Help Me Find The Percent Composition On This Element

Answers

Answer 1

C12H22O11 has a mass composition of 42.1 percent, 6.48 percent hydrogen, and 51.4% oxygen.

What is Mass Composition?

By comparing an element's molar mass to the total molar mass of the compound as a whole, mass percent composition can be calculated. The final result of the calculation is a percentage that can be used to compare various compounds.

The exact number of atoms in the compound is shown by this formula.

The equation to calculate the percentage composition by mass of sodium is given below:

The exact number of atoms in the compound can be seen in this formula: mass of sodium = (22.99 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.5747 g % mass of sodium = (0.5747 g / 40.00 g/mol) x 100 = 1.43 % We can use the following equation to determine the percentage of the compound composed of oxygen by mass:

(mass of oxygen / molar mass of NaOH) x 100 = oxygen percentage = (16.00 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.400 g Oxygen percentage = (0.400 g / 40.00 g/mol) x 100 = 1.00% We can use the following equation to determine the percentage of hydrogen by mass:

(mass of hydrogen / molar mass of NaOH) x 100 = % mass of hydrogen % mass of hydrogen = (1.01 g/mol) x (1 mole NaOH / 40.00 g/mol) = 0.02525 g % mass of hydrogen = (0.02525 g / 40.00 g/mol) x 100 = 0.063% Na, 1.00% O, and 0.063% H The compound C12H22O11 has a  We can use the same approach as before to determine the percentage of C12H22O11's elements by mass.

Mass of Carbon = (1212.01) = 144.12 g Mass of Hydrogen = (221.01) = 22.22 g Mass of Oxygen = (11*16) = 176 g % Mass of Carbon = (144.12 / 342.30) x 100 = 42.1% % Mass of Hydrogen = (22.22 / 342.30) x 100 = 6.48% % Mass of Oxygen = (176 / 342.30) x 100.

When 30.0 g of carbon is heated with silicon dioxide, 28.2 g of carbon monoxide is produced. What is the percent yield of carbon monoxide for this reaction? SiO₂(s) + 3C(s) SiC(s) + 2CO(g)​

Answers

Answer: 60.5%

Explanation:

When 30.0 g of carbon is heated with silicon dioxide, 28.2 g of carbon monoxide is produced.  60.5% is the percent yield of carbon monoxide for this reaction.

The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield times by 100% divided by the experimental yield. The percent yield equals 100% if the theoretical and actual yields are equal.

SiO₂(s) + 3C(s)→ SiC(s) + 2CO(g)​

moles of carbon =30.0 / 12=2.5moles

3 moles of carbon give 1 moles of SiC

1 mole of carbon will give 1/3 moles of SiC

2.5 mole of carbon will give (1/3)×2.5 =0.83 moles of SiC

mass of  SiC = 0.83× 40.09=33.27

percent yield = (actual yield/theoretical yield) x 100%

percent yield= (28.2 / 33.27)x 100%

percent yield = 60.5%

Which of the following measurements
have four significant figures? Select all
that apply.

Answers

Answer:

1.001

120.0

Explanation:

Significant figures are used in science to determine the precision of a number. Depending on the decimal point, sig figs are counted in different ways.

Decimal Points

When counting sig figs, you always start at the first non-zero number. However, sometimes you start from the left, other times the right.

If the decimal point is present, start counting sig figs from the left.If the decimal point is absent, start counting sig figs from the right.

Remember to start counting at the first non-zero number.

For people in the Americas, there is a trick to remembering this.

If this decimal is Present, start from the Pacific. If it is Absent, start from the Atlantic.

This works because the Pacific ocean is to the left of the Americas, and the Atlantic is to the right.

4 Significant Figures

The number 1.001, has 4 significant figures. Since there is a decimal point, we start counting from the left. The first digit is not zero, so we count all four places as significant.

The number 120.0 also has 4 sig figs. Like the number above, we start counting from the left because of the decimal. The first digit on the left is not zero, so we once again count all 4 digits as significant.

Answers

The final pressure of the nitrogen gas with the increase in volume is 2.91 atm.

What is Boyle's Law?

Boyle’s law is a gas law that states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it.

The relation can be given as:

[tex]P_1V_1=P_2V_2[/tex]

The initial pressure of the gas, [tex]P_1[/tex] = 3.72 atm

The initial volume of the gas, [tex]V_1[/tex] = 8.56L

The final volume of the gas, [tex]V_2[/tex] = 10.94 L

Substituting the values, the final pressure [tex]P_2[/tex] is given as:

3.72 × 8.56 = [tex]P_2[/tex] × 10.94

[tex]P_2 =\frac{3.72 * 8.56}{10.94} \\\\P_2 =2.91 atm[/tex]

The term Ksp denotes the solubility product. It is generally used to predict the precipitation of reactions. The  Ksp of PbSO₄ is  6.24 × 10⁻⁷.

What is solubility product?

The solubility product of a sparingly soluble salt is defined as the product of the molar concentrations of its ions in a saturated solution of it at a given temperature. By knowing the solubility product of a substance, it is possible to predict whether a substance precipitate out or not.

In short, the precipitation of an ionic substance from the solution occurs when the ionic product exceeds the value of its solubility product at that temperature.

Here PbSO₄ dissociates as:

PbSO₄ → Pb²⁺ (aq) + SO₄²⁻ (aq)

Ksp = [Pb²⁺] [SO₄²⁻ ]

= [7. 9 × 10⁻⁴] [7. 9 × 10⁻⁴]

It is expressed as:

[tex]S_{\text{gas}} = K_{H} P_{\text{gas}}[/tex]

where,

[tex]S_{\text{gas}}[/tex] = Solubility of gas

[tex]K_{H}[/tex] = Henry's Law constant

[tex]P_{\text{gas}}[/tex] = Partial pressure of gas

Now put the values in above expression we get

[tex]S_{\text{gas}} = K_{H} P_{\text{gas}}[/tex]

0.080M = [tex]K_{H}[/tex] × 1.7 atm

[tex]K_{H} = \frac{0.080\ M}{1.7\ \text{atm}}[/tex]

      = 0.047 M/atm

Now we have to find the partial pressure of He

[tex]S_{\text{gas}} = K_{H} P_{\text{gas}}[/tex]

0.200 M = 0.047 M/atm × [tex]P_{\text{gas}}[/tex]

[tex]P_{\text{gas}} = \frac{0.200 M}{0.047\ \text{M/atm}}[/tex]

       = 4.25 atm

Thus from the above conclusion we can say that At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the  partial pressure of He would give a solubility of 0.200 M.

Chemical A has a toxicity level of 1 and chemical B has a toxicity level of 2. If a mixture of the two chemicals has a toxicity level of 3, what can we say about the results of the mixture

Answers

If chemical A has a toxicity level of one and chemical B has a toxicity level of two and the mixture of these two chemicals has a toxicity level of three, it means that the mixture of these two chemicals form a synergistic mixture.  This is condition is known as synergism.

A synergistic effect is exerted when a greater effect is exerted than the added effect of both the chemicals together. This is applicable for toxic chemicals as well as non-toxic chemicals. Synergism can be dangerous in the case of both toxicology or chemicals in general. The greater effect of toxic chemicals can result in a dangerous mixture, which could prove to have fatal effects in many cases.  The opposite of synergistic effect is antagonistic effect. The antagonistic effect is the effect where the overall effect of these two chemicals would be less than the sum of the effects imparted by the individual chemicals.
