The peroxide addition would yield a product that is different from the antiperoxide addition

Markovnikov's rule states that when a protic acid HX is added to an alkene, the acid hydrogen (H) forms a bond with the carbon atom that has the greatest number of hydrogen atoms, while the halide (X) group forms a bond with the carbon atom that has the fewest hydrogen atoms.

This can be summed up with the phrases "the rich get richer" and "the poor get poorer" in terms of hydrogen. This fundamental principle of alkene chemistry aids in predicting the results of addition reactions.

The half-life of a first-order reaction is given by the following equation:

t(1/2) = ln(2)/k

where t(1/2) is the half-life and k is the rate constant.

From the given information, we know that the partial pressure of FC1O2(g) falls from 0.080 atm to 0.010 atm over 48 minutes. We can use this information to calculate the rate constant as follows:

ln([FC1O2]t/[FC1O2]0) = -kt

where [FC1O2]t is the concentration (in atm) at time t, [FC1O2]0 is the initial concentration (in atm), and k is the rate constant.

Substituting the given values, we get:

ln(0.010/0.080) = -k(48)

Solving for k, we get:

k = 0.1225 min^-1

Now, we can use the equation for the half-life to calculate the answer:

t(1/2) = ln(2)/k

t(1/2) = ln(2)/0.1225

t(1/2) = 5.66 min (rounded to two significant figures)

Therefore, the half-life of the decomposition reaction is 5.66 minutes.

The uncertainty in the baseball's position is approximately 6.97 × 10⁻³⁶ m.

Using the uncertainty principle, ∆x∆p ≥ h/4π, we can solve for the uncertainty in position:

∆x ≥ h/4π∆p

First, we need to convert the velocity from mph to m/s:

100 mph = 44.7 m/s

Next, we need to convert the momentum from kg · m/s to kg · m/s²:

7.7 kg · m/s = 7.7 N · s

Now we can solve for the uncertainty in position:

∆x ≥ h/4π∆p = (6.626 × 10⁻³⁴ J · s)/(4π × 7.7 N · s)

                     = 6.97 × 10⁻³⁶ m

As a result, the uncertainty in baseball's location is around 6.97 × 10⁻³⁶ m. This value is incredibly small and practically impossible to measure, indicating that the uncertainty in measuring the mass has no significant effect on the uncertainty in position.

Answer: c. endothermic reaction.

Explanation: In an endothermic reaction, energy is absorbed or required to break the bonds in the reactants. This means that more energy is required to break the bonds than is released by the formation of new bonds in the products, resulting in a net absorption of energy. In this case, the amount of energy required to break the bonds (1254 kJ) is higher than the energy produced by breaking the bonds (1001 kJ), indicating that the reaction requires an input of energy and is therefore endothermic.

Answer:

c. endothermic reaction

Explanation:

The given information states that the amount of energy required to break the bonds of the covalent compound is 1254 kJ, and the energy produced as a result of breaking the bonds is 1001 kJ.

In an endothermic reaction, the energy required to break the bonds is greater than the energy released or produced. This means that more energy is absorbed from the surroundings than is released during the reaction. In this case, since the energy required to break the bonds (1254 kJ) is greater than the energy produced (1001 kJ), it indicates that the reaction requires an input of energy from the surroundings, making it an endothermic reaction.

Option c, "endothermic reaction," is the correct answer based on the given information.

The acidity or alkalinity of a solution depends upon its hydronium ion concentration and hydroxide ion concentration. Here among the given options, all the aqueous solutions are considered as basic. The correct option is E.

The pH of a solution is defined as the negative logarithm to the base 10 of the activity of hydrogen ions. At 298 K, for pure water or in a neutral solution the pH is found to be 7.

For an acidic solution, the concentration of H₃O⁺ is greater than 10⁻⁷ M and the pH will be less than 7. For a basic solution, the concentration of  H₃O⁺ is  less than 10⁻⁷ M and hence the pH will be greater than 7.

The enthalpy change for the given reaction is 1344 kJ/mol.

First, we need to write the balanced chemical equation for the given reaction:

HCN(g) + 2 H2(g) → CH3NH2(g)

To calculate the enthalpy change (ΔH) for this reaction, we need to subtract the total energy of the reactants from the total energy of the products. We can do this by calculating the energy required to break the bonds in the reactants and the energy released when new bonds are formed in the products.

Reactants:

HCN(g): 1 C-N bond (305 kJ/mol) + 1 C-H bond (413 kJ/mol) + 1 N-H bond (391 kJ/mol) = 1109 kJ/mol

2 H2(g): 4 H-H bonds (4 x 432 kJ/mol) = 1728 kJ/mol

Total energy of reactants: 1109 kJ/mol + 1728 kJ/mol = 2837 kJ/mol

Products:

CH3NH2(g): 1 C-H bond (413 kJ/mol) + 3 C-N bonds (3 x 305 kJ/mol) + 7 H-H bonds (7 x 432 kJ/mol) = 4181 kJ/mol

Total energy of products: 4181 kJ/mol

ΔH = (total energy of products) - (total energy of reactants)

ΔH = 4181 kJ/mol - 2837 kJ/mol

The time it takes for a radio message to travel from a space probe on Mars to Earth when the planets are at a distance of 56 million km can be calculated using the speed of light which is about 299,792,458 meters per second.

To convert the distance from kilometers to meters, we multiply 56 million km by 1000 to get 56 x 10^6 km = 5.6 x 10^10 m.

The time it takes for a radio signal to travel from Mars to Earth is:

time = distance/speed

time = 5.6 x 10^10 m / 299,792,458 m/s

time = 187 seconds

Therefore, a radio message from a space probe on Mars would take about 187 seconds, or just over 3 minutes, to reach Earth when the planets are at a distance of 56 million km.

Explanation:

The energy of a single photon can be calculated using the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J.s), c is the speed of light (2.998 x 10^8 m/s), and λ is the wavelength of the photon.

To dissociate one mole of Cl2 molecules, we need 239 kJ of energy. This corresponds to 239,000 J/mol of Cl2.

Now we can use the relationship between energy and the number of photons absorbed: E = Nhf, where N is the number of photons absorbed, h is Planck's constant, and f is the frequency of the absorbed photons.

We can relate the frequency of the absorbed photon to its wavelength using c = λf. Solving for f gives f = c/λ.

Combining these equations, we get E = Nh(c/λ), or N = E/(hc/λ). Substituting the value of E for the energy required to dissociate one mole of Cl2, we get:

N = (239,000 J/mol) / [(6.626 x 10^-34 J.s) x (2.998 x 10^8 m/s) / λ]

Solving for λ, we get:

λ = hc / (239,000 J/mol) = (6.626 x 10^-34 J.s x 2.998 x 10^8 m/s) / 239,000 J/mol

λ = 8.44 x 10^-7 m

Therefore, the wavelength of the photon required to dissociate one Cl2 molecule is approximately 8.44 x 10^-7 meters (or 844 nanometers).
