# What is the balanced equation for Heating tin IV hydroxide gives tin IV oxide and water?

Sn(OH)4 ---> 2H2O + SnO2

### Why is the following equation invalid Al 2O2 --- Al2O3?

Because the numbers of aluminum and oxygen atoms are not the same on both sides of the equation, so the equation is not balanced. In order to be balanced, the numbers of atoms of each element must be the same on both sides of the equation. The correct equation is 4Al + 3O2 --> 2Al2O3. This gives 4 aluminum atoms and 6 oxygen atoms on both sides of the equation, so it is balanced.

### Why must chemical equations always balance?

Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced…

### What is the balanced equation of the hydration of CuSO4?

A hydration equation gives information regarding the reactants and products formed when a substance dissolves in water. Since a hydration reaction takes place in water, the solvent water can be indicated above the arrow. For example, the hydration equation for a strong electrolyte, such as , can also be written as Similarly, the hydration equation for a weak electrolyte, such as , and a nonelectrolyte, such as , can be written as

### What does the formula below represent CO2 plus H2O plus energy gives C6H12O6?

This is NOT a formula. CO2 and H2O are formulas. What you have here is part of the equation for photosynthesis. It should be written wholly in words, or as a completely balanced chemical equation, it doesn't work if you mix them. carbon dioxide + water (plus energy) --> glucose + oxygen 6CO2 + 6H2O --> C6H12O6 + 6O2 It is not done to include energy in the balanced symbol equation, because it is not…
