D) Explain, in terms of particles, how and why the rate of reaction changes during the
reaction of calcium carbonate with hydrochloric acid.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
