Ответ:
Temperature change would be 112.6° C.
Explanation:
We can find the amount or heat absorbed or emitted during any reaction by finding the product of their mass, specific heat, and change in temperature of the metal.
Mass of the iron, m = 50.0 g
Amount of heat absorbed, q = 2500 J
Change in temperature, ΔT = ?
Specific heat of Iron, C = 0.444 J/g °C
Plugin the values and rearrange the equation to get the change in temperature as,
Ответ:
That means there will be s and p shells present in the atom. As the values of both l and n are fixed. Therefore, electrons will be present in same level and same sub-shell.
