Answer:
H⁺(aq)
Explanation:
Let's consider the following redox reaction.
Sn(s) + 2 H⁺(aq) → Sn²⁺(aq) + H₂(g)
We can identify both half-reactions.
Oxidation: Sn(s) → Sn²⁺(aq) + 2 e⁻
Reduction: 2 H⁺(aq) + 2 e⁻ → H₂(g)
Sn(s) undergoes oxidation so it is the reducing agent, while H⁺(aq) undergoes reduction so it is the oxidizing agent.
Answer:
An aldehyde is a carbonyl group with a carbonyl carbon bonded to hydrogen and can be oxidized to a ketone while a ketone is a carbonyl group with a carbonyl carbon only bonded to oxygen atom and cannot be oxidized
Some of oxidizing agents are potassium dichromates, bradys reagent....
Answer:
1) compaction and cementation
2) Gneiss
3)crust
Explanation:
Firstly need to determine the empirical formula of the hydrocarbon. Empirical formula is the simplest whole number ratio of components of the compound. Molecular formula is the actual composition of the components in the compound.
percentage of C - 82.66%
percentage of H - (100-82.66) = 17.34 %
in 100 g of compound ;
mass of C - 82.66 g
mass of H - 17.34 g
C H
mass in 100 g 82.66 g 17.34 g
molar mass 12 g/mol 1 g/mol
number of moles 6.88 mol 17.34 mol
(mass/molar mass)
divide the number of moles by least number of moles (6.88 mol)
6.88 mol/6.88 17.34/6.88
1 2.52
multiply these by 2 to get a whole number
C - 1x 2 = 2
H - 2.52 x 2 = 5.04
round off to nearest whole number
C - 2
H - 5
ratio of C to H is 2:5
empirical formula - C₂H₅
empirical formula mass = 12 g/mol x 2 + 5 * 1 g/mol = 29 g
next have to find how many empirical units are there in the molecular unit
molecular unit mass = 58.12 g
empirical unit = 29 g
then number of empirical units = 58.12 / 29 = 2
rounded off , number of empirical units = 2
(C₂H₅) * 2 units
molecular formula = C₄H₁₀
Explanation:
Alicia took half of her salary which is $42.15. So the total amount of her salary is $84..30.
Therefore, x-$42.15 ≥ $20.00
$84.30/x ≥$62.15
