Heterogeneous mixtures - Study guides, Class notes & Summaries

1 kilogram (kg) of solid X at 10°C and 1 kg of solid Y at 10°C each absorb 5 joules of heat energy. The final temperatures of X and Y are 15°C and 20°C, respectively. Compared to X, Y must have a lower specific heat. conductive heat. heat of fusion. heat of vaporization. - Answer-specific heat. A drop of dilute ammonium hydroxide (NH4OH) is placed on one side of a slide containing a large number of swimming paramecium. Under this condition, which of these behaviors of the paramecia wi...

Chemical properties Chemical properties describe the characteristic ability of a substance to react to form new substances. Physical properties Physical properties are characteristics that can be measured without changing the composition of the sample under study Elements contain only one type of atom Mixtures contain more than one type of molecule Compounds Contain more than one type of atom, but only one type of molecule Heterogeneous Mixtures mixtures that are not uniform and so di...

Determine density. Write the formula. What is the density of an object that has a mass 40.0g and a volume of 8.0mL? Show your work. Answer: D=m/v (mass/volume) 40/8= 5g/mL What is the density of water? Would the object in #1 float or sink in water? Explain. Answer: The density of water is 1g/mL the object in #1 would sink because an object with a density less than 1 g/cm3 will float What are two ways that mixtures are classified? Give an example of each. Answer: heterogeneous: Oil ...
