Hopefully this will help Im pretty sure this is the answer
Answer:
B. is the answer
Explanation:
Energy in form of heat is transferred from the warmer mashed potatoes to the cooler spoon.
Answer:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp
Explanation:
The reaction is:
2NO + 2H₂ → N₂ + 2H₂O
The expression for Kp (pressure equilibrium constant) would be:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²
There is another expression for Kp, where you work with Kc (equilibrium constant)
Kp = Kc (R.T)^Δn
where R is the Ideal Gases constant
T° is absolute temperature
Δn = moles of gases formed - moles of gases, I had initially
Answer:
F⁻(aq) + H⁺(aq) ⇄ HF(aq)
Explanation:
When aqueous solutions of potassium fluoride and hydrochloric acid are mixed, an aqueous solution of potassium chloride and hydrofluoric acid results. The corresponding molecular equation is:
KF(aq) + HCl(aq) ⇄ KCl(aq) + HF(aq)
The full ionic equation includes all the ions and the molecular species. HF is a weak acid so it exists mainly in the molecular form.
K⁺(aq) + F⁻(aq) + H⁺(aq) + Cl⁻(aq) ⇄ K⁺(aq) + Cl⁻(aq) + HF(aq)
The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the molecular species.
F⁻(aq) + H⁺(aq) ⇄ HF(aq)
The answer to this question depends on the specific context in which urban and industrial development is taking place. However, in general, these sectors often practice improper and mismanaged sewage systems due to a lack of understanding or awareness of the potential environmental impacts of their activities.
Urban and Industrial development:
An agrarian economy becomes a manufacturing economy through the process of industrialization. Manual and specialised employees are replaced by assembly lines and mass production. In the past, this process has sparked urbanisation by generating economic expansion and employment possibilities that entice people to live in cities.
When one or more factories are built in an area, urbanisation usually starts since there is a great need for factory workers. The factories are subsequently followed by other enterprises, like those that produce buildings, sell goods online, and offer services to consumers. As a result, there are more occupations created and housing needs are increased, creating an urban area.
In many cases, engineers and other technical professionals are present in these sectors but are not consulted or involved in the decision-making process regarding sewage systems. This can lead to a situation in which the systems are not designed or operated in an environmentally sustainable manner.
