Description

From the listing uploaded by “appupdater”.

Practice chemistry, check your answers and understand how to solve chemistry problems step by step. Chemistry: Exercises Generator is designed for high school and college students who want to learn chemistry, prepare for a test or exam, do homework, or improve their ability to solve chemistry exercises. Generate a new random chemistry exercise, try to solve it yourself, then reveal the answer and the complete solution. You can practice as many exercises as you need and use the app to check whether your solution is correct. Results and solutions are hidden at first, so you can try solving each exercise yourself before checking the answer. Every exercise includes full solution steps and a short theoretical introduction to the topic. You can also enter your own data and let the app solve the exercise for you. This is available for most topics and is useful when you have a particular chemistry problem to solve, want to check your calculations, or want to understand how a specific exercise should be solved. With data input, you are not limited to the exercises randomly generated by the app. Enter the values from your own exercise and get the result together with the full solution steps. This makes the app useful both for practicing chemistry and for solving and checking your own chemistry exercises. If you are a teacher, you can also use the app to quickly prepare exercises, homework assignments or test questions for your students. Chemistry: Exercises Generator has more than 40 chemistry topics across a range of chemistry domains, including: balancing chemical equations, calculating the mass of reactants and products, molar concentration, half-life and many more. The app covers the following areas of chemistry: - atoms and molecules, - fundamentals of stoichiometry, - chemical reactions, - solutions, - dissociation, - hydrates, - electrochemistry, - electron configuration, - radioactivity.
