The focus of the bandwagon advertising style is to try to persuade someone to do something based on the fact that "everyone's doing it."
For example, today's girls all have eyebrows "on fleek" because everybody's doing it. It's a banal example, but it paints the picture clearly.
Hello! Your answer is C, one atom of iron and three atoms of chlorine.
In this case, there is some ambiguity with "Cl". It could be C + I, or Cl. (One being carbon + iodine and the other Chlorine). However, we can see that the only choice that mentions iodine states two atoms, which is incorrect, as if it was iodine, the 3 indicates that there would be three atoms.
Therefore, Cl must be chlorine. If you look at choice C, there are three atoms of chlorine, as indicated by the 3 at the end of the Cl. There is also one molecule of Fe, as there is no number at the end of it so there has to be only one.
B is not correct, as carbon would be only "C". A is not correct as a molecule is a collection of atoms bonded together, therefore, this compound could be named a molecule, but there are not multiple molecules inside this compound.
Hope this helps!
The answer is fused glass.
The general structure for a Ka expression is:
In this expression,
-----> Ka = equilibrium constant
-----> [A⁻] = base
-----> [HA] = acid
The products are in the numerator and the reactants are in the denominator. In this case, H₃PO₄ serves as an acid and H₂PO₄⁻ serves as a base.
As such, the equilibrium expression is:
