Because the penny absorbs the kinetic energy from the impact and releases it back into the environment as heat since the energy cannot be stored as potential energy.
Answer: d-orbitals account for the sulphur- oxygen double bond.
Explanation:
Looking at the nature of bonding in SOCl2, the sulphur is bonded to two chlorine atoms and one oxygen atom. The sulphur has a lone pair of electrons. There are four bonds and four electron pairs if we don't count the lone pair on sulphur. This leads to a tetrahedral shape. However, if we invoke a valence state in which d orbitals are involved and the thionyl chloride is still sp3 hybridized, then we will have one electron in the d-orbital which overlaps with a 2p electron from oxygen to form the double bond. The four sp3 orbitals accommodate eight electrons including the lone pair on sulphur while the d-orbital accommodates the remaining two electrons from the pi-bond thereby completing the ten electrons.

The final temperature of the water will be 31.2 °C... i don’t know the second one sorry :(
The processes that experience energy loss included the following: FREEZING, CONDENSATION AND DEPOSITION.
Energy loss occurs in these processes because the kinetic energy of the particles decreases as a result of the change in state that they undergo. For instance, for the process of freezing, a substance has to change from the liquid state to the solid state. The amount of kinetic energy that is available to the particles of the liquid is more than that of the solid, thus, the particles are losing some kinetic energy.
The processes that experience energy gains are: SUBLIMATION, EVAPORATION AND MELTING. These processes move from a state of lower kinetic energy to that of higher kinetic energy.
Empirical formula is the simplified version of molecular formula.
