ilter?
2 answers:
Answer: Hana collects the ocean water that passes through the filter.
Explanation;
When the Hana fills allows the sandy ocean mixture through a filter she will observe that, the sand particles present in the mixture getting collected on the filter and the water seeping down through the pores of the filter. This process followed by Hana is known as filtration process (as shown in figure attached).
In the end, Hana will be able collect the ocean water without sand present in it.

The above two reactions xcan also be written in form of single chemcial equation:
1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.
2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.
3. On mixing, KSCN with we will get blood red color solution of

Answer:
+2
Explanation:
If a compound existed, we would identify the oxidation state of sulfur using the following logic:
- oxygen is more electronegative than sulfur, so it's more electron-withdrawing and it should have a negative oxidation state producing a positive oxidation state for sulfur;
- oxygen typically has an oxidation state of -2;
- we may then apply the fact that SO is expected to be a molecule with a net charge of 0;
- if the net charge is 0 and the oxidation state of oxygen is -2, we may set the oxidation state of S to x;
- write the equation for the net charge of 0 by adding all individual charges of the two atoms:
;
- hence, x = 2.
That said, in this hypothetical compound S would have an oxidation state of +2.
