Answer:
F2, Br2, I2
Explanation:
The halogen diatomic molecules have a general formula X2. Based on periodic properties, the halogens all have similar chemical behavior. This implies that, F2, Cl2, Br2 and I2 all have similar chemical properties.
All these other X2 halogen molecules are likely to react with St, just as Cl2 does.
Answer:
false
Explanation:
it is false because it soulds right and i just did the quiz!!
Answer:
121.37 moles.
Explanation:
Always one mole of any molecule contains Avogadro number of molecules.
So one mole of methane contains 6.023*10^23 molecules.
Now we need number of moles of methane in 7.31*10^25 molecules.
This is just cross multiplication stuff.
6.023*10^23 molecules —————- 1 mole
7.31*10^25 molecules ——————- ?
= (7.31*10^25) / (6.023*10^23)
= 121.37 moles.
Answer:
Kc = 0.0122
Explanation:
For a given equilibrium reaction, the equilibrium constant is calculated by taking the ratio between the equilibrium concentrations of the products and the equilibrium concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients.
