Chemical Reaction Trivia Questions

Gold is a natural substance because it is found in nature in its pure form. It is a precious metal that is often found in rivers, streams, and underground deposits. Gold is not man-made or synthetic, but rather a naturally occurring element. It has been used by humans for thousands of years for various purposes, including jewelry, currency, and electronics. Therefore, the correct answer is yes.

fuel burns when it reacts with oxygen.

There are 4 Hydrogens and One Carbon.

The correct answer is Polyester, Bubblewrap, Fibre Glass. These materials are all synthetic, meaning they are man-made rather than occurring naturally. Polyester is a synthetic fabric commonly used in clothing and other textiles. Bubblewrap is a synthetic material made from plastic and is used for packaging and insulation. Fibre Glass is a synthetic material made from fine fibers of glass and is commonly used in insulation, construction, and manufacturing.

The correct answer is C6-H12-06 + 6O2 --> 6H20 + 6CO2. This equation is balanced because there are equal numbers of atoms on both sides of the equation. The coefficient of glucose is 1, the coefficient of oxygen is 6, the coefficient of water is 6, and the coefficient of carbon dioxide is 6. This ensures that there is an equal number of carbon, hydrogen, and oxygen atoms on both sides of the equation.

Carbon monoxide is the correct answer because CO is the chemical formula for carbon monoxide. Carbon monoxide is a colorless, odorless gas that is produced by the incomplete combustion of carbon-containing fuels. It is highly toxic and can be deadly in high concentrations.

When copper is combined with magnesium in a circuit in saltwater, it creates the highest voltage. This is because magnesium has a higher reactivity than copper, meaning it is more willing to give up its electrons. When magnesium reacts with the saltwater, it forms magnesium ions and releases electrons. These electrons flow through the circuit, creating a higher voltage compared to the other combinations listed.

because in water you need 1 oxygen to 2 hydrogen

Silver Sulphate + Potassium is the most reactive because silver is less reactive than copper and zinc, and potassium is more reactive than hydrogen. When silver sulphate reacts with potassium, a displacement reaction occurs, where potassium replaces silver in the compound. This is because potassium is more reactive than silver, leading to the formation of potassium sulphate and silver. This reaction is more likely to occur compared to the other options, making it the most reactive.

When testing a product that will be used by humans, it is logical to first test it on human cells. This is because human cells are the most relevant and accurate representation of how the product will interact with the human body. Testing on plant cells or animal cells may not provide accurate results as they have different biological structures and functions compared to human cells. Therefore, testing on human cells ensures that the product is safe and effective for human use.
