Aluminum is a metal and reacts violently with all halogen elements, including bromine. ... As can be observed from the reaction enthalpy, the reaction is highly exothermic and a large amount of energy is released during the aluminum(III) bromide synthesis.
These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
All rocks on Earth take part in the "Rock Cycle". For an igneous or metamorphic rock to change into a sedimentary rock, they must undergo weathering and erosion by wind, water, and/or ice. The broken down pieces of rock (sediments) settle into layers that form a sedimentary rock.
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.
