Answer:
refractors and reflectors
Explanation:
Answer:
2H2 + O2 -----> 2H2O
Not sure about the second question though.
The number of outer electrons determines the chemical properties of an element, which is a correct statement. Because the number of valence electrons determines the bonding.
Answer: True
Answer: The greatest concentration of C would be produced if the equilibrium constant of the reaction is equal to 
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the given chemical reaction:

The expression for
is written as:
![K_c=\frac{[C]}{[A][B]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BC%5D%7D%7B%5BA%5D%5BB%5D%7D)
Thus higher is the value of
, higher will be the concentration of C. Thus the greatest concentration of C would be produced if the equilibrium constant of the reaction is equal to
