Answer:
Freezing and boiling point
Explanation:
A liquid form of any substance is an intermediate form between the solid form and the gaseous form.
Decreasing the temperature of liquid water according to the phase diagram of 
would freeze it and we would have a phase change from liquid to solid (ice) at the freezing point of water.
Similarly, heating water to its boiling point would evaporate water and we would have a phase change from liquid to gas (water vapor).
Therefore, liquid water exists between its freezing and boiling point.
Answer:
2Cu + O2 ----------------> 2CuO
Answer:
moles of ammonia produced = 0.28 moles
Explanation:
The reaction is
As per equation, one mole of nitrogen will react with three moles of hydrogen to give two moles of ammonia
So 0.140 moles of nitrogen will react with = 3 X 0.140 moles of Hydrogen
= 0.42 moles of hydrogen molecule.
this will give 2 X 0.140 moles of ammonia = 0.28 moles of ammonia
the moles of ammonia produced = 0.28 moles
Here the nitrogen is limiting reagent.
Benthos are "organisms inhabiting the seafloor" according to one source, so I would say the answer is C.
Answer:
58.44 g/mol
Explanation:
In this problem, make sure to remember that volume is measured in mL, L or any other units of volume. Remember that g represents grams, and grams is a measure of mass.
However, independent of what mass or what volume we take, molar mass is known to be an intensive property. That is, molar mass doesn't depend on any external conditions or any measurements.
Molar mass solely depends on the chemical structure of a compound and is a constant number at any given conditions.
In this problem, we are given sodium chloride, NaCl. In order to find its molar mass, we need to refer to the periodic table, find the atomic masses of Na and Cl and then add them up to have the molar mass of NaCl:
