Answer:
B - The energy of reactants is conserved.
D - the nuclei of atoms changes completely ( if that's the option)
Chemistry is very important to study. Chemistry explains the natural world around us and also explains certain chemical processes that happen here on earth.
The heat from your hand would be absorbed by the (assumed) colder flask, since an endothermic reaction means that the reaction requires an absorption of heat as opposed to an exothermic reaction, which releases heat.
CH₄ is a non-polar molecule, which means that it will contain only Van der Waals forces and induced dipole-dipole forces. These forces are weak, which is evident in the fact that methane is a gas at room temperature.
H₂O is a polar molecule, with hydrogen bonded to an electronegative atom, oxygen. This means that the forces present between water molecules are hydrogen bonding and dipole forces. These forces are comparatively strong, which results in water's liquid state at room temperature.
CO has dipole forces, which arise due to the difference in electronegativity between carbon and oxygen.
Chloromethane also possesses dipole forces for the same reason as CO does.
