Answer : The characteristic properties of a substance always remains the same irrespective of the sample being observed is large or small.
Few examples of characteristic properties of any substances includes freezing or melting point, boiling or condensing point, density, viscosity and solubility. They are specific for specific substances and which makes them easily recognizable.
Whereas chemical properties are specific for one substance which chemically transformed into another substances.
Answer:
16.4 L
Explanation:
we can use the combined gas law equation that gives the relationship among volume, temperature and pressure conditions of gases.
P1V1/T1 = P2V2/T2
STP conditions are standard temperature and pressure conditions
P1 is standard pressure = 1 atm , T1 is standard temperature = 273 K
and V1 is the volume
P2 is pressure, T2 is temperature and V2 is volume at the second instance
temperature is in kelvin scale,
512 ° + 273 = 785 K
substituting the values in the equation
1 atm x 10.0 L / 273 K = 1.75 atm x V / 785 K
V = 16.4 L
new volume is 16.4 L

B) one Neutron
C) six Electrons
D) These masses are too tiny to measure
Answer:
C
Explanation:
Answer:
six electrons
Explanation:
Electrons have almost virtually no mass and much less than a proton and neutron.
(a neutron and electron have about 1 amu while electrons have 0.000548 amu)
