The equilibrium constant, represented as a variable K, is the ratio of the concentration of the products to the reactants which are raised respectively to their stoichiometric coefficients. Note that only substances in the aqueous phases are accounted. From the reaction given, K is equal to
<em>K = [Sn²⁺]³/[Fe³⁺]²</em>
Once you know the equilibrium concentration of Sn²⁺ and Fe³⁺ in molarity, just substitute them into the equation to solve for K.
Answer:
n = 3 for similar blue light
Explanation:
The principle applied here is energy levels and energy changes. There are different energy levels depending on the value of the integer as explained by Max planck - a german physicist in 1900, Max planck claimed that electrons in an atom were presumed to be oscillating with a frequency f, then there enrrgy will be given by the plancks equation ; E =hf, where h is the plancks constant.
In general energy of each level can be written as E =nhf
The Answer would be C. Without plants in the ecosystem, it could not feed. Plants are mainly the only producers that feed 3rd level consumers which feed 2nd level consumers which feed 1st level consumers.
Answer:
a. 41 mg equals 0.041 grams.
b. 41 mg equals 0.0014462 ounces
c. 41 mg equals 9.039*10⁻⁵ pounds
Explanation:
You know that a slice of Swiss cheese contains 41 mg of sodium.
a. What is this mass in grams?
Knowing that 1 mg = 10⁻³ g, you can apply the following rule of three: if 1 mg equals 10⁻³ g or 0.001 grams, 41 mg will be equivalent to how much mass in g?

mass= 0.041 grams
<u><em>
41 mg equals 0.041 grams.</em></u>
b. What is this mass in ounces?
Knowing that 1 mg = 3.5274 * 10⁻⁵ ounces, you can apply the following rule of three: if 1 mg equals 3.5274 * 10⁻⁵ ounces, 41 mg will be equivalent to how much mass in ounces?

mass= 1.4462*10 ⁻³ ounces= 0.0014462 ounces
<u><em>41 mg equals 0.0014462 ounces</em></u>
c. What is this mass in pounds?
Knowing that 1 mg = 2.20462 * 10⁻⁶ pounds, you can apply the following rule of three: if 1 mg equals 2.20462 * 10⁻⁶ pounds, 41 mg will be equivalent to how much mass in pounds?

mass= 9.039*10⁻⁵ pounds
<u><em>41 mg equals 9.039*10⁻⁵ pounds</em></u>
