Hot lead with a mass of 200.0 g of ( specific heat of Pb = 0.129 J/g ° C) at 174.4° C was dropped into a calorimeter containing an unknown volume of water. The temperature of the water increased from 21.7° C to 56.4° C. What volume of water is in the calorimeter?

anaphase.

hope this !

i would say b

explanation:

but i think i would need more information than that

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.
