A student mixes magnesium and hydrochloric acid and a chemical reaction occurs, shown in the equation below. ____ Mg + _____ HCl --------> _____ H2 + ______ MgCl a. Balance the chemical equation, then label the reactants and the products. b. What do the coefficients in the chemical equation represent? c. What does it mean if an element or molecule does not have a coefficient? d. How many moles of magnesium would you need for the reaction if you had 2 moles of HCl? e. How many moles of magnesium would you need for the reaction if you had 4 moles of HCl? f. How many moles of hydrogen gas (H2) would be produced if you started with 2 moles of magnesium and 2 moles of hydrochloric acid (HCl)? g. If you started with 2 moles of magnesium and 6 moles of hydrochloric acid (HCl), which one would be your limiting reactant? Which one would be your excess reactant? h. Using the information from part e, how many moles of hydrogen gas (H2) would be produced if you started with 2 moles of magnesium and 6 moles of hydrochloric acid (HCl)? How many moles of reactant would be leftover?
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.
