Atoms and molecules are very ( large, small, fast ) and therefore we cannot ( count, arrange, sort ) them by hand. Instead, we must ( weigh, decompose, react ) them. We also measure atoms and molecules in a very large grouping known as the ( mole, gopher, squirrel )

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

If 3.00 g of titanium metal is reacted with 6.00 g of chlorine gas, cl2, to form 7.7 g of titanium (iv) chloride in a combination reaction, what is the percent yield of the product?

Compare and contrast physical changes with chemical changes.
