In our example, where propane and oxygen were the reactants, and water and carbon dioxide were the products, which one of the following would be the limiting reactant if we used 10 grams of propane and 30 grams of oxygen? 1. The oxygen
2. In this chemical reaction, there is no limiting reactant.
3. The propane
4. The carbon dioxide

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
