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:
We can seperate a mixture by various methods
Explanation:
Distillation, Evaporation, filtration and chromatography
The total width of the crystal is determined by multiplying the spacing which is equal to 18.1 x 10^-9 m by the total number of molecules.
Width = (18.1 x 10^-9 m)(108)
The simplification of the operation above will give us an answer of 1.958 x 10^-6 m. We can convert this to millimeters as below,
(1.958 x 10^-6 m)(1000 mm/1 m)
= 1.9548 x 10^-3 mm
<em>Answer: 1.9548 x 10^-3 mm</em>
Answer:
Explanation: first use a balance to get the masses of these items. Once the masses of these items are measured, we can then calculate the moles.
The mole is = mass/molarmass
