A student was investigating the rate of reaction between a solid base and a solution of sulfuric acid. Two experiments were performed, S and T, in which the mass of the
reaction flask was recorded as shown in the graph.

Which of the following changes could explain the difference in results between S and T?

A ) The sulfuric acid is less concentrated in T.

B ) The sulfuric acid is more concentrated in T.

C ) A higher temperature is used in S.

D) Larger sized particles are used in T.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

i think its 5049.

i hope this !

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
