1. Classify the following statement “In a chemical reaction between two reactants, the excess reagent will be the reactant with the larger mass” as a) always true b) never true c) sometimes true (Record your answer with rounded answer to proper significant digits and the proper units.) 2. Dinitrogen pentoxide reacts with water as represented in the following reaction.N2O5(s)+H2O(l)------>2HNO3(l) If 0.139 g of N2O5(s) were reacted with 0.0550 g of water, how many milligrams of HNO3(l) would be produced? Hint: Determine limiting reagent first. 3. When 7.34 mol of methane burns in excess oxygen gas, what volume of CO2(g) at STP is produced? Hint: Write a balanced chemical reaction equation first.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
