The specific heat capacity of silver is 0.24 J/g °C. How many joules of energy are needed to warm 0.500 g of silver from 25.0°C to 27.5°C?

0.3 J

Explanation:

The equation for heat capacity is Q = mcΔT where Q is the heat, m is the mass of the substance, c is the specific heat capacity of the substance and delta T is the change in temperature. Plugging those values into the equation, we have Q = (.500)(0.24)(27.5-25) = 0.3

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
