Answer: The natural gas transmission system is primarily a giant international pipeline network, consisting of large, medium, and small-sized pipes. ... If transport by pipeline is not feasible, then natural gas is usually transported in its liquefied state, which has a temperature of -162 ° C and its density is lower than waters.
Explanation: Potential energy is stored energy and the energy of position. Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy
The first shell can only hold 2 electrons, but the pupil placed in 8 electrons.
The second shell can hold up to 8 electrons, but the pupil only placed in 2 electrons.
Flourine only has 9 total electrons, yet there are 10 electrons in the diagram.
Answer:
Molecular- compound B, Ionic - compound A
Explanation:
Molecular compounds are compounds containing two or more non-metal for example carbon dioxide and covalent in nature. They usually have low melting and boiling points and will vaporized faster. Compound A on the other hand is ionic; they usually have high melting and boiling points and when dissolved in water they dissociate into ions ( actions and anions)
Answer:
0.66 moles of NaClO were originally added
Explanation:
When NaClO is added to water, the equilibrium that occurs is:
NaClO(aq) + H₂O(l) ⇄ HClO(aq) + OH⁻(aq)
Where Kb is:
Kb = [HClO] [OH⁻] / [NaClO]
You can obtain Kb from Ka, thus:
Kb = Kw / Ka = 1x10⁻¹⁴ / 3.0x10⁻⁷
Kb = 3.33x10⁻⁸
As pH = 10.50;
pOH = 14 - 10.50 = 3.50
[OH⁻] = 10^{-3.50}
[OH⁻] = 3.16x10⁻⁴M
As OH⁻ and HClO comes from the same equilibrium, [OH⁻] = [HClO]
Replacing in Kb expression:
Kb = [HClO] [OH⁻] / [NaClO]
3.33x10⁻⁸ = [3.16x10⁻⁴] [3.16x10⁻⁴] / [NaClO]
[NaClO] = 0.333M
As there are 2.0L of NaClO solution, moles added were:
2.0L * (0.33moles / L) =
<h3>0.66 moles of NaClO were originally added</h3>
Answer:
Chlorine ion will attack the carbocation and double bond will not be created
Explanation:
The use of concentrated hydrochloric acid wiill be a poor choice as the acid catalyst for the formation of cyclohexane by dehydration of cyclohexanol because of the following reasons:
1) There will be presence of chlorine ions and they will attack the carbocation to form a single bond.
2) The formation of double bond will not occur in the process.
Therefore, it is a poor choice to use concentrated hydrochloric acid as the acid catalyst for the formation of cyclohexane by dehydration of cyclohexanol.
