In a 1-l beaker, 213 ml of 0.345 m ammonium chromate was mixed with 107 ml of 0.227 m chromium(iii) nitrite to produce ammonium nitrite and chromium(iii) chromate. write the balanced chemical equation for the reaction occurring here. (use the lowest possible coefficients. use the pull-down boxes to specify states such as (aq) or (s). if a box is not needed, leave it blank.)

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.

Which answer tells the reason the earth’s climate is getting warmer? too many animals are becoming extinct. large glaciers are melting in antarctica. the earth is moving closer to the sun. driving cars gives off gases that trap heat in the atmosphere.
