Answer:
Draw circles to represent the electron shell of each atom overlapping the circles where the atoms are bonded. Add dots to represent the outer electrons of one type of atom (H). Add crosses to represent the outer electrons of the other type of atom (Cl). Make sure the electrons are always in pairs.
Answer:
SO < CO2 < C3H8
Explanation:
Entropy refers to the degree of disorderliness of a system. The standard molar entropy of a substance refers to the entropy of 1 mole of the substance vunder standard conditions.
The molar entropy depends on the number of microstates in the system which in turn depends on the number of atoms in the molecule.
C3H8 has 11 atoms and hence the highest number of microstates followed by CO2 having three atoms and least of all SO having only two atoms.
Answer:
A
Explanation:
1 lb = .453 kg...so...103 x .453 = 46.72 kg
you then multiply that by the force of gravity which is 9.8(m/s2)...so...
46.72 x 9.8 = 458 newtons(kg x m/s^2), which is the force.
pressure (in pascals) = Force(N) / Area (m2)
we need to convert 10cm2 to m2 which = .001m^2
458 / .001 = 458000 = 4.58 x 10^5 Pa
The troposphere has the most density because it has the most air pressure. As you get higher in the atmosphere, the air gets thinner, which is why people who climb high mountains get sick because the air is not thick enough for them to breathe.
