Indefinite shape and definite volume I’m pretty sure I could be wrong tho
Answer:
theory
If it has been tested enough, then it can be considered a scientific theory.
Answer : The minimum mass of ethylene glycol is, 12000.2 grams.
Explanation : Given,
Molal-freezing-point-depression constant 
for water = 
Mass of water (solvent) = 14.5 kg
Molar mass of ethylene glycol = 62.07 g/mole
Formula used :
where,
= change in freezing point
= freezing point of solution = 
Conversion used :
= freezing point of water = 
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water =
m = molality
Now put all the given values in this formula, we get
Therefore, the minimum mass of ethylene glycol is, 12000.2 grams.

A) The half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases
Explanation:
The rate at which elements decays radioactively is directly proportional to the number of atoms present in it. This is a simple first-order kinetics.
The half-life of a radioactive element is the time taken for half of the radioactive nuclei to disintegrates.
The shorter the half life, the larger the decay constant and the faster the decay process. If a radioactive decay is fast, the mass of the reactants will decrease significantly with time thereby producing more of the daughter isotopes.
The reactant in a radioactive decay are the parent isotopes. The products are the daughter isotopes.
