Which change to the experimental design would improve the reliability of the engineers' measurements? ОА.
using a liquid other than water to determine porosity
ОВ.
using flasks instead of beakers
OC
testing single samples from more than three locations
OD
testing more samples from each location

c

Explanation:

sorry if im wrong my apolgies but i think c cus thats the only one that says equal amounts of something

like to test a drop of each so its balanced

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
