Answer:
Im pretty sure that 5N to the Right is correct answer
Answer:

Explanation:

Assume 1 kg water.
1. Moles of P.HCl
Then we have 4.666 mol of P.HCl
2. Mass of P.HCl
n = 4.666 mol × 272.77 g/mol = 1271.1 g
3. Total mass of solution
m = 1000 g + 1271.1 g = 2271.1 g solution
4. Volume of solution

5. Molar concentration


Answer:
The correct answer is sedimentary rock.
Explanation:
The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.
Answer:
2.3 M
Explanation:
First we calculate the final volume of the solution:
- Final Volume = 200 mL + 700 mL
With the final volume we can use a <em>dilution factor</em> to c<u>alculate the concentration of the diluted solution</u>:
- Original Concentration * Initial Volume / Final Volume = Final Concentration
- 3 M * 700 mL / 900 mL = 2.3 M
Fe is the pure element (Iron) while Fe2+ is an isotope of Fe.
