Answer:

\(210.7~g~MgCO_3\)

Explanation:

We have to start with the reaction:

\(MgCO_3~->~MgO~+~CO_2\)

We have the same amount of atoms on both sides, so, we can continue. The next step is to find the number of moles that we have in the 110.0 g of carbon dioxide, to this, we have to know the atomic mass of each atom:

C: 12 g/mol

O: 16 g/mol

Mg: 23.3 g/mol

If we take into account the number of atoms in the formula, we can calculate the molar mass of carbon dioxide:

\((12*1)+(16*2)=44~g/mol\)

In other words: \(1~mol~CO_2=~44~g~CO_2\). With this in mind, we can calculate the moles:

\(110~g~CO_2\frac{1~mol~CO_2}{44~g~CO_2}=25~mol~CO_2\)

Now, the molar ratio between carbon dioxide and magnesium carbonate is 1:1, so:

\(2.5~mol~CO_2=2.5~mol~MgCO_3\)

With the molar mass of \(MgCO_3\) (\((23.3*1)+(12*1)+(16*3)=84.3~g/mol\). With this in mind, we can calculate the grams of magnesium carbonate:

\(2.5~mol~MgCO_3\frac{84.3~g~MgCO_3}{1~mol~MgCO_3}=210.7~g~MgCO_3\)

I hope it helps!

Explanation:

The acid commonly used to acidify KMnO4  is H2SO4. The reason why HNO3  is not used is because HNO3  is itself a strong oxidizing agent. HCl is not used because it can react with KMnO4.

FeSO4 solution is usually prepared fresh when needed because if the solution is prepared and left to stand for sometime, FeSO4  is oxidized to Fe2(SO4)3 by air. Fe III does not give the brown ring test.

Alkali are not stored in glass stopped reagent bottles because very strong alkali can cause the stopper to corrode and fuse to the neck of the bottle making it very difficult to open the reagent bottle.

The expected temperature change would be approximately 4.32°F if 0.5-gram sample of water released 0.0501 j of heat energy.

The specific heat of a substance is the amount of heat energy required to raise the temperature of one gram of the substance by one degree Celsius. The expected temperature change can be calculated using the formula:

q = m × c × ΔT

where q is the heat energy released, m is the mass of water, c is the specific heat of water, and ΔT is the change in temperature.

Rearranging the formula to solve for ΔT, we get:

ΔT = q ÷ (m × c)

Substituting the given values, we get:

ΔT = 0.0501 J ÷ (0.5 g × 4.184 J/g°C)

ΔT ≈ 2.4°C or 4.32°F

When a substance undergoes a change in temperature, it either gains or loses heat energy.

At pOH value  of 6.0 the pH value of the following solution is 8.0 and the concentration of [\(H^{+}\) ] ion is \(10^{-8}\)

In this question we will apply the formula

      pH +pOH = 14 . . . . . . . . . . . . .(1)

where pH = concentration of [\(H^{+}\) ] ion

pOH = concentration of [\(OH^{-}\) ] ion

As per the question

pOH =6.0

Putting the value of pOH in equation (1) we get the value of pH

              pH + 6.0 =14

             pH = 14 -6.0

             pH  = 8.0

 The value of pH if the pOH value is 6.0 is 8.0

To find the concentration of \(H^{+}\) ion we will use the following formula

This is calculated by the formula

                                 [\(H^{+}\)} = \(10^{-pH}\)

where we will write the values of pH

Hence the concentration of [\(H^{+}\)} ion is \(10^{-8}\)

Therefore at  pOH of 6.0 the pH value of the following solution is 8.0 and the concentration of [\(H^{+}\) ] ion is \(10^{-8}\)

Answer:

A) Using the ideal gas law, we can calculate the number of moles of gas present:

```

PV = nRT

```

where:

* P = pressure (atm) = 1 atm

* V = volume (L) = 5.6 L

* n = number of moles of gas

* R = ideal gas constant = 0.08206 L atm / mol K

* T = temperature (K) = 273.15 K

Solving for n, we get:

```

n = (P * V) / RT

```

```

n = (1 atm * 5.6 L) / (0.08206 L atm / mol K * 273.15 K)

```

```

n = 0.25 mol

```

Therefore, there are 0.25 moles of gas present.

B) The molar mass of the gas can be calculated by dividing the mass of the gas (8.0 g) by the number of moles of gas (0.25 mol):

```

Molar mass = Mass / n

```

```

Molar mass = 8.0 g / 0.25 mol

```

```

Molar mass = 32 g/mol

```

The molar mass of the gas is 32 g/mol.

C) The common atmospheric gas with a molar mass of 32 g/mol is oxygen (O2). Therefore, the gas that was collected is oxygen.

The appropriate diagram of the question is shown in the first image attached below.

From the diagram, we see the reaction of Cyclopentanol taking place under Tscl pyridine. We are to show the reaction mechanism and determine from the options, which appropriate product fits in.

So, from the reaction, the hydroxyl substituent reacts with Tscl where cl is being lost. This process is followed by an attack of N substituent on the pyridine with the Hydrogen atom and cleaves off for the structure to form a stable structure. The stereochemistry of the compound remains unchanged and it maintains its stick formula.

Thus, X is the appropriate and the correct product.

Answer:

4P+ 3(O2)= 2(P2O3)

Explanation:

Need to add 4 infront of P on left hand side to balance number of atoms on both sides

The volume of 5.5 grams of carbon dioxide (CO2) at room temperature and pressure is approximately 2.42 dm³.

To calculate the volume of carbon dioxide (CO2) at room temperature and pressure (r.t.p), we can use the ideal gas law equation:

PV = nRT

Where:

P is the pressure

V is the volume

n is the number of moles

R is the ideal gas constant

T is the temperature

At r.t.p, the pressure is typically considered to be 1 atmosphere (atm) or 101.325 kilopascals (kPa). The temperature is approximately 298 Kelvin (K), which is equivalent to 25 degrees Celsius (°C).

First, we need to calculate the number of moles of carbon dioxide (CO2) using its mass and molar mass.

The molar mass of CO2 is calculated by adding the atomic masses of carbon (C) and two oxygen (O) atoms:

Molar mass of CO2 = (12.01 g/mol) + 2*(16.00 g/mol) = 44.01 g/mol

Now, we can calculate the number of moles using the given mass of 5.5 grams:

n = mass / molar mass = 5.5 g / 44.01 g/mol ≈ 0.125 mol

Next, we can rearrange the ideal gas law equation to solve for volume (V):

V = (nRT) / P

Substituting the known values into the equation:

V = (0.125 mol * 0.0821 L·atm/mol·K * 298 K) / 1 atm

V ≈ 2.42 dm³

Sulphur  is a main-group nonmetal element in period number 3 of the periodic table.

Elements can be classified as metals, non-metals, or metalloids. Metals are excellent conductors of heat and electricity, and are malleable (can be swaged into sheets) and ductile (can be stretched into wires). Most metals are solid at room temperature and have a characteristic silvery luster (except mercury, which is liquid). Nonmetals are (usually) poor thermal and electrical conductors and are not malleable or ductile. Many of the elemental nonmetals are gases at room temperature, others are liquids, and others are solids. Semimetals are intermediate in their properties. Their physical properties are similar to non-metals, but some can be made conductive under certain circumstances. These semiconductors are very important in computers and other electronic devices.

After considering the results of the classification tests, the possibilities can be narrowed down further by determining the melting point of the B Schiff addition product.

A compound's melting point is helpful in two ways: it provides information on the composition's identity and degree of purity. Impurities will affect a compound's melting point, resulting in broader and lower melting point ranges.

First, the solubility test must be performed in order to remove soluble contaminants from the target molecule. The desired chemical and the soluble impurities are dissolved in a minimum of near or boiling solvent once a suitable solvent has been selected. The solution is then given time to gradually cool.

Explanation:

upwelling is the process of winds blowing across the ocean surface to push water away.

Acetone enolate preferentially attack the benzaldehyde rather than another acetone molecule because it is a strong nucleophile which will attack the carbonyl of benzaldehyde and forms a B- carbonyl alkoxide ion.

Benzalacetone is the end product of the aldol condensation reaction between acetone and benzaldehyde. Acetone may be deprotonated to produce a nucleophilic enolate anion since it contains -hydrogens (on both sides). Because it is significantly more electrophilic than a ketone, the aldehyde carbonyl interacts with the enolate quickly. Since it dehydrates spontaneously under the reaction conditions, the original aldol adduct cannot be separated. However, the resulting, - α, β-unsaturated  ketone contains active hydrogen that can condense with additional benzaldehyde molecules.
