Answer:

3-ethyl-1-hexyne or 4-ethyl-1-hexyne.

Explanation:

Hello,

By means of the more likely reagents to undergo the stated hydrogentation via catalysis with palladium or platinum, its structure is shown on the attached picture which is eligible for either 3-ethyl-1-hexyne or 4-ethyl-1-hexyne since they lead to the very same product. Do not forget that such hydrogenation covers up all the insaturations turning out into the specified alkane.

Best regards.

List the number of each type of atom on the left side of the equation 2C10H22(l)+31O2(g)→20CO2(g)+22H2O(g)
ValentinkaMS [17]

Answer: There are 20 carbons atoms, 62 oxygen atoms and 44 carbon atoms on the left side of the equation.

Explanation:

In the given chemical reaction:

2C_{10}H_{22}(l)+31O_2(g)\rightarrow 20CO_2(g)+22H_2O(g)

Reactants side = Left side

Number of atoms =

Coefficient × Number of atoms of an element in a unit molecular formula

Number of carbon atoms = 2 × 10 = 20

Number of oxygen atoms = 31 × 2 = 62

Number of hydrogen atoms =  2 × 22 = 44

Write a balanced half-reaction for the oxidation of liquid water H2O to aqueous hydrogen peroxide H2O2 in basic aqueous solution
nignag [31]

Answer : The balanced half-reaction in a basic solution will be,

2OH^-(aq)\rightarrow H_2O_2(aq)+2e^-  

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Rules for the balanced chemical equation in basic solution are :

First we have to write into the two half-reactions.

Now balance the main atoms in the reaction.

Now balance the hydrogen and oxygen atoms on both the sides of the reaction.

If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.

If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion (OH^-) at that side where the less number of hydrogen are present.

Now balance the charge.

  • The half reaction is :

H_2O(l)\rightarrow H_2O_2(aq)

  • Now balance the oxygen atoms.

H_2O(l)\rightarrow H_2O_2(aq)+H_2O(l)

  • Now balance the hydrogen atoms.

H_2O(l)+2OH^-(aq)\rightarrow H_2O_2(aq)+H_2O(l)

  • Now balance the charge.

H_2O(l)+2OH^-(aq)\rightarrow H_2O_2(aq)+H_2O(l)+2e^-

The balanced half-reaction in a basic solution will be,

2OH^-(aq)\rightarrow H_2O_2(aq)+2e^-

You prepare a standard by weighing 10.751 mg of compound X into a 100 mL volumetric flask and making to volume. You further dilu
ArbitrLikvidat [17]

Answer:

0.12693 mg/L

Explanation:

First we <u>calculate the concentration of compound X in the standard prior to dilution</u>:

  • 10.751 mg / 100 mL = 0.10751 mg/mL

Then we <u>calculate the concentration of compound X in the standard after dilution</u>:

  • 0.10751 mg/mL * 5 mL / 25 mL = 0.021502 mg/L

Now we calculate the<u> concentration of compound X in the sample</u>, using the <em>known concentration of standard and the given areas</em>:

  • 2582 * 0.021502 mg/L ÷ 4374 = 0.012693 mg/L

Finally we <u>calculate the concentration of X in the sample prior to dilution</u>:

  • 0.012693 mg/L * 50 mL / 5 mL = 0.12693 mg/L

Determine the mass in grams of 125 mol of neon
Vesnalui [34]
Molar mass of Neon ( Ne ) = 20.1797 g/mol

m = n * mm

m = 125 * 20.1797

m = 2522.4625 g

hope this helps!
