(01.04 MC) An ice cream sundae was left outside in the sun before it was
eaten. The ice cream sundae had chocolate chips, whipped cream,
and strawberries. The total mass of the ice cream sundae was 500
grams. Which best describes what happens to the mass of the
sundae? (1 point)
When the ice cream melts it will trap air which will make the sundae
heavier.
As the ice cream melts into a liquid, the liquid will evaporate, making
the sundae lighter
After the sundae melts into a liquid the mass will be greater since
liquids have a greater mass.
The mass of the melted sundae will be the same as the mass of the
frozen sundae.

Help me!!!

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

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
