What is the answer to the following calculation? 2(5+10)/3
PEMDAS: Parentheses, Exponents, Multiplication/Divison, Addition/ Subtraction First, let's begin with the numerator, we have to solve what is inside the parentheses. (5+10)=15 Then we must multiply the 2 outside of the parentheses by 15 = 30 Lastly, we must divide by 3... 30/3= 10 The answer is 10.
Subject: Basic Chemistry
Define and write out the molecular, ionic, and net-ionic equations for the following reaction: KCl is added to Pb(NO3)2
Molecular Equation: gives overall reaction: 2KCl (aq)+Pb(NO3)2 (aq) --> 2KNO3 (aq) + PbCl2 (s) Ionic Equation: includes all ions in solution including spectator ions: K+ + CL- + PB2 + NO3- --> PbCl2 (s) + K+ + NO3- Net-Ionic Equation: only gives information on those species that undergo a chemical change: Pb2+ + 2Cl- --> PbCl2
