So in this case, Fe would be a reactant, S would be a reactant, and the FeS would be a product.

Hope this helps

How do you calculate the number of photons having a wavelength of 10.0 micrometers required to produce 1.0 kilojoules of energy

shtirl [24]

To calculate this,

We know that energy is 1 photon
E = hc/wavelenth
wavelength of 10.0 m

Solution:
h = 6.626 x 10^-34 Jsec
C = 2.9979 x 10^8 m/sec
E = 6.626 10^-34 * 2.9979 10^8 / 10 = 1.9864 10^-26J

Then, the number of photons is computed by:

n = 1000 / 1.9864 10^-26 = 5.04 10^28 photons
