Exercise Fill in the blank.
1. Sublimation is a change from the solid phase to the phase.
2. Boiling point is an (intensive, extensive) property.
3. Deposition refers to a change from the phase to the solid phase.
Respond to the following based on your reading.
mass
4. The equation for density is d = Mass and volume are extensive
volume
properties. Is density intensive or extensive? Explain your choice. [1]
5. A certain solution has a density of 1.1 g/cm3. What is the volume of 43 g of
this solution?
6. Gasoline is more volatile than water. What does this tell you about the boiling
points of water and gasoline?
7. A graduated cylinder is filled with water to the 20 ml mark. After an object is
submerged in the liquid, the volume of the liquid is 28 ml. If the object weighs
16 g, what is the density of the object in g/cm??

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light

How many moles are in 7.2 x 10^23 carbon molecules? (*round to the nearest hundredth and include the unit "mol c" after your number) question 6 options:

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
