How does the average temperature change as the latitude decreases from the poles to the equator
igor_vitrenko [27]

As the earth is in the form of a sphere, the angle of incidence of the sun's rays at the earth's surface increases from the equator towards the poles and therefore the amount of heat received on a GIVEN AREA diminishes in the same direction. Temperature is therefore normally hottest near the equator and coolest near the poles.

What is the mass of 0.60 moles of Al?
nikitadnepr [17]

It helps to map out how you will navigate through your unit analysis problem before setting it up.  

You are given moles and need grams.  What can be used as a conversion factor from moles to grams?  Molar mass.  We are working with aluminum, so we will need the molar mass of aluminum.  My Periodic Table tells me the molar mass of aluminum is approximately 27 g/mol.  Now we are ready to set up the unit analysis.

0.60molAl(\frac{27gAl}{1molAl} )=16.2 gAl

Moles must go on the bottom so that they cancel.  Notice how our number of significant figures is 2, so the answer must round to 16 g Al.

<h3>Answer:</h3>

16 grams

Explain, in detail, how you convert grams of one substance to grams of something else. Be specific and include each step.
VashaNatasha [74]
First you divide the given mass of A (the initial substance) by its molar mass to get its number of moles. Then, based on a balanced chemical reaction, you divide the number of moles by the coefficient of A, then multiply by the coefficient of the product B. Finally, multiply by the molar mass of the product B (if there is a given conversion or yield %, multiply it as well), and this gives the amount of grams of the product.
