Use the following scenario to answer the question. Antonio is experimenting with solutions. He takes a large beaker of distilled water and dissolves salt, and then sugar. Has Antonio created a solution or a mixture? If it is a solution, identify the solute(s) and solvent(s). (1 point) By combining three ingredients, Antonio made a mixture. Solutions can only consist of one solvent and one solute. Antonio dissolved salt and sugar in water to form a solution. Solutions can have many solutes, but only one solvent In this mixture, salt and sugar are solutes, and water is the solvent. By dissolving salt and sugar in water, Antonio made a solution Solutions can have many solvents, but only one solute. In this solution, salt and sugar are solvents, and water is the solute. Antonio created a mixture because solutions can only have one solvent, but he used salt and sugar as solvents

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
