Explanation:

Since 0.865 is smaller than 0.89, hydrogen (H2) is the limiting reactant in this reaction.

To determine the limiting reactant, we need to compare the moles of each reactant to the stoichiometric ratio of the balanced equation. The balanced equation for the reaction between hydrogen and oxygen to form water is:

2H2 + O2 -> 2H2O

According to this equation, 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water.

To determine which reactant is limiting, we can use the mole ratio of the reactants in the equation. For every 1 mole of oxygen, we need 2 moles of hydrogen. So, for 0.89 moles of oxygen, we would need 1.78 moles of hydrogen.

Since we only have 1.73 moles of hydrogen, it is the limiting reactant. This means that all 0.89 moles of oxygen will react completely with 1.73 moles of hydrogen, and any remaining hydrogen will be left over after the reaction is complete.

Answer:

75.92

Explanation:

A)the % abundance adds up to 100, so adding all the % abundances of Ge:

20.52 + 27.45 + 7.76 + 36.52 = 92.25

The remaining % abundance is:

100 - 92.25 = 7.75%

B) Using this formula:

\(atomic \: mass = \frac{sum \: of \: (\% \: isotope \: abundance \times isotope \: mass)}{100} \)

\(72.63 = \frac{(20.52 \times 69.92) + (27.45 \times 71.93) + (7.76 \times 72.92) + (36.52 \times 73.92) + (7.75x)}{100} \)

multiply both sides by 100 to get rid of the fraction:

\(7263= {(20.52 \times 69.92) + (27.45 \times 71.93) + (7.76 \times 72.92) + (36.52 \times 73.92) + (7.75x)}{} \)

multiplying each bracket:

\(7263 = 1434.7584 + 1974.4785 + 565.8592 + 2699.5584 + 7.75x\)

adding up the terms:

\(7263 = 6674.6545 + 7.75x\)

subtract 6674.6545 on both sides to give:

\(588.3455 = 7.75x\)

divide both sides by 7.75:

\(x = \frac{588.3455}{7.75} = 75.92 \: (2dp)\)

The equilibrium will favor the products (benzoic acid and NaCl) because HCl has a lower pKa. The correct answer is (d).

The pKa of HCl is -7, while the pKa of benzoic acid is 4.2. This means that HCl is a much stronger acid than benzoic acid.

When benzoic acid reacts with sodium hydroxide (NaOH), it forms sodium benzoate and water. This reaction is a type of acid-base reaction, where benzoic acid acts as an acid and NaOH acts as a base.

When sodium benzoate is treated with hydrochloric acid (HCl), it reacts to form benzoic acid and sodium chloride (NaCl). This reaction is also a type of acid-base reaction, where sodium benzoate acts as a base and HCl acts as an acid.

The equilibrium of the reaction between sodium benzoate and HCl will depend on the relative strengths of the two acids. Since HCl is a much stronger acid than benzoic acid, it will be more likely to react with sodium benzoate than benzoic acid will be to react with NaOH.

Therefore, the equilibrium will favor the products (benzoic acid and NaCl) because HCl has a lower pKa. The correct answer is (d).

The correct answer is 0.15.

We are aware that there is 0.05 mol of an unidentified hydrocarbon we will refer to as "X" and that its burning produces 6.6 g of carbon dioxide and 3.6 g of water.

These quantities might be converted to moles by applying the following formula:

amount= mass/ relative atomic mass

Thus, the following equation may be written for H2O: moles = 3.6 / 18 = 0.2 and for CO2: moles = 6.6 / 44 = 0.15.

0.05X + x'O2 = 0.15CO2 + 0.2H2O

This may be made simpler by dividing through by 0.05 (this step is likely to be the most helpful to you), resulting in:

1 x + x O2 = 3 co2 + 4 H2O

The hydrocarbon must have been the source of all the carbon in the carbon dioxide and all the hydrogen in the water.

Accordingly, 4 x 2 = 8 moles of H and 3 x 1 = 3 moles of C.

There are 3/1 = 3 Cs and 8/1 = 8 Hs in one X molecule.

This clearly identifies C3H8 or propane as the hydrocarbon X (dividing by 1 seems unnecessary, but it illustrates the process to use if there were more than one mol of X in the first equation).

The supernova explosion of Type 1a supernovae is so bright that they are used as "standard candles" in astronomy.

A Type la supernova results from the explosion of a former high mass star, fusion of hydrogen on the outside of a white dwarf and collision between a White dwarf and its binary companion. Feedback suggests that if a white dwarf accretes enough mass to enlarge it beyond 1.4 solar masses, the degenerate carbon core will not be able to resist gravitational collapse and the star will fuse carbon in a thermonuclear runaway explosion, a Type La supernova.

Type 1a supernova results from the explosion of a white dwarf star that has gained additional mass and become unstable. A white dwarf is a dense core that remains after the outer layers of a star have been ejected during a nova. They are believed to exist in binary star systems, where they capture gas from their companion.

If the white dwarf gains enough mass, the carbon core is forced into rapid fusion, releasing a tremendous amount of energy and causing the star to explode. The supernova explosion of Type 1a supernovae is so bright that they are used as "standard candles" in astronomy.

The mass of \(Al_{2} S_{3}\) produced is 15.616 grams.

The reaction taking place is as follows:

\(2Al+ 3S\) →\(Al_{2} S_{3} (s)\)

Moles of Al = mass/molar mass = 10.0g/27.0g/mol

= 0.370 mol

Moles of S = mass/molar mass = 15.0g/(32.065g/mol)

= 0.468 mol

Al and S reacts in the molar ratio of 2:3.

2 moles of Al reacts with 3 moles of S

0.370 moles of Al will react with S = (3/2)*0.370mol

= 0.555 mol

Similarly, 0.468 moles of S will react with Al = 2/3 *0.468mol

= 0.312 mol

Thus, Al is in excess and S is the limiting reactant (some of Al will be left over ,S will completely react)

So, moles of \(Al_{2} S_{3}\) produced=1/3*0.312 mol of S

Answer: Both the given species are isotopes of the same element.

Explanation:

An isotope is defined as the chemical species that have the same atomic number but a different mass number.

The atom consists of 3 subatomic particles:

An atomic number is defined as the number of protons or number of electrons present in a neutral atom. It remains specific for a particular element.

Mass number is defined as the sum of the number of protons and neutrons present in the nucleus of an atom.

Given values:

For isotope 1:

Number of protons = 11 = atomic number

Number of neutrons = 13

Mass number = 11 + 13 = 24

For isotope 2:

Number of protons = 11 = atomic number

Number of neutrons = 12

Mass number = 11 + 12 = 23

As the atomic number of both the isotopes is the same. Thus, they belong to the same elements.

The % RSD of a 1.00 ppm standard solution prepared by pipetting 10 µL of a 1000 ppm (stock solution) will be 0.1%. The relative standard deviation (RSD) is used to compare the variability in a set of measurements to the mean of the set.

It is the ratio of the standard deviation to the mean. RSD = (standard deviation / mean) × 100. The percentage RSD for a 1.00 ppm standard solution prepared by pipetting 10 µL of a 1000 ppm (stock solution) is calculated as follows: Concentration of the stock solution = 1000 ppm

Volume of the stock solution pipetted

= 10 µL Volume of the diluted solution made

= 1000 µL (10 µL × 100)

Concentration of the diluted solution = (1000 ppm × 10 µL) / 1000 µL

= 10 ppm

Relative standard deviation (%RSD)

= (Standard deviation / Mean) × 100

= (0.01 / 10) × 100 = 0.1%.
