C. Convection currents in the air

Explanation:

Near the shore, winds tends to blow out towards the water at night and this is driven by convection currents in the air.

Convection occurs in fluids. Since we are dealing with wind, therefore, it is convection in air.

  • At night, the air on land is cold and under high pressure.
  • The shore area is able lose and gain heat very fast.
  • At night, since the shore is cold, the air around is cold too.
  • The ocean has high heat capacity and does not lose or gain heat easily.
  • At night, it still retains come of its heat.
  • This causes nearby winds to warm up, becomes less dense and rises.
  • The wind here is moves towards the cold land
  • The breeze on land moves outwards towards the ocean.
  • This will then set up convection currents.

How does the force of gravity on Jupiter compare to the force of gravity on Earth?
iogann1982 [59]

Jupiter has greater gravitational pull than earth, about 2.4 time greater than that of earth. This means that a person weighing 100 pound on earth will weigh 240 pounds on Jupiter.

Jupiter is the largest planet in the solar system. It is so large that all other planets would comfortably fit inside it. It is over 1000 times bigger than the earth.

Jupiter is the fifth planet from the sun and rotates faster than any other  planet. A day in Jupiter is about 10 hours long.

What is the bond order of li2−? express the bond order numerically?
jeka94
Atomic Number of Lithium is 3, so it has 3 electrons in its neutral state. Also, Li₂ will have 6 electrons. But the chemical formula we are given has a negative charge on it (i.e Li₂⁻) so there is an additional electron (RED) present on this compound. So, the total number of electrons are 7. The MOT diagram for this compound is shown below. According to diagram we are having 4 electrons in Bonding Molecular Orbitals (BMO) and 3 electrons in Anti-Bonding Molecular Orbitals (ABMO). Bond Order is calculated as,

              Bond Order  =  (# of e⁻s in BMO - # of e⁻s in ABMO) ÷ 2

              Bond Order  =  (4 - 3) ÷ 2

              Bond Order  =  1 ÷ 2
Or,
              Bond Order  =  1/2
Or,
              Bond Order  =  0.5

To three significant digit,what is the mass percentage of iron in the compound Fe2O3​
svlad2 [7]

69.9%

Explanation:

To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.

 Mass percentage  = \frac{molar mass of Fe}{Molar mass of Fe_{2}O_{3}  }  x 100

Molar mass of Fe = 55.85g/mol

Molar mass of O = 16g/mol

Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7‬g/mol

Mass percentage  = \frac{2(55.85)}{159.7}  x  100   = 69.94% = 69.9%
