Explanation:

The term IHD means index of hydrogen deficiency. It tells us the number of missing hydrogen atoms from a given chemical formula. This number of missing hydrogen atoms corresponds to the number and type of multiple bonds in a given compound.

The formula for IHD is; IHD = C + 1 + N/2 – H/2 – X/2

C = Number of carbon atoms

N = Number of nitrogen atoms

H = Number of hydrogen atoms

X = Number of halogen atoms

Since;

N=0, X=0

Then;

IHD = C + 1 – H/2

Hence;

IHD = 6 + 1 - 14/2

IHD = 7 -7

IHD = 0

An IHD of 0 implies that there is no hydrogen deficiency or multiple bond in the molecule. It is purely a saturated compound.

Explanation:

The radioactive dating is also called the radiometric dating. It involves the use of several radioactive substances like Argon, uranium, etc. The correct option is D.

The method of dating rocks and minerals using the radioactive isotopes is defined as the radioactive dating. This method is very helpful to determine the age of igneous and metamorphic rocks which cannot be measured using correlation method.

Many different radioactive isotopes and methods can be used for dating. The elements like uranium and potassium contain a number of different isotopes whose half life is known exactly and thus the concentration of these isotopes within a rock or mineral can measure the age.

The method radiocarbon dating is also used for determining the age of archaeological carbonaceous objects such as wood samples or animal fossils by measuring the radioactivity of ¹⁴C present in them.

Thus the correct option is D.

The question is incomplete, the complete question is;

The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula: =E−Ryn2 In this equation Ry stands for the Rydberg energy, and n stands for the principal quantum number of the orbital that holds the electron. (You can find the value of the Rydberg energy using the Data button on the ALEKS toolbar.) Calculate the wavelength of the line in the emission line spectrum of hydrogen caused by the transition of the electron from an orbital with =n10 to an orbital with =n8. Round your answer to 3 significant digits.

Answer:

162 * 10^-7 m

Explanation:

The Rydberg formula is;

1/λ= R(1/n2^2 - 1/n1^2)

R = Rydberg constant = 1.097 * 10^7 m-1

n2 = final state of the electron = 8

n1 = initial state of the electron = 10

Substituting values;

1/λ= 1.097 * 10^7(1/8^2 - 1/10^2)

1/λ= 1.097 * 10^7(1/64 - 1/100)

  1 / λ = 1.097 10⁷ (0.015625 - 0.01)

1 /λ = 0.006170625 10⁷

λ = (0.006170625 10⁷)^-1

λ = 162 * 10^-7 m

Answer:

Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other.

Answer:

That depends on the amount. Solubility is the maximum amount of salt dissolved in 100 g of water. So, if the amount is within limit, then yes. Solubility of anhydrous copper sulfate is 24.3 g/100 g water, so it is not bad. Put it in perspective, the solubility of NaCl is about 35 g/100 g water at room temperature. If the amount of copper sulfate is unknown, qualitative I'd say solid copper sulfate will dissolve in water completely.

Explanation:

If you use the pentahydrate CuSO4.5H2O then the solubility at 20°C is 20.8g/100ml H2O

If you use the anhydride, CuSO4. then the solubility at 20°C is 36.2g/100ml H2O

[tex]\boxed {\boxed {\sf 1.5935 \ mol \ FeCl_}}[/tex]

Explanation:

To convert from grams to moles, we must use the molar mass. This can be found on the Periodic Table. First, find the molar mass of iron and chlorine.

Check the formula. There is a subscript of 3 after Cl, so there are 3 atoms of chlorine in 1 molecule. Multiply iron's molar mass by 3, then add iron's molar mass.

Use this number as a ratio.

[tex]\frac {162.19 \ g\ FeCl_3}{1 \ mol \ FeCl_3}[/tex]

Multiply by the given number of grams.

[tex]258.45 \ g \ FeCl_3 *\frac {162.19 \ g\ FeCl_3}{1 \ mol \ FeCl_3}[/tex]

Flip the ratio so the grams of iron (III) chloride cancel.

[tex]258.45 \ g \ FeCl_3 *\frac {1 \ mol \ FeCl_3}{162.19 \ g\ FeCl_3}[/tex]

[tex]258.45 *\frac {1 \ mol \ FeCl_3}{162.19}[/tex]

[tex]\frac {258.45 \ mol \ FeCl_3}{162.19}[/tex]

[tex]1.59350144892 \ mol \ FeCl_3[/tex]

The original measurement of grams has 5 significant figures, so our answer must have the same. For the number we calculated, that is the ten thousandth place.

[tex]1.5935 \ mol \ FeCl_3[/tex]

258.45 grams is approximately 1.5935 moles of iron (III) chloride.

Explanation:

If we look at the tests to be performed on the compounds carefully, we will notice that;

i) Addition of H2S with 0.2 M HCl produced a black solid. This black solid may result from the reaction;

H2S + Cu2+ ---->CuS(balck solid) + H2

or

H2S + Pb2+  ---->PbS(balck solid) + H2

Hence, Cu2+ or Pb2+  may be present

ii) Addition of (NH4)2S produced a white solid. This means that  K^+ may be present because the white precipitate is formed during metathesis.

iii) Potassium ion is known to burn with a purple flame.

Hence the suspected ions are;

Cu2+ , Pb2+ and  K^+

Answer: Your balanced equation is 2Al + 3S --> Al_2S_3. In two separate equations, first use the 48.5g of Al to find the amount (in moles) of Al_2S_3. Then use the 62.8g of S to find the amount (in moles) of Al_2S_3. By doing these, you find which reactant (the Al or the S) produces the least amount of Al_2S_3. Since it's the S, that's the limiting reactant: you then use that 62.8g of S to find how many grams of Al will be used in the reaction. (Use the same balanced equation.) You find that 35.2g of Al will be used, then find the excess by subtracting that 35.19 from the original 48.5g. Your excess amount is 13.3g of Al!

Explanation:

hopefully this is what you were looking for <3 :)

The amount of excess reactant that left over the chemical reaction between aluminum and ammonium perchlorate is 0.9 moles.

Mass into moles (n) will be converted by using the below equation as:

n = W/M, where

W = given mass

M = molar mass

Moles of 45g of Aluminum = 45g / 27g/mol = 1.66 mol

Moles of 301g of ammonium perchlorate = 301g / 117.4g/mol = 2.56 mol

Both reactants are reacted with each other and one of the reactant is fully consumed, so the excess reactant will be calculated as:

Excess reactant = 2.56mol - 1.66mol = 0.9 moles

Hence amount of excess reactant is 0.9 moles.

Answer:

The correct answer is - 2CO2 or two molecules of carbon dioxide.

Explanation:

The TCA cycle or citric acid cycle is a central pathway of cellular respiration that helps in unifying several metabolites and generates energy for cellular functions. It takes place over eight different steps:

Step 1:  Acetyl CoA enters the citric acid cycle that is a 2-carbon compound and attaches with 4-carbon compound oxaloacetate to form citrate a 6 carbon compound

Step 2: This 6-carbon compound isocitrate

Step 3: 5 carbon compound alpha-ketoglutarate is produced by oxidizing the isocitrate and release the release of carbon dioxide. One NADH molecule is formed.

Step 4: This 5 carbon molecule is oxidized again to form a four-carbon compound that binds with CoA to make forming succinyl CoA. A second molecule of NADH is produced, alongside a second molecule of carbon dioxide.

Step 5: Succinyl CoA is then converted to succinate with GTP formation

Step 6: Succinate is converted into fumarate with the generation of FADH₂ molecule.

Step 7: Fumarate is converted to malate

Step 8: oxaloacetate is formed with the NADH molecule.
