These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has.

Answer:

The number becomes smaller

Explanation:

Volume = 5800mL

To be converted to L

The relationship between mL and Liters is given as;

1 L = 1000 mL

This means that;

1 L = 1000 mL

x L = 5800 mL

x = 5800 / 1000 = 5.8 L

Comparing 5.8 with 5800, the number becomes smaller.

Answer:

2 mol H₂O

Explanation:

With the reaction,

1.55 moles of O₂ would react completely with ( 2*1.55 ) 3.1 moles of H₂. There are not as many moles of H₂, thus H₂ is the limiting reactant.

Now we calculate the moles of H₂O produced, starting from the moles of limiting reactant:

The number of moles of H₂O that could be produced in the reaction is 2.00 moles

From the question,

We are to determine the number of moles of H₂O that could be produced.

The given balanced chemical equation is

2 H₂(g) + O₂(g) → 2 H₂O(g)

This means,

2 moles of H₂(g) reacts with 1 mole of O₂(g) to produce 2 moles of H₂O

From the given information

Number of moles of H₂ present = 2.00 moles

and

Number of moles of O₂ present = 1.55 moles

Since,

2 moles of H₂(g) reacts with 1 mole of O₂(g) to produce 2 moles of H₂O

Then,

The 2.00 moles of H₂(g) will react with 1.00 mole of O₂(g) to produce 2.00 moles of H₂O

∴ 2.00 moles of H₂O will be produced during the reaction

(NOTE: Only 1.00 mole of the O₂(g) will react, meaning O₂(g) is the excess reactant)

Hence, the number of moles of H₂O that could be produced in the reaction is 2.00 moles

Answer:

Ksp = 3.24 x 10⁻⁴

Explanation:

The dissociation equilibrium for a generic salt AB is:

AB(s) ⇄ A⁺(aq) + B⁻(aq)

              s            s

For instance, the expression for the Ksp constant is:

Ksp = [A⁺] [B⁻] = s x s = s²

According to the problem, 0.0180 mol of the salt is soluble in 1.00 L os water. That means that the solubility of the salt (s) is equal to 0.0180 mol per liter.

s = moles of solute/L of solution = 0.0180 mol/L

Thus, we calculate Ksp from the s value as follows:

Ksp = s² = (0.0180)² = 3.24 x 10⁻⁴

Explanation:

Hello!

In this case, for the undergoing chemical reaction, since 45.0 g of aluminum react, based on the 2:3 mole ratio with sulfuric acid, we can compute the required moles  as shown below:

[tex]n_{H_2SO_4}=45.0gAl*\frac{1molAl}{27.0gAl} *\frac{3molH_2SO_4}{2molAl} =2.50molH_2SO_4[/tex]

Next, since the molarity of a solution is computed based on the moles and volume (M=n/V), we can compute the required volume of sulfuric acid as shown below:

[tex]V=\frac{n}{M}=\frac{2.50mol}{15.0mol/L}=0.167L[/tex]

That in mL is 167 mL.

Moreover, for the percent yield, we compute the grams of aluminum sulfate that are produced based on the required 2.50 moles of sulfuric acid:

[tex]m_{Al_2(SO_4)_3}=2.50molH_2SO_4*\frac{1molAl_2(SO_4)_3}{3molH_2SO_4}*\frac{342.15gAl_2(SO_4)_3}{1molAl_2(SO_4)_3} \\\\m_{Al_2(SO_4)_3}=285.13gAl_2(SO_4)_3[/tex]

Therefore the percent yield is:

[tex]Y=\frac{112g}{285.13g}*100\%\\\\Y=39.3\%[/tex]

Answer:

96.72 m/min

Explanation:

The following data were obtained from the question:

Time (t) = 56.7 s

Distance (d) = 100 yard

Rate (R) =?

Next, we shall convert 56.7 s to minutes. This can be obtained as follow:

60 s = 1 min

Therefore,

56.7 s = 56.7 s × 1 min /60 s

56.7 s = 0.945 min

Next, we shall convert 100 yard to metre (m). This can be obtained as follow:

1 yard = 0.914 m

Therefore,

100 yard = 100 yard × 0.914 m /1 yard

100 yard = 91.4 m

Finally, we shall determine the rate of the swimmer as follow:

Time (t) = 0.945 min

Distance (d) = 91.4 m

Rate (R) =?

R = d/t

R = 91.4/0.945

R = 96.72 m/min

Thus the rate of the swimmer is 96.72 m/min

Spectrographs are useful to astronomers as they  help in studying the composition of a star as each component absorbs light at specific wavelengths.

It is defined as a graph which depicts the spectral information about the component. Spectrographs consisting of lines  are  called atomic spectra as the lines represent wavelengths which are radiated from atoms when electrons jump or make a transition from one energy level to another.

Band spectra is given to a group of lines spectrum which are so close that they appear like a band . They are produced by molecules when they radiate their vibrational or rotational energies.

Amount of light which is absorbed is unique for each element and hence astronomers can measure  the position of lines  to determine which elements are present in the target.

Answer:

P₂ = 607 mmHg

Explanation:

Given data:

Initial volume = 4.5 L

Final volume = 5.6 L

Initial pressure = 756 mmHg

Final pressure = ?

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

756 mmHg × 4.5 L = P₂ × 5.6 L

P₂ = 3402 mmHg. L/5.6 L
