No, because they have different volumes.
Yes, because the number of moles is not dependent on the mass or the volume.
Yes, because the number of moles is only dependent on the mass per unit volume.
Answer: Yes, it is possible for each samples to contain 1 mole of a substance because the number of moles are not dependent on the mass or the volume.
Explanation:
The formula for the number of moles is given by:
As, the masses of 2 samples are different, so the number of moles will be dependent only on the molar masses of the samples.
Volume has no effect on the number of moles.
Thelimitations of forensic drug chemistry is (1) they cannot create drugs out ofwht they learned in chemistry although they can create one, (2) theire line of expertiseis limited to the illegal drugs and crime committed acts.
They know how to identify the drugs found at crime scenes.
c. colloids
b. suspensions
d. none of the above
Answer: B. Metallic (happy to help)
Explanation:
A calorimeter contains 500 g of water at 25°C.....
the temperature of the water inside the calorimeter is 39.4°C.....
The specific heat of water is 4.18 J/g-°C.
energy needed to heat the water = specific heat * mass * temp difference
= 4.18 J/g-°C * 500 g * (39.4°C - 25°C)
= 4.18*500*14.4
= 30096J
or approx. 30kJ
Energy=specific heat of water x mass of water x water's temperatures
=4.18x500x(39.4-25)
=30096J
The substance in the air that makes the surface of limestone change is sulfur dioxide (SO2).
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It can form in a variety of ways, but most commonly it is formed from the accumulation of the remains of marine organisms such as coral, shells, and other calcium-rich materials.
Limestone is a common building material and is used in construction, as a flux in the production of iron and steel, and in agriculture as a soil conditioner. It is also used in the chemical industry to produce lime, carbon dioxide, and other chemicals. Limestone can be found in many parts of the world and is usually formed in shallow, warm marine environments.
