Stoichiometric equations - Study guides, Class notes & Summaries

● Stoichiometry is the use of quantitative relationships between substances that are involved in chemical reactions which determine the amounts of the reactants or the products (Bauer, Birk, & Mar ks, 2019). Stoichiometry - the process of determining the amounts of substances in a chemical reaction (Bauer, Birk, & Marks, 2019). ● It is used to relate the reactants and products by using calculations and balanced equations (Bauer, Birk, & Marks, 2019). ● By knowing the amount of a reactant o...

Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...

Asked to find volumetric flow rate of gas - what equation could you use? Correct Answer: PV=mRT - Pv=RT - V(rate) = m(rate)*R*T/P====remember v=V(rate)/m(rate) How do you calculate feet of air from inches of H20? Correct Answer: Convert inches of H20 to feet of H20 and then multiply by (density water/density air) - counterintuitive. What is a good way of manipulating the equation for velocity through a pitot tube in handbook? Correct Answer: v=(2g(p0-p1/y))^1/2 can be changed to v= (2gh)1...
