A 140 g zinc block initially at 85C is placed inside a calorimeter that has 20 g of water initially at 15C A. Which is gaining energy? which is losing energy? explain for both
B. Will the energy gained be the same as the energy lost? why?
C. Will the change in temperatures for each substance be the same? explain.
D. If thermal equilibrium block initially at 37C, verify part B by solving for energy for each substance. (round answers to the nearest or whole number)

idk heheheheh

Explanation:

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
