Calculate the change in energy (ΔH) in joules for the system. The reaction absorbs 150 J of energy and does 25 J of work on the syringe.

Fill in the missing numbers in the equation [tex]\( Q + W = \Delta H \)[/tex]:

[tex]\[ 150 \, J + 25 \, J = \Delta H \][/tex]



Answer :

To solve this problem, we need to determine the change in energy of the system, denoted as [tex]\(\Delta H\)[/tex].

We are given the following information:
- The energy absorbed by the reaction, [tex]\(Q\)[/tex], is [tex]\(150\)[/tex] joules (J).
- The work done on the syringe, [tex]\(W\)[/tex], is [tex]\(25\)[/tex] joules (J).

The formula to calculate the change in energy ([tex]\(\Delta H\)[/tex]) is given by:
[tex]\[ Q + W = \Delta H \][/tex]

Let's fill in the given values:
[tex]\[ 150\ J + 25\ J = \Delta H \][/tex]

Now, let's add these values together to find [tex]\(\Delta H\)[/tex]:
[tex]\[ 150\ J + 25\ J = 175\ J \][/tex]

So, the change in energy of the system, [tex]\(\Delta H\)[/tex], is [tex]\(175\)[/tex] joules.

Thus, the completed equation with the missing numbers is:
[tex]\[ 150\ J + 25\ J = 175\ J \][/tex]
