Dependent is a variable who's outcome depends on another variable. independent is a variable who's outcome doesn't depend on another variable only the researchers experimenting.
hope this helps !
Answer:
V₁ = 228 mL
Explanation:
There is some info missing. I think this is the original question.
<em>A chemist must prepare 575 mL of 50.0 mM aqueous potassium permanganate (KMnO₄) working solution. He'll do this by pouring out some 0.126M aqueous potassium permanganate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the potassium permanganate stock solution that the chemist should pour out. Round your answer to 3 significant digits.</em>

We want to prepare 575 mL (V₂) of a 50.0 mM solution (C₂). To do so, we start, from a stock solution of concentration C₁ = 0.126 M. In order to find the volume V₁ that the chemist should pour out, we will use the dilution rule.
C₁ × V₁ = C₂ × V₂
0.126 M × V₁ = 50.0 mM × 575 mL
0.126 M × V₁ = 50.0 × 10⁻³ M × 575 mL
V₁ = 228 mL
the stability of the radioactive element
Explanation:
The stability of a radioactive element can influence the rate of nuclear decay reaction. Pressure, temperature and concentration only affects chemical changes. These factors would not have any effect on radioactive decay of an element.
- Every atomic nucleus have a specific neutron/proton ratio which ensures the stability of the nucleus.
- Any nucleus that deviates from the stability ratio will continue to split until it achieves stability.
- The more unstable a nucleus is, the faster it decays.
- This is the basis of radioactive decay of elements.
