A certain chemical reaction releases \( 26.0 \mathrm{~kJ} / \mathrm{g} \) of heat for each gram of reactant consumed. How can you calculate the heat produced by the consumption 3.7 kg of reactant? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. heat =

Quanti grammi di soluto bisogna aggiungere a \( 50,0 \mathrm{~g} \) di una soluzione al \( 10,0 \% \mathrm{~m} / \mathrm{m} \) perché la sua concentrazione raddoppi?

What is the hybridization of the central atom? \( s p \) \( s p^{2} \) \( s p^{3} d^{2} \) \( s p^{3} \) \( s p^{3} d \)

A metal is considered reactive if it easily loses electrons to achieve a stable octet. Would you prefer metal that readily loses electrons? How is this related to the metal's ionization energy? Would it be better for the metal to have high or low ionization energy?
