When answering this question, you must consider the reactivity series. Mg is much higher than Zn in the reactivity series, therefore it can displace the Zn from the solution - displacement reaction.
It seems odd that you'd react Magnesium nitrate with zinc nitrate. Maybe you meant magnesium with zinc nitrate or vice Versa. Because in your case each compound would remain as it is as both Mg and Zn are happy in a relatively stable compound.
As for magnesium nitrate and magnesium nitrate, you cannot achieve a reaction between two substances that are the same. The same applies for Mg and magnesium nitrate. No displacement happens.
Hope it helps!
The correct option is C, OIL AND VINEGAR
There are two types of mixture, homogeneous and heterogeneous mixtures.
Homogeneous mixture are uniform in composition and an example of this is milk.
Heterogeneous mixture refers to a mixture which is not uniform in composition, that is, smaller constituent parts is present in it and it can be easily separated using suitable methods.
Answer: SO2(Sulfur Dioxide) Molecular Geometry & Lewis Structure
Explanation: So2Molecular Geometry
We know that the shape which minimizes the repulsions of electronics pairs is adopted by the molecule to form the structure. The molecular shape of SO2 is same as the molecular geometry of Carbon Dioxide (CO2). We will show the bonding of SO2 without making assumption below.
O =S =O
Answer:
Chemical formula for the black iron oxide sample is FeO
Explanation:
<u>Given:</u>
Mass ratio of black iron oxide sample, Fe/O = 3.491
<u>To determine:</u>
The chemical formula
<u>Calculation:</u>
The mass ratio is Fe:O = 3.491 : 1
Mass of Fe = 3.491 g
Mass of O = 1.000 g
Atomic mass of Fe =55.85 g/mol
Atomic mass of O = 16.00 g/mol
Therefore, the molar ratio of Fe:O = 1:1
Hence, chemical formula is FeO
