8) A chemistry student reacts a black metallic element with an element that exists as a bright blue powder. What will the resulting chemical compound look like? A) The compound will appear mostly black since the color black will overpower the bright blue color. B) The appearance of the chemical compound is not dependent on the color of the original elements. C) The color of the resulting compound will be a mixture of black and bright blue, leaning mainly towards the color black. D) The color of the resulting compound will be a mixture of black and bright blue, leaning mainly towards the color bright blue. 9) A 98.4g sample of sulfuric acid, H;SOa, was found to contain 32.4g of sulfur, S. What is the percent by mass of sulfur in the sample?

The brilliance with which magnesium burns makes it ideal for use in marine flares and fireworks. Compare the mass of magnesium that burns with the mass of magnesium in the magnesium oxide ash that forms. Explain this in terms of atomic theory. The white light in fireworks can result from burning magnesium.

One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.
What are some of the physical properties that distinguish the metallic element from the nonmetals? Are these properties absolute, or do some nonmetallic elements exhibit some metallic properties (and vice versa)?
