The correct option is A.
The chemical equation given above is an endothermic reaction. An endothermic reaction is a type of reaction which absorb heat from the environment. An endothermic reaction needs heat to occur, therefore, increasing the temperature of such a reaction will favor the formation of more product and the equilibrium of the reaction will shift [forward] to the right, which is the product side.
Answer:
A covalent bond
Explanation:
the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Answer:
The first row fits in period 2
The second row fits in period 3
Explanation:
Elements arranged vertically in the periodic table in groups that share similar chemical properties.
Elements are also organized horizontally in rows or periods
The length of each period is determined by the number of electrons that can occupy the sublevels being filled in that period.
