Reasons why convection is responsible for the uneven heating of the air in the atmosphere

FULL ANSWER<span>As the sun heats Earth, land absorbs solar radiation more readily than water, which allows it to heat at a much faster rate. Heat radiates out from the planet's surface to warm the atmosphere through a process known as convention. Wind is created when the air above landmasses absorbs heat from the surface until it begins to expand and rise, drawing in heavier, cooler air from over the oceans to take its place. This process is reversed at night when air above the land cools more rapidly than air above the planet's oceans.Wind patterns and atmospheric currents are formed on a global scale because air near the planet's equator is heated more rapidly than the air found in polar regions. Global wind patterns include trade winds as well the jet stream, a river of air that forms a boundary between polar air masses and the warmer air found closer to the equator.Hope this helps xox :)</span>

If a 60-g object has a volume of 30 cm3, what is its density? 2 g/cm3 0.5 cm3/g 1800 g * cm3 none of the above
jasenka [17]

Answer : The density of an object is, 2g/cm^3

Solution : Given,

Mass of an object = 60 g

Volume of an object = 30cm^3

Formula used :

\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}

Now put all the given values in this formula, we get the density of an object.

\text{Density of an object}=\frac{60g}{30cm^3}=2g/cm^3

Therefore, the density of an object is, 2g/cm^3

According to the balanced equation shown below, 1.00 mole of oxalic acid, h2c2o4, reacts with _________ moles of permanganate io
zheka24 [161]
The balanced equation that shows the reaction between oxalic acid and permanganate ion in an acidic medium is: 2MnO4- + 5H2C2O4 + 6H+ -> 2Mn(2+) + 10CO2 + 8H2O. Thus, 1 mole of oxalic acid reacts with 0.4 mole of permanganate ion. This was obtained using stoichiometry:

1 mol H2C2O4 x (2 mol MnO4-/ 5 mol H2C2O4) = 0.4 mol MnO4- 

In this redox reaction, the permanganate is reduced to manganese(II) ion.

M1v1=m2v2 
m2=(m1v1)/v2 
Where m is the molarities and v is the volumes
<span>m2=(25.0*0.500)/53.5
m2=12.5/53.5
m2=0.2336
by rounding off:
m2=0.234 M
so the answer is C: 0.234 M</span>
