At STP, pure ethanol has density 0.789g/mL. 25 mL will have mass 25 (mL) * 0.789 (g/mL)=19.725 g. Round this to 19.7g for three significant figures.
(not fully sure if this is correct)
A scientific theory is a well tested explanation of a natural phenomenon.
Answer:
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
I can give you a example like f<span>or example, in the reaction of calcium and chlorine, the compound is called calcium chloride. It is composed of </span><span>Ca 2+ cations</span><span> and Cl </span>- anions<span>; those ions are stable since they have filled valence shells. Its ionic formula is written as CaCl </span>2<span>, the neutral combination of these ions</span>
