Balance the following redox reaction if it occurs in acidic solution. What are the coefficients in front of h2c2o4 and h2o in the balanced reaction? mno4⁻(aq) h2c2o4(aq) → mn2 (aq) co2(g)
Answers
The balanced redox reaction, if it occurs in acidic solution, is
5C₂O₄²⁻(aq) + 2MnO₄⁻(aq) + 16H⁺-----> 10CO₂(g) + 2Mn²⁺(aq) + 8H₂O(l)
What are redox reaction?Redox reactions are those in which loss and again of electrons occur.
To balance the redox reaction, we must first break the whole reaction into half equations;
Oxidation half equation
[tex]\rm 5C_2O4^2^-(aq) + 10e + 8H^+----- > 10CO_2(g) + 4H_2O(l)[/tex]
Reduction half equation
[tex]\rm 2MnO_4^- (aq) + 10e + 8H^+----- > 2Mn^2+(aq) + 4H_2O(l)[/tex]
Now combine both the reactions
[tex]\rm 5C_2O_4^2-(aq) + 2MnO4^- (aq) + 16H^+----- > 10CO_2(g) + 2Mn^2+(aq) + 8H_2O(l)[/tex]
Thus, the coefficient of H₂C₂O₄ is 5 and that of water is 8.

In a certain reaction at stp, 29.2 l of methane is combusted
with 63.3 l of oxygen.
what volume of excess reactant remains after the reaction is
complete?
Answers
The volume of excess oxygen will 2.28 L
Stoichiometric calculationFrom the equation of the reaction:
[tex]CH_4(g) + 2O_2(g) --- > CO_2(g) + 2H_2O(g)[/tex]
The mole ratio of the two reactants is 1:2.
1 mole of gas at STP = 22.4 L
Mole of 29.2 L of methane at STP = 29.2/22.4 = 1.3 moles
Mole of 63.3 L of oxygen at STP = 63.3/22.4 = 2.8 moles.
Thus, oxygen is in excess because 1.3 x 2 = 2.6 moles is needed to react with 1.3 moles methane.
Excess mole of oxygen = 2.8 - 2.6 = 0.2 moles
Volume of 0.2 moles at STP = 22.4 x 0.2 = 2.28 L

Explanation:
1/2 ^n = .15 (.15 is 15% in decimal)
log both sides
n log (1/2) = log (.15 )
n = 2.737 half lives
EACH half life is 100 million

how can you explain that even though you continue to add pure water into a substance, even though the resultant ph might differ a little, the acidity or alkalinity of substance still remains the same to that of substance?
Answers
Addition of pure water does not change pH of a solution because pure water has neutral pH.
Why the pH does not change when pure water is added?Even though you continue to add pure water into a substance, the acidity or alkalinity of substance still remains the same to that of substance because pure water has neutral pH which can't change the acidity or alkalinity of a solution.
So we can conclude that addition of pure water does not change pH of a solution because pure water has neutral pH.

What is a reversible reaction?A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.
Conditions for reversible reactionIn equilibrium reaction, the activation energy of the forward reaction is more than that of backward reaction which causes bond breakage of the reactants.
Activation energy = (Threshold energy) - (Internal energy of the reactants)

Strontium bromide contains only strontium and bromine. What is the formula for this compound?.
Answers
[tex]SrBr_{2}[/tex]
Explanation:Chemical formulas are a way to show the elements and the amount of each element present in a compound.
Element Symbol
To write a chemical formula you need to use their chemical symbols. So, we need to find the symbols for strontium and bromide.
Strontium is SrBromine is BrCharges
However, elements do not combine in random ratios. The ratios are based on charges so that all compounds have a neutral charge. Elements will have different subscripts to ensure that compounds have a neutral overall charge. So, to correctly write the formula we need to know the charges Sr and Br have when they became ions.
Sr gains a charge of +2Br gains a charge of -1To cancel the positive 2 out, we must have 2 bromines. That means the final formula for strontium bromide is [tex]SrBr_{2}[/tex]. Now, the compound has a charge of 0.

Balance the following chemical reaction :p(s) + cl2(g) = pcl5(s)
Answers
Answer:
[tex]2\text{P}+ 5\text{Cl}_2 \rightarrow 2\text{PCl}_5[/tex]
Explanation:
Answer:
2P (s) + 5PCl₂ (g) → 2PCl₅ (s)
Explanation:
There are 2 chlorine atoms on the reactant side and 5 chlorine atoms on the product side.
Hence, multiply the left chlorine molecule by 5 and right compound by 2.
⇒ P (s) + 5 × Cl₂ (g) → 2 × PCl₅
⇒ P (s) + 5Cl₂ (g) → 2PCl₅ (s)
But, now we see that there is 1 phosphorus atom on the reactant side and 2 phosphorus atoms on the right.
So, multiply the left phosphorus atom by 2 to balance.
⇒ 2 × P (s) + 5PCl₂ (g) → 2PCl₅ (s)
⇒ 2P (s) + 5PCl₂ (g) → 2PCl₅ (s)

The conductance of the electric current through the electrolytic solution increases with increase in concentration.
What is an electrolytic solution?An electrolytic solution is a solution containing dissolved electrolyte.
The ions of the electrolyte dissociate and are able to carry electric current around the electrolytic cell.
The higher the concentration of the electrolyte, the more electric current it can conduct due to greater number of ions present.
Therefore, the conductance of the electric current through the electrolytic solution increases with increase in concentration.
