Answer:
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
The given balanced equilibrium reaction is,
At eqm. conc. 1.85 M 9.26M 0.254M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is
I think it'd because of (4), the reactivity of gold atoms, or rather, it's unreactivity. Gold, unlike most metals, doesn't form an oxide layer when exposed to air (Which is why it's so valued in jewellery, the metal will never tarnish, only stay gold forever). This makes it weaker, and so it can be formed in to thinner sheets.
However, (3), the nature of bonds between gold atoms also allows for the metal to be flattened, as metallic bonds aren't amazingly strong, and allow for metals to bend. This is what makes pure metals so weak, and why we use alloys.
Answer:
true
Explanation:
i hope it's true, if not, then it's false, if anyone else answered but got it from the link, let me know to report it or you report it
C.
Anthracite has the highest carbon compact and fewest impurities.
Also, the highest calorific of all types of coal except for graphite.
