中学化学式クイズ

This is a quiz game about chemical formulas learned in junior high school science classes. You can learn about simple substances (hydrogen, oxygen, carbon, gold, etc.) and compounds (water, carbon dioxide, hydrogen chloride, etc.) that eighth graders learn in science class. Since it is divided into input and output, you can challenge even from zero knowledge. In the input, after confirming the substance name and chemical formula, a simple two-choice test is performed. In the output, we will challenge the four-choice question. The number of inputs and outputs and the correct answer rate are recorded on the smartphone and evaluated with a star mark. Try your best to get 5 stars.
