Jia observes that adding a solution of sodium hydroxide to a clear liquid turns the liquid pink. She makes a hypothesis about why the liquid changed color.
Which characteristic is least important for her hypothesis to have?
A)ability to be tested
B)based on the opinion of her classmates
C)ability to be proven incorrect
D)based on her current knowledge
Answer:
B)based on the opinion of her classmates
Explanation:
A hypothesis is a supposition or tentative explanation put forward based on minimal evidence. It sometimes sets the pace for further investigation.
Hypothesis is always based on empirical observation and not on popular opinion, hence the opinion of Jia's classmates is least important in Jia's formulation of a hypothesis.
When comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.
<h3>What is an electrolytic cell?</h3>
In an electrolytic cell, the reaction is non-spontaneous so it requires some input of energy for it to function while for a voltaic cell, the reaction is spontaneous.
Oxidation occurs at the anode and reduction occurs at the cathode.
Thus, when comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

Manganese is an element.
Manganese is the 25th element on the periodic table. As it is an element, it means it cannot be separated or broken down into anything simpler, even by chemical methods such a electrolysis.
In additional, compound is where 2 or more elements are chemically bonded together, which usually involves heat, while mixture is where 2 or more elements or Compounds mixed together in any proportions.
