Answer:
A. No; B. yes
Explanation:
A. Mass
The balloons contain different gases, which will have different densities.
Mass = volume × density
m = V × D
However, the volume is the same for all three balloons.
Thus m = kD
And the mass of the gas is directly proportional to the density.
Since the density varies, the mass varies.
B. Number of molecules
This is Avogadro's Hypothesis:
At the same conditions of temperature, equal volumes of gases contain the same number of molecules.
Answer:
The list and discussions are stated below:
Explanation:
Good Laboratory Practice (GLP) is extremely important.
1. Organization
With GLP we can guarantee an organized work environment, which is essencial in a laboratory.
2. Safety
GLP promotes laboratory safety for personell, avoiding unecessary risks and preventing accidents.
3. Quality control
GLP ensures that experiments made and products developed in a laboratory have the demanded quality.
4. Reliability of results
GLP promotes quality of results reporting, wich directly influences the reliability of results.
