For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in mL. The solution is as follows:
14.5 mg * 1 mL/25 mg = 0.58 mL
Answer:
rate: K' [H₂O₂]
Explanation:
Every chemical reaction occurs with a determined mechanism. The slow step of the reaction is the rate determining.
According to the reaction:
H₂O₂(aq) → 2 H₂O(l) + O₂(g)
The proposed mechanism (And its rate laws) in the presence of I⁻ is:
Step 1: H₂O₂ + I⁻ → H₂O + OI⁻ (slow) rate₁: K₁ [H₂O₂] [I⁻]
Step 2: H₂O₂ + OI⁻ → H₂O + O₂ (fast) rate₂: K₂ [H₂O₂] [OI⁻]
As the step 1, is the rate-determining, the rate law for the overall reaction is:
<em>rate: K [H₂O₂] [I⁻]</em>
Now, as I⁻ is a catalyst and its concentration over the reaction is constant, it is possible to write:
<em>rate: K' [H₂O₂]</em>
<em>Where K' = K [I⁻]</em>
Answer:
We'll produce 10 moles of H2O if 5 moles of O2 are used
Explanation:
Step 1: Data given
Number of moles oxygen = 5.0 moles
Step 2: The balanced equation
2H2 + O2 → 2H2O
Step 3: Calculate number of moles of H2O produced
For 2 moles H2 we need 1 mol O2 to produce 2 moles H2O
For 5.0 moles O2 we'll need 2*5 = 10 moles H2 to produce 2*5 = 10 moles H2O
We'll produce 10 moles of H2O if 5 moles of O2 are used
Answer:
i don't think anyone is going to be able to answer every single one of those

In acidic solition, the coefficient of permanganate ion in the balanced redox equation is 2.
<h3>How can a redox equation be balanced?</h3>
A redox equation showing a reduction and an oxidation reaction occurring simultaneously.
To balance redox equations, the atoms reacting as well as the electrons transferred are balanced.
In the reaction of permanganate ion and bromide ion in acidic solution, the balanced redox equation is given as follows:
- 2 MnO4- + 10Br- + 16 H+ → 2 Mn2+ 5 Br2 + 8 H2O
Therefore, the coefficient of permanganate ion in the balanced redox equation is 2.
