Question

6,210 j of energy was transferred from the water and 127 j of energy was transferred from the calorimeter to the lithium sample. what was the total energy change for the lithium?
$q_{lithium} = ? j$
enter either a + or - sign and the magnitude.

Explanation:

Step1: Identify energy transfer direction

Energy is transferred to the lithium from water (6210 J) and from the calorimeter (127 J). So lithium gains energy, which means a positive change.

Step2: Sum the energies

To find total energy change for lithium, add the two energy amounts: \( 6210 + 127 = 6337 \)

Answer:

+6337
