Please help with net ionic equations, I don't get how to do them!

Can someone please show me how to write a net ionic equation for this, like step by step....thank you sooooo much! K2S+Pb(SO4)2 --------------->-I think you’ve copied the question incorrectly Accor

Are atomic wedgies actually possible

Like the ones where the waistband goes over your head???-ONly with uranium can an atomic wedgie be successful

Pls explain Markovnikov Rule

what is Markovnikov Rule and why is it important? thank you!-In addition reactions to unsymmetrical alkenes, the electron-rich component of the reagent adds to the carbon atom with fewer hydrogen atom

Balancing redox reactions

The very first step in balancing redox reactions is to split up the reaction into one of oxidation and one of reduction. So....... O2 + Sb ----> H202 + SbO2^1- (SbO2s charge is minus 1. Im just not s

How can I convert percent composition by mass to molarity? Specifically, 4% H2O2 to molarity

In a solution of 4% H2O2, there is 4 part H2O2 and 96 part H2O by mass. Assume 100 gram solution. Therefore the solution contain = 4/MrH2O2 = 4/34 = 0.118 mol of H2O2. for water, you can assume the

Are there smaller particles then electrons and neutrons

Does the smallest particle exist, if so, from what is it made? THANKS FOR EVERY ANSWER-Protons and neutrons appear to be made of smaller particles called quarks. Theoretical physics suggests the small

Is this a safe thing to do

In Chemistry class, we are learning about how substances kill certain bacteria. Well, this came to mind. Acids with a very low pH (below 1) kill 100% of bacteria. So when you take a bath, the purpose

What is the partial pressure (in mmHg) of argon in a 5.00 L vessel that contains 0.757 mol of methane, 0.210 mol of ethane and 0.810 moles of argon at a total pressure of 875 mm Hg?-(0.810)/(0.810+0.7

If your good at chemistry please help me with these equations

Im just checking my answers I want to make sure I have a 100%. I screen shot it so it would be easier to read. Thanks in advance. Theres 5 but you dont have to do all if you dont want. I would be than

Is this net ionic equation correct? (#2!)

I have a molecular equation of: CaCo3 (s) + 2HCl (aq) ---> CaCl2 (aq) + CO2 (g) + H2O (l) Im not sure if when writing the net ionic equation, I break down the CaCO3 or not, as its a solid.Ive seen b
