## How do you tell if a chemical equation has no reaction?

Write another chemical equation you want to analyze; for example, the combination of sodium chloride (NaCl) and calcium nitrate (Ca[NO3]2): “NaCl(aq) + Ca(NO3)2(aq) –> NR.” Remember that “NR” means “no reaction.”

## What math do I need to know for chemistry?

A solid understanding of algebra, trigonometry and diffrentiation/integration is necessary. More advanced topics which may be useful include partial derivatives, solving simple first and second order differential equations, solving partial differential equations, group theory, Fourier transforms.

## How can I learn chemistry quickly and easily?

How To Study for Chemistry

- Review and Study Material Before Going to Class.
- Seek Understanding.
- Take Good Notes.
- Practice Daily.
- Take Advantage of Lab Time.
- Use Flashcards.
- Use Study Groups.
- Break Large Tasks Into Smaller Ones.

## How do you equalize an equation?

Basically, the method of equalizing consists of:

- Clear an unknown in one of the equations, which will depend on the other unknown (we will continue to have an equation).
- Clear the same unknown in the other equation.
- Equalize the second members of the two unknowns, forming a new equation with an unknown one.

## What is a chemical equation class 10?

Chemical Equation: Representation of chemical reaction using symbols and formulae of the substances is called Chemical Equation. (a) Balanced Chemical Equation: A balanced chemical equation has the number of atoms of each element equal on both sides.

## What are stoichiometric defects?

The compounds in which the number of positive and negative ions are exactly in the ratios indicated by their chemical formulae are called stoichiometric compounds. The defects do not disturb the stoichiometry (the ratio of numbers of positive and negative ions) are called stoichiometric defects.

## What is stoichiometry coefficient?

The stoichiometric coefficient is the number written in front of atoms, ion and molecules in a chemical reaction to balance the number of each element on both the reactant and product sides of the equation. Though the stoichiometric coefficients can be fractions, whole numbers are frequently used and often preferred.

## What is a mole in chemistry?

Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
