Moles=concentration x volume. 1.5/1000 multiply 0.450 = 6.75x10^-4
To find the mass of fecl3, we have the formula, mass=moles x molar mass. 6.75x10^-4 x (55.8+35.5 x 3). = 0.1096g
Not sure tho if i did it right
Answer:
See explanation
Explanation:
The compound is acetylacetone. This compound is immiscible with water because it is completely nonpolar.
However the introduction of ammonia, leads to the ionization of the specie. In the presence of a base(such as NH3), the molecule acetylacetone is deprotonated and its corresponding anion is formed. This anion can now interact with water and become miscible with it.
Answer:
D
Explanation:
Elements in the same group (vertical columns) have the same number of valence electrons. These elements behave similarly because they will either give up or take the same number of electrons to fill their valence shell. Since potassium has 1 valence electron, it will most likely give up one electron. Out of all of the answer options, the only element that is in the same group as potassium is francium.
