ZnO
is the answer for what is the chemical formula for zinc?
Answer:
4
Explanation:
The equation for the reaction between bismuth(III) hypochlorite and acetic acid can be represented as:
Bi(ClO)₃ + 3CH₃COOH ------------------> Bi(CCH₃COO)₃ + 3 HClO
₃
Bi⁺³ + 3ClO⁻₃ + 3CH₃COO⁻ + 3H⁺-----------> Bi(CH₃COO)₃ + 3H⁺ + 3ClO
⁻₃
From the above reaction, we can therefore conclude that the free ions that are present at the product side of the total ionic concentration = 4.
Answer:
The question is not complete as it lacks the options. The options are;
A) i,ii, and iii
B) i and ii
C) i,iii,and iv
D) i,ii,iii, and iv
E) iii and iv
The answer is A.
Explanation:
A redox reaction i.e. oxidation-reduction is a reaction in which a change in the oxidation number or state of the participating atoms occur. A redox reaction, as the name implies, contains the oxidation part and the reduction part.
Just like any other reaction, redox reaction needs to be balanced as well. A balanced redox reaction must have the following characteristics:
- The same number of each type of atom on both sides of the equation. For example, if there are 4 atoms of Carbon on the reactant side, there must be 4 atoms of C on product side.
- The total number electrons lost in the oxidation equal to total number of electrons gained in the reduction. For example, if 12 electrons are gained in the reduction part, 12 electrons must be lost in the oxidation part.
- The same total charge of all ionic species on both sides of the reaction.
1) The time depends on what the lab wanted you to do. It will tell you in the procedure when you are supposed to considered a reaction to be complete and you just measure the time for that to happen.
2) Most text books say that increasing the concentration of one or more reactants will increase the rate of the reaction. To prove this with your data you need to show that when you increased the concentration of one of the reactants, the reaction rate did increase. The results of this experiment are not enough to make a general statement since the experiment was not on a large enough scale to diffidently prove anything. (you could have been testing the one exception or had a error in one of your trials)
I hope this helps. Let me know in the comments if anything is unclear.
(The concentration of one or more of the reactants will increase the rate of the reaction. This is explained through the fact that all reactions require collisions that have certain orientations and a minimum energy level. By increasing the concentration of one or more reactants, you increase the number of collisions which increases the rate since requires collisions in order to occur.) <span />
