Explain why ionic components are formed when a metal from the left side of the periodic table reacts with a non-metal from the right side. give two examples of each
You are asked to prepare 150 mL of a 0.059 M solution of silver nitrate. How many grams of silver nitrate do you need to weigh out.
if 0.200mole of NaOH is added to 1 liter of solution that is 0.100M in aqueous ammonia and 0.200M in ammonium chloride how much does the Ph change.
C2H5OH(aq)+2Cr2O7^2-(aq)+16H+(aq)---> 2CO2(g)+4Cr^3+(aq)+11H2O(l) What is the blood alcohol level in mass percent if 8.26mL of 0.04988 M K2Cr2O7 is required for titration of a 10.005g sample of blood?
CaC2 + 2H2O --> C2H2 + Ca(OH)2. Using this equation, determine how many moles of CaC2 are needed to react completely with 49 g H2O.
In a chemical reaction (unbalanced equation), AsF3 + C2Cl6 -> AsCl3 + C2Cl2F4, the theoretical yield of C2Cl2F4 was calculated to be 1.86 mol. If the percent yield in the reaction was 77.2%,

Gaseous indium dihydride is formed from the elements at elevated temperature: In(g)+H2(g) (reactions goes both ways=double arrow) to InH2(g) with Kp=1.48 at 973 K
Sketch a cube. How many vertices does it have? How many edges? How many faces? Mark four vertices of the cube that are also vertices of a regular tetrahedron.
if 8.6L of H2 reacted with 4.3L of O2 at STP, what is the volume of the gaseous water collected (assuming that none of it condenses)?2H2(g)+ O2(g)--> 2H2O(g
