Answer:
i would assume that it would be (a)
Explanation:
The Sun generates its energy by nuclear fusion
NUCLEAR FISSION is when the heavy atom is split
fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments
mass gets lost is nuclear fusion
so (a) is the most accurate
The value of Kc for this reaction is 4.27.
Balanced chemical reaction: Fe3+(aq) + 3OH–(aq) ⇌ Fe(OH)3
c(Fe3+) = 0.555 M; concentration of iron ions
c(OH-) = 0.750 M; concentration of hydroxide ions
m(Fe(OH)3) = 3.6 g; mass of iron(III) hydroxide
The equilibrium constant (Kc) is a ratio of the concentration of the products to the concentration of the reactants (in this reaction iron and hydroxide ions). Concentration of the product is 1, because it is in the solid state.
Kc = 1 / c(Fe3+) x c(OH-)³
Kc = 1 / (0.555 M x (0.750 M)³
Kc = 4.27; equilibrium constant for this reaction.

Answer:
the atom is unreactive due to the completely filled electron configuration so the atom with the seven valence cannot involved in it
Answer:
Density = 4.191 gm/L
Explanation:
Given:
Molar mass = 93.89 g/mol
Volume(Missing) = 22.4 L (Approx)
Find:
Density at STP
Computation:
Density = Mass/Volume
Density = 93.89 / 22.4
Density = 4.191 gm/L
F and O
because they are more reactive than Cl
