Na+ and C2H3O2- (acetate) don't react.
Only Ag+ and Cl- do so by precipitation:
Ag+ + Cl- --> (AgCl)s
you have to write... 2KI + Cl2 = 2KCl + I2
First you have to write the entire equation (including states): CuSO4(aq)+ 2NaOH(aq) -> Cu(OH)2(s) + Na2SO4(aq) Now you have to write an ionic equation which involves splitting up each compound, that is in aqueous form, into it's parts and writing the charge of each part: Cu(aq)2+ + SO4(aq)2- + 2Na(aq)1+ + 2OH(aq)-1 -> Cu(OH)2(s) + SO4(aq)2- + 2Na(aq)1+ Now to write the net ionic equation, you "cancel" out any thing that is the exact same on both sides of the equation (same state, number, charge). That leaves us with the following: SO4(aq)2- + 2OH(aq)-1 -> Cu(OH)2(s) This is the net ionic equation.

The equation for the dehydration of sodium carbonate decahydrate (washing soda) is: [ Na2CO3 · 10H2O \rightarrow Na2CO3 + 10H2O ]
A chemical reaction is a process that results in the transformation of chemical substances into new substances with different properties. A chemical equation represents this reaction using chemical formulas of the reactants and products, along with their respective coefficients to balance the equation.
hnc7h4so3 + h2o --> nc7h4so3- + h3o
That IS the equation. You may want to write with the equal sign: 6p = 24
-- take two quantities that are equal to each other -- write them both on the same line, with an "equals" sign between them ( = ) You now have an equation.

-9p - 15 = 93
There are no "following" data!
4x+8y=-24
It's not an equation - there's no "is" or "equals." You can write it as a mathematical *expression*, however:140 "decreased by 20%"140 - (20/100)*140
5x-4y=8
You cannot because it is not true.
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
