PSYCHO15rus [73]3 years ago
7 0

Answer:

Perchloric acid is one of the six common strong acids, which means 100% dissociation in water.  Thus, [HClO4] = [H+].

pH = -log 2.65 x 10^-5 = 4.58  

Explanation:

I am new, and I am giving this a try. Hope this helps : )

How can we increase the rate of collisions between the reactants in this reaction? mg 2hcl → mgcl2 h2
Minchanka [31]

<u>The frequency of </u><u>collisions </u><u>between the two reactants increases as the </u><u>concentration </u><u>of the reactants increases</u>. When collisions happen, they don't always cause a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations result in more collisions and reaction opportunities.

Increasing a reactant's surface area increases the frequency of collisions and thus the reaction rate. The surface area of several smaller particles is greater than that of a single large particle. The greater the available surface area for particles to collide, the faster the reaction will occur.

<h3>How does concentration affect the rate of collisions between reactants?</h3>

Thus, we can conclude that by increasing the concentration of Mg in the reaction mixture we increase the rate of collisions between the reactants in this reaction.

<h3>What does the half reaction of an oxidation-reduction reaction show?</h3>

Iron gains electrons in the half reaction of an oxidation-reduction reaction. What does iron's electron gain mean? It has been reduced. Predict the product that will precipitate out of the reaction using the solubility rules and the periodic table.

The carbon atoms in graphite and the carbon atoms in Diamond have different
Stolb23 [73]
It's the actual structure of diamond which made the two different. Diamonds have a tetrahedral structure, and as for graphite, it's not structured in that way. The structures of the two is also the reason why diamond is harder than graphite.
