Activity b (continued from previous page)
vec reset set the water temperature to 100 cand the
vater temperature to 100c and the ice volume to 50 cm
play how does the situation compare to the previous one
dose a theory: based on what you have observed, explain why you think phase changes
ecur it possible discuss your theory with your classmates and teacher.
apply use your theory to explain what happens at the molecular level in each of the
following situations. also, list the temperature at which each transition occurs.
a
lce is warmed to the melting point.
temperature:
b. water is warmed to the boiling point.
temperature:
c water is cooled to the freezing point.
temperature:
8. extend your thinking: click reset. set the water temperature to 0 °c, the ice volume to
o cm. and add/remove heat energy to -400 j/s. click play and wait until all of the water
freezes
a. what volume of ice is created from 200 cm
of water?
b. why do water pipes sometimes burst in the winter? gizmo phase changes

What is the polyatamic ion of thiosulfate

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

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
