Answer:
a) N2 (g) + H2 = 2 NH3
b) You have to state the mass of hydrogen
Answer: 1.88times as that of Cl2
Explanation:
According to Graham law of effusion , the rate of effusion is inversely proportional to the square root of the molar mass
Rate= 1/√M
R1/R2 =√M2/M1
Let the rate of diffusion of Ne= R1
And rate of diffusion of Cl2 = R2
M1 ,molar mass of Ne= 20g/mol
M2,molar mass of Cl2 =71g/mol
R1/R2 = √ (71/20)
R1/R2 = 1.88
R1= 1.88R2
Therefore the Ne effuses at rate that is 1.88times than that of Cl2 at the same condition.

How many bonding electrons are present in this compound?
How many lone pair (non-bonding) electrons are present in this compound?
Answer:
Valence electrons in XeCl2 = 8 + 7 + 7 = 22.
Bonding electrons = 4.
Nonbonding electrons = 18.
Explanation:
Hello.
In this case, you can see the Lewis structure on the attached picture, in which you can see that there are since xenon has 8 valance electrons and each chlorine has 7 valence electrons, the total amount of valence electrons is:
Valence electrons in XeCl2 = 8 + 7 + 7 = 22.
Moreover, since each chlorine atom is bonding with one of the eight electrons of xenon (Lewis structure), we can see there are 4 bonding electrons.
Finally, since there are six nonbonding electrons per chlorine atom and six nonbonding electrons in xenon, the overall nonbonding electrons are:
Nonbonding electrons in XeCl2 = 6 + 6 + 6 = 18.
Regards.
Answer : Protein
Explanation : When the scientist isolated the water soluble compound from the spider venom it had elements such as carbon,nitrogen, hydrogen and oxygen in its chemical structure this gives an assumption of the compound being a protein. But, further confirmation was given when it was injected under the mice skin and which broke down the structural materials in the cell membrane, this is one of the property of protein. And he is going to find out about its toxicity to humans.
The compound from spider venom is likely an alkaloid, a class of compounds often involved in cell membrane disruption and known for their psychotropic and physiological effects on humans. It might have potential medicinal uses like other animal toxins currently under research.
The compound described in the question, which is derived from spider venom and contains nitrogen, carbon, hydrogen, and oxygen, is most likely a type of alkaloid. Alkaloids are naturally occurring chemical compounds containing mostly basic nitrogen atoms. They have a range of effects on living organisms but are often involved in cell membrane disruption. Examples include substances like morphine, codeine, and heroin, as well as various animal toxins currently under study for their medicinal potential. It's worth noting, that medicinal uses of animal toxins is not a new concept. Compounds similar to snake venom, for example, have found uses as antivirals and painkillers. Future research will reveal the exact mechanism and potential medicinal uses of this spider venom-derived compound.
