Chemistry is to do more with Labs and Lab reports as it is the most essential part of the subject. As most of your grades are dependent on the lab reports one must come up with an outstanding report considering all requirements of the topic.

Our tutors help you write a report by providing you complete necessary explanation   and help you decide what to include in various parts of the report. Problem solving is a skill which is not explicitly taught during lectures. The best way to master how to solve chemistry problems is to practice the problems you have answers to.
Few steps you can follow before solving Chemistry problems are:

1) Make a note of the chemical concepts denoted in the problem

2) List the known values and represent them with appropriate symbols

3) Define the unknown and use appropriate symbol to represent them with symbols

4) Write down the equations required to solve the problem

5) Apply the known values in the equation and solve for the same
In order to solve chemistry problems and compute to find the right equation. One must always make a note of clear and concise record and important terms to review them quickly before attending an examination. Understand and be thorough with chemical names so as to identify them and avoid mistakes during an examination. At any time if you’re confused ensure that you ask your tutor immediately and solve the query without proceeding further. Don't be afraid to ask for help. In that way Chemistry can both be fun and challenging.
