Carbon dioxide could possibly be the answer unfortunately idk wat im talking about
Answer: aluminium, mercury , platinum and copper.
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
A general single displacement reaction can be represented as :
Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.
The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.
Answer:
John Dalton
Explanation:
John Dalton (1766-1844) is the scientist credited for proposing the atomic theory. This theory explains several concepts that are relevant in the observable world.
Answer:
The colliding molecules need to possess certain energy which is greater than the activation energy Ea and proper orientation.
<h3>Not all collisions result in a chemical reaction because not all collisions have the have sufficient amount of energy or have the appropriate activation energy. Nor do they all have this correct orientation. Molecules need to collide in such a way that they're oriented, so the correct bonds could break in. The correct bonds conform. And then, of course, they need to have sufficient activation energy in order to initiate the breaking of the bonds.</h3>
