Answer: The correct answer is Francium and Fluorine.
Explanation:
The most vigorous chemical reaction will occur between the most reactive metal and most reactive non-metal.
Reactivity of metal is defined as the tendency of elements to loosing electrons easily. Reactivity of metals decreases as we move from left to right and increases as we move down in the group. Hence, the most reactive metal is Francium.
Reactivity of non-metals is defined as the tendency of the element to gain electrons easily. Reactivity of non-metals increases across a period and decreases as we move down in a group. Hence, the most reactive non-metal is Fluorine.
Therefore, the most vigorous chemical reaction will occur between Francium and Fluorine.
Answer:
group 2
Explanation:
because they are the only alkalines earth metals on the periodic table
Answer:
Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well. Natural resources are used to make food, fuel and raw materials for the production of goods.
Answer:
Explanation:
2 NO2(g) ⇄ N2O4(g)
Adding Argon to this reaction will have NO effect. Catalysts nor inert gases have an affect on equilibrium conditions.
Only changes in concentration, temperature conditions and pressure-volume conditions (unless both sides have equal molar volumes) will affect the equilibria.
NH4OH(aq) ⇄ NH3(g) + H2O(l)
Removing ammonia from reaction equilibrium causes the reaction to shift right to replace removed ammonia. => Think of the reaction as being on a seesaw => removing ammonia from the product side tilts the seesaw left causing the NH₄OH to decompose and deliver more NH₃ and H₂O to the product side to increase weight on that side and level the seesaw. :-)
C.) Ionic bond is formed between that...
