Question
Energy that is associated with the motion of an object is called kinetic energy thermal energy potential energy chemical energy Calculate the change internal energy (Delta E) for a system that is giving off 622 kJ of heat and is performing 105 k J of work on the surroundings. 64.1 k J -74.1 kJ -7.27 kJ 7.00 times 10^2 kJ -9.00 times 10^2 kJ Is Ag paramagnetic or diamagnetic? Diamagnetic Paramagnetic None of the above Give the ground state electron configuration for Br. [Ar]4s^23d^l04p^6 [Ar]4s^23d^l04p^5 [Ar]4s^24p^6 [Ar]4s^24d^l04p^6 [Ar]4s^23d^l04p^4 Determine whether isopropyl alcohol evaporating form skin is exothermic or endothermic Exothermic Endothermic Define specific heat capacity. the quantity of heat required to raise the temperature of 1 mole of a substance by 1 degree C the quantity of heat required to change a system's temperature by 1 degree C the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree FExplanation / Answer
1. answer
kinetic energy
the vitality of a body or a framework as for the movement of the body or of the particles in the framework.
===============================
q2
calculate the change of internal energy for system that the giving off 622 kj heat and in performing 105 k j work
OPTION C = -727 KJ-ANSWER
=============================
q3
Ag
Silver has atomic number 47 occupying the ninth position in the 4d block.
s the electron configuration for silver is:[Kr] 4p105s1
Silver has one unpaired electron , hence it is paramagnetic
=================================================
delta U = delta H + delta W
delta U = -622 kj -105 k j= -727 KJ
===============================================================
q4
electronic configuration Br
[Ar] 3d10 4s2 4p5
========================================================
q5
Is the process of isopropyl alcohol evaporating from skin endothermic or exothermic?
answer = endothermic
isopropyl alcohol evaporating from skin by absorbing in heat from its surroundings to go from a liquid to a gas.
