Balance the equations for the formation of cations from neutral atoms A. Ca->(blank)+(blank)
B. K->(blank)+(blank)
C. Sr->(blank)+(blank)
D. Rb->(blank)+(blank)

What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, c2h6? in this reaction, ethane is burned in the presence of oxygen (o2) to form carbon dioxide (co2) and water (h2o). (g)+(g)→(g)+(g)

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?
