College chem! phosphoric acid, h3po4, is a triprotic acid found in some soft drinks such as coca-cola (shown in the photo at the start of this chapter) where it adds a
touch of tartness to the beverage. write equations for its stepwise ionization in water. include states in your answer.

An atom of lithium-7 has an equal number of(1) electrons and neutrons(2) electrons and protons(3) positrons and neutrons(4) positrons and protons

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
