When entering coefficients to balance equations recall that just writing the symbol implies 1. Therefore if a coefficient of 1 is required choose blank for that box. Balance the following reaction. Al?

The balanced equation is: 4Al + 3O2 → 2Al2O3.


Why caution is required when the homogeneity of an equation is being tested?

Caution is required because even if an equation appears homogeneous, it may not be so upon closer inspection. The order and function of the variables in the equation need to be carefully considered to determine homogeneity accurately. Failure to do so can lead to incorrect conclusions and solutions.


Is it necessary to write an equation when no reaction occurs?

If no reaction occurs between the substances, then there is no need to write an equation. Equations are used to represent chemical reactions, so if no reaction is taking place, an equation is not required.


Why are there 4 NH3s in the following equation Cu2 plus (aq) plus 4 NH3(aq) Cu(NH3)42 plus (aq)?

The coefficient of 4 in front of NH3 in the balanced equation indicates that four ammonia molecules are required to form a complex ion with copper ions. This balanced equation ensures conservation of mass and charge in the reaction.


How many grams of oxygen are needed for the complete combustion of the butane in the lighter?

The variables for the formula are incomplete. You would need to know how many grams of butane are put out by the lighter. The molecular weight of butane is 58.12 g/mol, which is also needed to complete the formula.

Find the derivative of an equation?

A more complete question is required to receive a good answer here. If you were to ask how to derive a function, I could take you through a general rundown of the basic derivative patterns of most common functions. Since you said "equation" though, this implies the possibility of implicit differentiation methods being required. If you were to narrow down your question more, you might get a better answer.

What are the steps on solving equations?

The answer will depend very much on the nature of the equation. The steps required for a one-step equation are very different from the steps required for a partial differential equation. For some equations there are no straightforward analytical methods of solution: only numerical methods.
