Answer:

Double-Replacement Reaction

Explanation:

Mg is Oxidized, and O2 is the cause of the oxidation, hence the Oxidizing agent. That means that O2 is Reduced and Mg is the cause naming it the Reducing agent.

What would be the final temperature of a 73.174g sample

madreJ [45]

The final temperature is -138 °C.

Explanation:

Using the equation of specific heat

$Q = m*c* del T$

We can easily find the final temperature of a 73.174 g of copper sample. As we know that specific heat is the amount of energy required to raise the temperature of the object to 1°C.

The specific heat of copper is known as 0.387 J/g°C and the initial temperature is said as 102 °C . The mass is given as 73.174 g. The heat released is 6800 J.

Since the heat is released the Q value will be negative.

$-6800=0.387*73.174*(T_{final}-102)$
