What is the general procedure for solving a stoichiometric problem?
You can write a series of simultaneous equations, one for each type of atom. For example, in the reaction to produce water: aH2 + bO2 --> cH2O, you want to find out the coefficients a, b, and c, so you write the following equations: For atom H: 2a = 2c For atom O: 2b = c Note that you only have two equations, for three unknowns. This is common in this case; after all, you won't find out, in absolute terms, how much of each reactant you need; only the relationship between them. Solving the equations, you get the relative amounts of the substances.
How many milliliters of 0.200M H2SO4 will neutralize 40.0 mL of 1.50M KOH?
Let's solve this problem without using specific numbers as that's more instructive (and won't give away an answer to someone's homework problem).The question is:What volume Vacid of strong diprotic acid solution of molarity Macid is needed to neutralize a volume Vbase strong base solution of molarity Mbase?So, Macid, Vbase, and Mbase are known and we are asked to find Vacid.A strong base of the form BOH will completely dissociate in solution into B+ and OH- ions, so Mbase is the same as MOH- in this problem.A strong diprotic acid of the form AH2 will lose both of its protons in the presence of OH- ions to form A2+ and two H+ ions, so Macid is half of MH+ in this problem.Neutralization is the process of mixing an acidic solution with a basic solution in proportion such that the number of OH- ions in the basic solution is equal to the number of H+ ions in the acidic solution. To get the number, you must multiply the ions' molarity times there volumes.So, we need:MH+·Vacid = MOH-·Vbaseor2·Macid·Vacid = Mbase·Vbase (since Macid is half of MH+ and Mbase equals MOH-)solve for Vacid to obtainVacid = (Mbase·Vbase)/(2·Macid)
What does red light do for a plant?
In red light, I plant will still grow perfectly fine, if not better. Think of it this way. The chlorophyll in a plant is green. This means that it reflects green light and absorbs all other light. So it would absorb Redlight just as easily, if not better than white light, which contains green. The only color light that will not help a plant is green light.

God did not create this but in truth. He explains the verses in detail for people who have knowledge.
