The balanced equation for the reaction is as follows
Cu₂O + 2HCl ---> 2CuCl + H₂O
Molar ratio of Cu₂O to CuCl is 1:2
mass of Cu₂O reacted - 73.5 g
Number of moles of Cu₂O reacted - 73.5 g / 143 g/mol = 0.51 mol
According to the molar ratio,
when 1 mol of Cu₂O reacts then 2 mol of CuCl is formed
therefore when 0.51 mol of Cu₂O reacts then - 2 x 0.51 mol of CuCl is formed
number of CuCl moles formed - 1.02 mol
mass of CuCl formed - 1.02 mol x 99 g/mol = 101 g
mass of CuCl formed is 101 g
Answer:
The different magnetic shielding effects of the carbonyl double bond in CH0, the CH₂ (a) and CH₂ (b) protons show different chemical shifts
Because the degree of shielding depends on electron density round the proton, the neighboring carbonyl group will increase this density in geranial form.
Now in CH₂ the electron density is increased around CH₂ (a) protons in neral form due to the carbonyl group, and thus it has a lower z values than the corresponding geranial form.
In the case of CH₃ (b) protons. thus they have lower z values and higher chemical shift than the corresponding nera form.
Explanation:
Solution
Due to the different magnetic shielding effects of the carbonyl double bond in CH0, the CH₂ (a) and CH₂ (b) protons show different chemical shifts.
Since the degree of shielding depends on electron density round the proton, the neighboring carbonyl group will increase this density in geranial form more in case of CH₃ (b) protons. thus they have lower z values and higher chemical shift than the equivalent nera form.
Similarly, the electron density is increased around CH₂ (a) protons in neral form due to the carbonyl group, and thus it has a lower z values than the equivalent geranial form.
Answer:
1- Environmental Value System or EVS is a worldview that molds the way both individuals and the societies they form perceive and therefore evaluate environmental concerns.
2-Entropy/ the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
3-Equilibrium/a state of balance between opposing forces or actions that is either static
4-Feedback/a return of information about a result or the returned portion of a process.
5-Feedback,negative/ is a self-regulatory system in which it feeds back to the input a part of a system's output so as to reverse the direction of change of the output.
6-Feedback,positive/ is the amplification of a body's response to a stimulus.
7-Gaia/ all organisms and their inorganic surroundings on Earth are closely integrated to form a single and self-regulating complex system
8-Model/a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Answer: true
Asexual reproduction is the process by which an organism is produced from a single parent cell. There are four major forms of asexual reproduction - budding, binary fission, regeneration and parthenogenesis. ... Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts.

Answer:
hydrogen bonds are a type of a chemical bond that are with the molecules or we can say that it is a bond which connects atoms together to form a compound or a molecule. an example will be water. this bonding occurs between hydrogen and four other elements which are Oxygen, Fluorine, Nitrogen and Carbon.
