Answer:
The ΔH° for the following reaction is -794 kJ, hence exothermic reaction,
Explanation:
ΔH° = ?
We are given with:
ΔH° =
(Energies required to break bonds on reactant side) - (Energies released on formation of bonds on product side)
endothermic reaction
exothermic reaction
The ΔH° for the following reaction is -794 kJ, hence exothermic reaction,
Metalloids are all solid at room temperature<span>. Some metalloids, such as silicon and germanium, can act as </span>electrical<span> conductors under the right conditions, thus they are called semiconductors. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is brittle - a characteristic of some nonmetals).

Answer:
1. ions
2. ions
Explanation:
Metals lose electrons and form positive ions (because there are more protons+)
While non-metals gain electrons and form negative ions.(more electrons-)
