The probability of compound events refers to mathematical formulas and methods that are used to find out the likelihood that two independent events will happen.

<h3>What is compound probability?</h3>

Your question is incomplete so instead, I'll give an overview of compound events probability.

Compound events refer to independent events so when we look for compound event probability, we are trying to find out how possible it is that both these independent events happen.

The simplest method is by multiplying the probabilities of these two events with the product being the compound probability.

Suppose that 3. 33 g of acetone at 25. 0 °c condenses on the surface of a 44. 0-g block of aluminum that is initially at 25 °c.

Vlada [557]

The final temperature on the block is 25 degrees.

Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.

Data given;

M1 = 3.33g
T1 = 25 degrees
M2 = 44g
T2 = 25 degree
C1 = 124.5 J mol K
C2 = 0.89 J/g K

<h3>Heat Transfer</h3>

Applying the principles of heat transfer,

Heat loss = Heat gain

$m1c1(T1 - T3) = m2c2(T3 - T2)\\3.33*124.5*(25.0 - T3) = 44*0.89*(T3 - 25)\\10364.625 - 414.585T3 = 39.16T3 - 979\\10364.625+979 = 414.585T3 +39.16T3\\11343.25 = 453.745T3\\T3 = \frac{11343.25}{453.745} \\T3 = 24.999\\T3 = 25$
