The image contains a series of chemistry questions related to chemical reactions and composition. Below is a transcription of the text: --- **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, \( H_2SO_4 \), was found to contain 32.4g of sulfur, S. What is the percent by mass of sulfur in the sample?** --- **10) In a round-bottom flask, a chemist completely reacts 4g of hydrogen with 25g of chlorine. What is the percent by mass of hydrogen in the compound that was formed?** --- **11) Two unknown compounds are tested to determine their composition. Compound A was found to contain 16g of magnesium and 130g of sulfur. Compound B contains 9g of magnesium and 63g of sulfur. Are these the same compound? Explain your answer.** --- **12) A chemical analysis of two unknown compounds found that they are both made up of only calcium and oxygen. During an analysis of their mass, it was found that they both contain the same percent by mass of calcium. However, the instrument used in the analysis broke before the mass of oxygen could be determined. With only the information that is known, can you be sure that both compounds are the same?** --- This series of questions covers various aspects of chemical reactions, including the appearance of compounds, percentage composition, and the determination of compound composition.

Sure! Here's the transcription for the educational website: --- ### Chemistry Problems 2) **Ammonia Synthesis** A chemist is attempting to synthesize, or create, ammonia (NH₃) in the laboratory. He reacts 14.6 g of nitrogen (N) with hydrogen gas (H) to form 27.9 g of ammonia (NH₃). Determine the mass of hydrogen that was used in the reaction. 3) **Desert Water Formation** A chemical supply truck breaks down in the desert, and the driver is running out of water. He is at risk of dying from dehydration but remembers what he learned in chemistry class. He decides to use some of the chemicals he is carrying to form water that he would be able to drink. He ultimately reacts 13.8 g of hydrogen (H) with 8.8 g of oxygen gas to form drinkable water (H₂O). How much water did he create in his reaction? 4) **Splitting Uranium Hexafluoride** An evil scientist is attempting to split up uranium hexafluoride (UF₆) into its component elements, uranium (U) and fluorine (F). Once the process was complete, he was left with 70.5 g of uranium and 36.3 g of fluorine. What mass of the original uranium hexafluoride (UF₆) did he have? 5) **Hydrochloric Acid Decomposition** A student in a chemistry class made a mistake and used a device that she was explicitly asked not to use. The device broke apart 42.1 g of hydrochloric acid (HCl) into hydrogen gas (H₂) and 26.9 g of chlorine (Cl). How much hydrogen gas was produced during this process? --- No graphs or diagrams are included in the text provided.
