The correct answer for the question that is being presented above is this one: "NH4Cl." The compound that forms a saturated solution at 40 degrees C that contains 46 grams per 100 grams of water is the NH4Cl. <span>Ammonium chloride is an inorganic compound with a white crystalline salt that is highly soluble in water.</span>
The molecular weight of NaCl is 58.5 g/mol. 737 g/58.5 g/mol = 12.6 mol. So, there are 12.6 moles of NaCl in the box.
Given what we know about the mechanisms surrounding weather, we can confirm that Large deserts receive less rainfall due to the lack of bodies of water and "rainshadows".
- Rainshadow is a term used to describe the effects of nearby mountains on the rainfall amounts of a desert. The mountain causes the air to rise greatly and lose moisture. This moisture is received by the mountain, <em><u>which means that it does not reach the desert area. </u></em>
- Another limiting factor for the amount of rainfall received by deserts is the lack of bodies of water in the area. Once a desert is formed, <em>it tends to lack large bodies of water</em>. This limits the rainfall it receives given that there is no water nearby to evaporate and <em><u>cause the formation of clouds. </u></em>

1) The nucleus of an atom loses 2 protons and 4 neutrons.
2) The nucleus of an atom gains a proton and it's neutrons remain the same.
C4H10 (g) + (6.5) O2 (g) --> 4CO2 (g) + 5H2O (g)
Smallest coefficient of C4H10 is 1.
First, balance out the Carbon and Hydrogen atoms as they are limiting.
Second, calculate the number of Oxygen atoms and minus away those found in C4H10.
Divide the number with 2 as oxygen exists as O2. [It is OK to put a fraction in front of the molecule as long as there is 1 atom used in the reaction. ]
