Answer:
The independent variable in this experiment is what he feeds the chickens (rice or corn).
Explanation:
The independent variable is the variable the experimenter manipulates or changes.
Answer:
Boils first >Pentane at high altitude> Hexane at high altitude>hexane at sea level> hexanol at sea level> boils last.
Explanation:
Step 1: To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.
(Hexanol> Hexane> Pentane)
Step 2: Identify which situation is most conducive to boiling
To boil, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.
In which situation would you expect the liquid to boil first, assuming equal heating.
(weak intermolecular attraction and low atmospheric pressure)
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
