Answer:
1 ans =The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.
Answer:
quantity of heat=mc*theta
=25*0.930(76-25)
=25*0.930*51
=1185.75J
=11.9kJ

Explanation:
Answer:
Becuase CH30 has weaker inter-molecular forces
Explanation:
Becuase its intermolecular forces are weaker the particals will seperate more easilyl.
Answer:
Because the total energy of the enzyme has been used up and actions already complete
Explanation:
Catalyst are substance known to speed up rate of chemical reaction just like taking a short pathway. When velocity of catalyzed reaction reach maximum, at that moment reaction has reach it full potential (there is an equilibrium in reaction). there won't be any changes on further addition, and mostly indicate that Reaction is Complete
