Answer:
More generally, when a carbon atom is bonded to four other atoms, the molecule (or part of a molecule) will take on a tetrahedral shape similar to that of methane. (if this doesn't help sorry :<)
Answer:
you need to show more thing cause we not going to know what we have to do
Explanation:
and show more detaills
<u>Given:</u>
Mass of Ag = 1.67 g
Mass of Cl = 2.21 g
Heat evolved = 1.96 kJ
<u>To determine:</u>
The enthalpy of formation of AgCl(s)
<u>Explanation:</u>
The reaction is:
2Ag(s) + Cl2(g) → 2AgCl(s)
Calculate the moles of Ag and Cl from the given masses
Atomic mass of Ag = 108 g/mol
# moles of Ag = 1.67/108 = 0.0155 moles
Atomic mass of Cl = 35 g/mol
# moles of Cl = 2.21/35 = 0.0631 moles
Since moles of Ag << moles of Cl, silver is the limiting reagent.
Based on reaction stoichiometry: # moles of AgCl formed = 0.0155 moles
Enthalpy of formation of AgCl = 1.96 kJ/0.0155 moles = 126.5 kJ/mol
Ans: Formation enthalpy = 126.5 kJ/mol
According to the research, the correct option is remove. An air-to-air heat pump removes heat from the outside air and deposits it in the conditioned space.
<h3>What are heat pumps?</h3>
It is characterized by being a thermal machine or a device based on thermodynamics that, through an absorption process, takes heat from one place and transfers it to another, that is, it extracts heat from a cold source to a hot one.
An air-to-air heat pump starts by sucking in outside air or recovers heat from outside and transfers it to a higher temperature level in the ambient air, raising the temperature of the room, being adjustable to adapt to the heating needs of the conditioned space.
Therefore, we can conclude that according to the research, the correct option is remove. An air-to-air heat pump removes heat from the outside air and deposits it in the conditioned space..
