2Al + 6HCl ----> 2AlCl3 + 3H2
Chemically bonded together
Answer:
is used to break reactant bonds and/or make new product bonds.
Explanation:
<em>The correct answer would be that </em><em>activation energy is used to break reactant bonds and/or make new product bonds</em><em>.</em>
The <u>activation energy is the minimum energy that must be overcome by the reactants in a reaction in other to become products</u>. In order for products to be formed, the bonds between reactants must be broken and new ones must be formed to arrive at the products. In other words, the activation energy can be seen as the energy required to break the bonds between reactants and form the bonds between products during the course of a reaction.
<em>Activation energy is required even in the presence of enzymes. The latter only catalyzes reactions by lowering the minimum energy required to break the bonds between reactants and form new ones between products</em>.
Greenhouse gases are the gases in the atmosphere that keep the air in the atmosphere. It also traps the sun's sunlight. Since the heat is trapped in here, it would contribute to higher temperatures. *Have a nice day!!*
