Answer:
The solubility of X in water at 17°C is 0.110 g/mL.
Explanation:
The water of a rock pool lined with mineral crystals is a <em>saturated solution</em> of said mineral, this means the concentration of X in those 36 mL is the solubility of compound X in water at 17 °C.
- This means<u> it is possible to calculate said solubility</u>.
The dilution of the sample is not relevant, nor is that 500 mL volume. What's important is that 3.96 g of X form a saturated solution with 36.0 mL of water, so the solubility is:
- 3.96 g / 36.0 mL = 0.110 g/mL
Lets get this straight:-
Protons → Positive charge, found in nucleus, heavy
Now, the only one we see that seems to be correct is A) positive charge, heavy, found in the nucleus of an atom
43g id say. Due to conservation of mass that is the only one that makes even slight sense. If you had more air react then the nail would heavier
The products of the neutralization reaction between hydrochloric acid and magnesium hydroxide are Magnesium chloride and water.
Ionic bond:
A bond resulting from the attraction between oppositely charged ions; one atom gives another electrons.
Covalent Bond:
A bond resulting from the shaing of pairs of electrons between two atoms.
(+1) + (-1) = 0
