solution:
This iron oxide mineral commonly has a reddish color and consistently has red streaks. this streaks is hematite.
<span>C 13 has
Protons = 6
neutrons = 6
electrons = 13-6</span>
It has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.
In the given above, we have two densities which are 0.89 g/mL and 0.72 g/mL. We are also given that the liquids are immiscible. After the settlement of the liquids, they will form two layers.
The heavier substance, the one which has a higher density will be at the bottom and the lighter substance, the one which has a lower density will be at the top layer.
The solubility of PbBr₂(s) with the presence of 0.500 M of KBr is
2.64 x 10⁻⁵ M.
