<h3>Answer :</h3>
<h3>Specific Heat</h3>
<h3>Explanation :</h3>
<h3>The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kgoC). Water has a large specific heat of 4.19 kJ/kgoC compared to many other fluids and materials.</h3>

The laboratory aid that is used to transfer liquid from a wide-mouth container to a small-mouth container is the funnel. It is shaped like an inverted cone, with an extension of a small tube where the liquid passes. The filter paper is shaped into a cone and inserted to the funnel. The funnel allows you to transfer the liquid without spilling. In filtration, you separate the solid precipitate from the liquid filtrate. It depends on you which one of these you would keep. If you want to keep the filtrate, then the funnel is an efficient way to use if you don't want any of the filtrate to go to waste.
Answer:
the answer is C. 3. measure the mass of the liquid in both beakers

Answer:
15.9994 amu
Explanation:
By definition 1 mole of any substance is the mass that contains 1 Avogadro's Number of particle. (=> 6.02 x 10²³ particles/mole).
1 mole Oxy => 15.9994 amu => contains 6.02 x 10²³ particles Oxy /mole
1 mole Sulfur => 32.064 amu => contains 6.02 x 10²³ particles Sulfur /mole
1 mole H₂O => 18 amu => contains 6.02 x 10²³ molecules of water / mole.
