Neither Compound A nor Compound B is aromatic.

The statement "compound A is a 3 carbon ring with a double bond between carbons 1 and 2. carbon 3 has a lone pair and a negative charge and is bonded to one hydrogen" and "compound b is a 5 carbon ring with two double bonds. the non-alkene carbon has a carbocation" is true.

Compound A is not considered to be aromatic because it does not meet the criteria for aromatic compounds. Aromatic compounds have a specific type of cyclic and fully conjugated system of electrons which allows them to have delocalized pi electrons and a cyclic ring of alternating single and double bonds. Compound A has a three-carbon ring with a double bond between carbons 1 and 2, but the third carbon has a lone pair and a negative charge, which breaks the conjugation of the ring.

It also lacks the cyclic ring of alternating single and double bonds, which is a requirement for aromaticity.

Compound B is not considered to be aromatic because it does not meet the criteria for aromatic compounds. Aromatic compounds have a cyclic ring of alternating single and double bonds.

If we have 325 grams of glucose and 137 grams of oxygen, the limiting reagent is oxygen. The mass of carbon dioxide that will be produced is 137 grams.

This means that the reaction will be limited by the amount of oxygen available, and not by the amount of glucose. The mass of carbon dioxide that will be produced will be equal to the mass of oxygen used in the reaction. In this case, 137 grams of carbon dioxide will be produced.

The reaction can be written as: glucose + oxygen --> carbon dioxide + water. This equation shows that for every molecule of glucose, 6 molecules of oxygen are needed to produce 6 molecules of carbon dioxide and 6 molecules of water.

Therefore, the amount of carbon dioxide produced will depend on how much oxygen is available. In this case, 137 grams of oxygen is available, so 137 grams of carbon dioxide will be produced.

If the natural abundance of chlorine-35 is 75.8% and that of chlorine-37 is 24.2%, then the average atomic mass of chlorine will be 35.44 amu.

Chlorine exists in two isomeric forms which are the chlorine-35 and chlorine-37. The atomic mass of the chlorine elements is basically the average atomic mass of its isotopes depending upon their abundance in nature.

The atomic mass of chlorine-35 is 34.97amu and a natural abundance equal to 75.8 %. The atomic mass of chlorine-37 is equal to 36.97 amu with an abundance of 24.2%.

To calculate the average atomic mass of chlorine,

The amount of heat needed to boil 15.5 g of methanol (ch3oh). the molar heat of vaporization for methanol is 35.21 kj/mol. the molar mass of methanol is 32.04 g/mol.

To calculate the amount of heat needed to boil 15.5 g of methanol, we need to use the formula: Q = mL

Where Q is the heat energy, m is the mass of the substance, and L is the molar heat of vaporization.

First we need to find the moles of methanol:

moles = mass / molar mass

moles = 15.5 g / 32.04 g/mol = 0.4828 moles

Then we can calculate the heat energy required to boil the methanol:

Q = mL

Q = 0.4828 moles * 35.21 kJ/mol

Q = 17.04 kJ

Explanation:

Dipole-dipole interactions are a type of chemical bonding that occurs between two polar molecules. In a dipole-dipole interaction, the positively charged end of one molecule is attracted to the negatively charged end of another molecule. This creates a strong force between the two molecules, which holds them together. Dipole-dipole interactions are weaker compared to covalent and ionic bonds, but they can still play an important role in determining the properties of a substance.

First work out the moles of NaOH dispensed from the burette:

Next use the balanced equation to reason how many moles of HCl are present in the flask:

2. 1:1 therefore 0.00250 moles NaOH

Explanation:

Answer:

The concentration of the hydrochloric acid is 0.00047 mol/dm³.

Explanation:

The balanced equation for the reaction is:

2 HCl(aq) + Ba(OH)2(aq) → BaCl₂(aq) + 2H₂O

We know that 25.00 cm³ of the hydrochloric acid reacted with 23.50 cm³ of the 0.100 mol/dm³ barium hydroxide solution.

Given the balanced equation, it is clear that 2 moles of hydrochloric acid react with 1 mole of barium hydroxide. As we know the volume and concentration of the barium hydroxide, we can calculate the number of moles of barium hydroxide present in the 23.50 cm³ of solution.

23.50 cm³ of 0.100 mol/dm³ barium hydroxide = (23.50 x 0.100) / 1000 = 0.00235 moles

As 2 moles of hydrochloric acid react with 1 mole of barium hydroxide, and we know the number of moles of barium hydroxide, we can calculate the number of moles of hydrochloric acid.

0.00235 moles of barium hydroxide / 2 = 0.001175 moles hydrochloric acid

We have the number of moles of hydrochloric acid, we can calculate the concentration in mol/dm³.

0.001175 moles hydrochloric acid / 25.00 cm³ = 0.00047 mol/dm³

The concentration of the hydrochloric acid is 0.00047 mol/dm³.

A 64.8 g 64.8 g sample of the compound x2o5 x 2 o 5 contains 48.0 g 48.0 g of oxygen atoms. The molar mass of element x is 56 g/mol.

To determine the molar mass of element X, we can use the information provided about the mass of the compound and the mass of the oxygen atoms.

First, convert the mass of the compound to moles by dividing it by the molar mass of the compound:

(64.8 g) / (molar mass of X2O5) = moles of X2O5

Next, use the moles of X2O5 to determine the moles of oxygen atoms by multiplying by the number of oxygen atoms per molecule of X2O5:

moles of X2O5 x (5 moles of O / 1 mole of X2O5) = moles of O

Then, convert the mass of the oxygen atoms to moles by dividing it by the molar mass of oxygen:

(48.0 g) / (16.00 g/mol) = 3.00 moles of O

We know that the mass of the compound is equal to the mass of the element X and the mass of the oxygen atoms.

mass of X = mass of the compound - mass of the oxygen atoms

mass of X = 64.8 - 48.0 = 16.8 g

convert the mass of element X to moles by dividing it by the molar mass of X:

(16.8 g) / (molar mass of X) = moles of X

Now we can calculate the molar mass of element X by using the moles of X and the mass of X

molar mass of X = mass of X / moles of X

molar mass of X = 16.8 g / (3.00 moles of O x (1 mole of X2O5 / 2 moles of X)) = 56 g/mol.

The molar mass of element X is 56 g/mol.

Answer:

Explanation:

For every 2 moles of H3PO4 that is reacted, 6 moles of H2O are produced.

So if 5.2 moles of H3PO4 are reacted with calcium hydroxide, calculate the moles of H2O produced by this:

5.2 moles H3PO4 * (6 moles H2O / 2 mole H3PO4) = 15.6 moles H2O

Therefore 15.6 moles of H2O would be produced if 5.2 moles of H3PO4 are reacted with calcium hydroxide.

The volume of the metal sample is 6.2 ml

The theory behind this is that the volume of the metal is what causes the increase in water volume in the cylinder.

This means that by comparing the volume occupied by the water and metal together and the amount occupied by the water alone in the cylinder, you can determine the volume of the metal.

To be more specific, the volume of the metal will be,

Vmetal= Vwater + metal - Vwater

In this case, we have

Vwater = 23.6 ml

Vwater + metal = 29.8 ml

So,

Vmetal = 29.8 ml - 23.6 ml = 6.2 ml

If 19.4 grams of ammonium chloride are used, option D (10.63 g) of water are theoretically produced.

The balanced equation for the reaction between ammonium chloride and water is:

NH4Cl + H2O ---> NH3 + HCl

From the balanced equation, we can see that for every 1 mole of NH4Cl, 1 mole of H2O is produced.

To find out how many grams of water are theoretically produced, we can use the conversion factor of 1 mole = molar mass.

The molar mass of NH4Cl is (114.01 + 41.01) = 18.05 g/mol

19.4 g of NH4Cl is equal to 19.4/18.05 = 1.07 mol

So, theoretically 1.07 mol of H2O is produced, which is equal to the molar mass of H2O (18.02 g/mol) x 1.07 mol = 19.37 grams of water.

So, the answer is 19.37g of water.
