What is the specific heat of an unknown metal of 2.93 kcal of energy are required to raise the temperature of 183.4g sample of the metal by 126.3 Celcius

The specific heat of the unknown metal is 1.26*10⁻⁴

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat occurs when heat added or removed from a substance causes a temperature change in it and is calculated by:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT (Tfinal - Tinitial) is the variation in temperature

In this case:

Replacing:

2.93 kcal= c* 183.4 g*126.3 °C

Solving:

c= 1.26*10⁻⁴

The specific heat of the unknown metal is 1.26*10⁻⁴

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
