What is the final temperature when a 348.00g block of ice at -44.5°C is added to 95.00 g of steam at 125.5°C in an insulated system? Assume the final result will be liquid water.

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.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

a polar bond is formed when electrons are shared unevenly between atoms
