- Container A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in (a) Container A in grams? (b) Container B in grams?arrow_forwardName the SI base units that are important in chemistry,and give the SI units for expressing the following:(a) length, (b) volume, (c) mass, (d) time, (e) temperature.arrow_forwardA metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL. (A) How much water does the metal displace? (B) Calculate the density of the metal. (C) Is the metal made of platinum? Explain. (Hint: the density of platinum = 21.4 g/cm³)arrow_forward

Match the statement with the appro- priate step (observation, hypothesis, experiment designed to test hypothesis) in the scientific method. (a) A metal is burned in a closed container, and the change in mass of the solid and volume of the gas is measured.(b) Oxygen gas combines with a substance during its combustion.(c) Combustion of a metal in a closed container ceases after a length of time.arrow_forwardWhich of the following processes is a physical change? (a) evaporation of water; (b) combination ofhydrogen and oxygen gas to produce water; (c) dissolution of sugar in water; (d) separation of sodium chloride (table salt) into its constituentelements, sodium and chlorine; (e) combustion of sugar to produce carbon dioxide and water.arrow_forward
- Sodium and potassium are both shiny metals in pure form, but corrode rapidly in the presence of oxygen and humidity to form compounds. Does this fact describe a physical or chemical property of these two metals?arrow_forwardClassify each property as physical or chemical.

When one person did so, she found that she inhaled 3.62x10^22 molecules of the mixture of mostly nitrogen and oxygen we call air. Assuming this mixture has an average molar mass of 29.0 g/mol, what is her apparent lung capacity in grams of airarrow_forward
