Answer:
The mass of the lead
Explanation:
The 5g mass of the lead is an extensive property.
An extensive property is a physical property of matter which depends on the amount of matter that is present there in. Mass, volume e.t.c are all extensive properties. The more the quantity of the lead, the more its mass and the volume it occupies.
Melting point, boiling point, density are all intensive propeties. These properties do not rely on the amount of matter present. Any amount of lead will have the same density.
Answer:
The reaction will be spontaneous.
Explanation:
- The change in free energy (ΔG) is the difference between the heat released during a process and the heat released for the same process occurring in a reversible manner.
- The sign of ΔG gives an indication for the spontaneity of the reaction:
If ΔG is negative, the reaction is spontaneous.
If ΔG = zero, the reaction is at equilibrium.
If ΔG is positive, the reaction is non-spontaneous.
I think the answer is OPC
Answer:
Explanation:
The expression for density is:
M is molar mass of Chromium = 51.9961 g/mol
For body-centered cubic unit cell , Z= 2
is the density
Radius = 125 pm =
Also, for BCC,
Thus,
“A class C fire is an energized electrical fire. ... “Class C” is a term that distinguishes a fire from class A and class B fires. Class A is a category for fires consuming a source like fire or wood that can be extinguished with water, and class B fires are fueled by flammable liquids like gasoline.”
