Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.
Answer:
this is for the first image with the marshmallows in campfire-There are two main processes that heat a marshmallow: absorption of campfire radiation photons and contact with very hot air rising off the fire convection. If we place the marshmallow directly above the fire, we get both.
