To balance the equation, you need to have equal numbers of atoms on both sides. In this case, you have an unequal number of hydrogen atoms. To balance it, you can add water (H2O) to the products.

So, the correct answer is H2O.

Answer 4

The image shows a model of sulfuric acid. In the middle is one yellow ball. Four red balls are attached to the yellow ball with sticks. Two of the red balls have a blue ball attached with sticks. In total, there is 1 yellow, 4 red, and 2 blue balls.

The image is a model of sulfuric acid that has a chemical formula of H2SO4. In 1-2 sentences, explain why creating models, like the one shown in the image above, is important in understanding substances.
