Which of the following best helps to why the value of Delta H degree for the CaF_2 in water in positive? A. CaF_2(s) is insolubl
FromTheMoon [43]

Answer: Option (C) is the correct answer.

Explanation:

A positive value of enthalpy or \Delta H means that energy is being absorbed from the surrounding. As CaF_{2} has strong ionic bonding between both calcium and fluorine atoms. So, to break their bond we need to provide energy to it.

So, when CaF_{2} is dissolved in warm water then warm water molecules will bombard with the stable bond of CaF_{2}. As a result, the energy will transfer from water to the bond in order to break it. And, due to loss in internal energy then there will be consequent lowering of temperature.

When this bond is broken down then the atoms will separates into gaseous ions and these ions will be then surrounded by the water molecules. As ithe bond between  CaF_{2} is very strong hence, its lattice energy will be very high.

Thus, we can conclude that the statement Ca^{2+} ions have very strong interactions with F^{-} ions in the crystal lattice, best helps to why the value of \Delta H degree for the CaF_{2} in water in positive.

From the standards of the conversions of units:
1 in^3 = 0.01638 liters

To convert 320 in^3 into liters, we will simply use cross multiplication as follows:
displacement = (320 x 0.01638) / 1
                      = 5.2416 liters

The missing element  : ₇¹⁴N

<h3>Further explanation</h3>

Given

Reaction

₆¹⁴C ⇒X + ₋₁⁰e

Required

The missing element

Solution

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

  • alpha α particles ₂He⁴
  • beta β ₋₁e⁰ particles
  • gamma particles ₀γ⁰
  • positron particles ₁e⁰
  • neutron ₀n¹

In a decay reaction, the sum of the mass number and atomic number before and after the decay is the same.

The element X :

Atomic number = 6 + 1 =7

Mass number = 14 + 0 = 14
