I’ll give you NaCl but not all of them
<u>Answer:</u> There are 8 hydrogen atoms on the product side in the reaction.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This law also states that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balance chemical equation follows:

<u>On reactant side:</u>
Number of Phosphorus atoms = 1
Number of Chlorine atoms = 5
Number of Hydrogen atoms = 8
Number of Oxygen atoms = 4
<u>On Product side:</u>
Number of Phosphorus atoms = 1
Number of Chlorine atoms = 5
Number of Hydrogen atoms = 8
Number of Oxygen atoms = 4
Hence, there are 8 hydrogen atoms on the product side in the reaction.
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

Answer:
There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst. 4. Reduce pressure way below the limit 269 kPa.
