Phosphoric acid is a weak acid, while rubidium hydroxide is a strong acid.
H₃PO₄ + RbOH --> Rb₃PO₄ + H₂O
We get Rb₃PO₄ because PO₄ has a charge of 3-, that is PO₄³⁻. Rb has a charge of 1+. You give the subscript of one the charge of the other as this is an ionic compound. So you end up with Rb₃PO₄, a neutral compound.
Now let's balance the equation:
H₃PO₄ + 3RbOH --> Rb₃PO₄ + 3H₂O

Answer:
Homo means same
Hetero means different.
Homogeneous mixtures have one phase, it all looks the same, Fruit juice is homogeneous, solutions are homogeneous.
Heterogeneous mixtures have different phases, you can see the different parts, pepper is an example of a heterogeneous mixture.
- A homogeneous mixture - Think Kool Aid (Completely Dissolved)
- A heterogeneous mixture - Like pepper poured into a glass of milk.
In a homogeneous mixture the constituents are able to dissolve in each other due to their similar intermolecular forces, whereas in a heterogeneous mixture the constituents are not miscible- meaning they can't dissolve in each other.
To clarify: intermolecular forces describe the way that types of molecules will interact with each other. For instance, water (a polar molecule) and naphthalene (a non-polar molecule) are said to be "immiscible" because their intermolecular forces do not match. The saying goes: "like dissolves like". Meaning that molecules that have similar IFs will be mutually soluble (miscible, in other words).
- Homogenous means the same all over...every cubic millimeter is about the same as every other one. Like water or soda.
- Heterogenous means difference in places, like salsa, with slightly different chunks of stuff depending on where you dipped your chip.
I think the answer might be C. Planets. Not exactly sure though... Let me know if this was correct!! :-)
