How does the color intensity of cis and trans complexes typically vary, and what is the underlying reason for this difference?

Answer:

The mass of hydrogen gas liberated is 0.6 g.

Explanation:

Given data:

Mass of Mg = 6.5 g

Mass of hydrogen gas liberated = ?

Solution:

Chemical equation:

Mg + 2HCl     →    MgCl₂ + H₂

Now we will calculate the number of moles of Mg.

Number of moles = mass / molar mass

Number of moles = 6.5 g/ 24 g/mol

Number of moles = 0.3 mol

Now we will compare the moles of Mg with hydrogen gas.

            Mg         :          H₂

             1           :           1

             0.3       :        0.3

Mass of H₂:

Mass = number of moles × molar mass

Mass = 0.3 mol × 2 g/mol

Mass = 0.6 g

Answer: Rb is more reactive

Explanation: The reason rubidium is more reactive is because it loses its valence electron more readily than Mg does.

Answer:

Rb

Explanation:

Mg has 2 valence electrons to loose vs Rb has 1 valence electron to loose.

Rb wins because losing 1 electron is easier than having to lose 2, which means Rb is more reactive ("ready" to react).

Explanation:

The new pressure will be 19.2 atm when the temperature is increased to 145.0 °C and the volume expands to, 3156 L.

To solve the problem, we need to use the combined gas law:

(P₁ V₁ ) / T₁  = (P₂ V₂ ) / T₂

P₁  = initial pressure

V₁  = initial volume

T₁  = initial temperature,

P₂  = final pressure

V₂  = final volume

T₂  = final temperature

Firstly, convert the initial temperature to Kelvin:

T₁ is equal to -46.0°C + 273.15

= 227.15 K

Next, we can put in the given values to find the initial pressure:

(P₁ V₁) / T₁ = (4.80 atm)(632 L) / 227.15 K

P₁ = 13.34 atm

Use combined gas law again to calculate the final pressure:

(P₁ V₁) / T₁ = (P₂ V₂) / T₂

P₂ = (P₁ V₁ T₂) / (V₂ T₁)

Let's put the given values:

P₂ = (13.34 atm)(632 L)(145.0 °C + 273.15) / (3156 L)(227.15 K)

P₂ = 19.2 atm (rounded to two decimal places)

Thus, the new pressure will be 19.2 atm when the temperature is increased to 145.0 °C and the volume expands to, 3156 L.

Answer:

Explanation:During the nifty home experiment, a playing card was placed on top of a glass and then a quarter was placed on top of the card. When the card was pushed, the quarter fell into the glass. Why did the quarter fall into the glass? The quarter fell in the glass because of gravity.

The situation described can be solved using the combined gas law, which states:

(P1 x V1) / (T1) = (P2 x V2) / (T2)

Where P1, V1, and T1 are the initial pressure, volume, and temperature of the gas, respectively. P2, V2, and T2 are the final pressure, volume, and temperature of the gas, respectively.

To solve for the final temperature (T2), we can rearrange the equation as:

T2 = (P2 x V2 x T1) / (P1 x V1)

Let's plug in the given values:

P1 = 700 mm

P2 = 800 mm

V1 = V2 (since the volume is doubled)

T1 = 0°C + 273.15 = 273.15 K (converting to Kelvin)

So, we have:

T2 = (800 mm x 2V1 x 273.15 K) / (700 mm x V1)

T2 = (1600/7) x 273.15 K

T2 = 392.2 K

Therefore, the final temperature at which the volume of gas would be doubled, if the pressure increases from 700-800 mm and the gas is initially at 0°C, is approximately 392.2 Kelvin (which is approximately 119°C or 246°F).

Lewis structure is the electron dot representation of the atomic and molecular bonds of the molecules. Trigonal planar is the shape of the formaldehyde.

A trigonal planar shape of the molecule is the arrangement of the central atom attached to the other three atoms making them look triangle-shaped.

The attachment of the carbon to the two hydrogens and one oxygen atom can be given by the VSEPR theory. The number of the electron pair in the molecule is 3 making them \(\rm sp_{2}\) hybridized and hence have a trigonal planar shape.

Therefore, option D.  trigonal planar is the shape.

Let's call the new energy unit 'pit' named after you. And let's define 1 pit as equal to 1/10 of a calorie. So, 1 pit is equal to 0.0001 Calories.

Energy is defined via work, so SI unit of energy is same as the unit of work, that is joule.

Let's call the new energy unit 'pit' named after you. And let's define 1 pit as equal to 1/10 of a calorie

To relate this new unit to joules, we need to use the conversion factor between calories and joules. This conversion factor is 1 calorie = 4.184 joules. Therefore, we can say that:

1 pit = 1/10 calorie = (1/10) x 4.184 joules = 0.4184 joules

So, 1 pit is equal to 0.4184 joules.

1 pit = 1/10 calorie = (1/10) x 0.001 Calories = 0.0001 Calories

So, 1 pit is equal to 0.0001 Calories.

In salt hydrolysis, the conjugate bases of weak acids yield basic solutions, while the conjugate acids of weak bases yield acidic solutions. This phenomenon occurs because the hydrolysis of a salt produces either hydroxide ions or hydronium ions, depending on the nature of the salt.

For example, when the salt of a weak acid and a strong base is hydrolyzed, the conjugate base of the weak acid is formed, which acts as a weak base. This weak base can then react with water to produce hydroxide ions, leading to an increase in the pH of the solution and a basic solution. Conversely, when the salt of a weak base and a strong acid is hydrolyzed, the conjugate acid of the weak base is formed, which acts as a weak acid. This weak acid can then react with water to produce hydronium ions, leading to a decrease in the pH of the solution and an acidic solution.

It is important to note that the strength of the acid or base will also influence the pH of the solution, as stronger acids and bases will have a greater impact on the pH. Additionally, the concentration of the salt and the water will also impact the degree of hydrolysis and the resulting pH of the solution.
