Answer:
4 ions
1 M³⁺ ion and 3 NO₃⁻ ions ( Where M³⁺ stands for the group 13 cation).
Explanation:
Group 13 elements are Boron , Aluminium, Galium, Indium and Thalium. When they form ionic compounds they can lose their three valence electrons to form a tripositive (+3) ion. Nitrate ion is a negative ion with a single negative(-1) charge. When these two form a compound 3 univalent negative nitrate ions must combine with one tripositive group 13 element to form a neutral compound. So the total no of ions is 4.
Answer;
Fractional distillation
Explanation;
-Fractional distillation is one of the method that is used to separate mixtures. It is used for the separation of miscible liquids, for example water and alcohol.
-Fractional distillation is a distillation method that is used to separate liquids that dissolve in each other. It involves separating the components of a mixture by repeated distillations and condensations.
-The components in the mixture being separated by this method normally have different but close boiling points. For example a mixture of alcohol and water, they have different but close boiling points, thus during distillation alcohol condenses out as the first fraction followed by water.
A is 14
B is 9 is it right
A. (cold solutions hold on to their solutes better)
So if you put a holo ball of paper in the water it sinks and as it sinks it gets smaller cuse pressure so it cuseus things to shrink cuse of pressure
