Explanation:
# moles that exist in 1.9 X 10 23 =
= # of atoms/# of Avogadro 's num
= 1.9 X 10 23 / 6.02x10 23
= 0.266 mole of Pb
now we calculate the mass
mass of lead = # mol x m.wt
= 0.266 X 106.4
= 28.30 gram

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.
Final answer:
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.
Explanation:
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.

Explanation:
Starting moles of ethanol acid = 0.020 mol
At the equilibrium 50 % of the ethanol acid molecules reacted
∴ Moles of ethanol acid reacted = 0.020 mol * 50 %/100 %
= 0.010 mol
Moles of ethanol acid remain = 0.020 mol + 0.010 mol = 0.010 mol
Moles of the product gas formed are calculated as
0.010 mol CH3COOH * 1 mol / 2 mol CH3COOH
= 0.005 mol
Therefore at the equilibrium total moles of gas present in the vessel are 0.010 mol CH3COOH and 0.005 mol
That is total gas moles at equilibrium = 0.010 mol + 0.005 mol = 0.015 mol
Now Calculate the pressure :
0.020 mol gas has pressure of 0.74 atm therefore at the same condition what will be the pressure exerted by 0.015 mol gas
P1/n1 = P2/n2
P2 = P1*n2 / n1
= 0.74 atm * 0.015 mol / 0.020 mol
= 0.555 atm

In one experiment, you do not have the metal oxalate productas dry as possible. This might affect the pyrolysis procedure by maybe thewater will react with the compound at very high temp; the initial weight of thesample is already incorrect that might cause error in the further calculations.
Answer:
The process would not be attained completely.
Explanation:
Hello,
In chemical reactions, pyrolysis is understood as a thermochemical decomposition or breaking of organic chains at very high temperatures and under the absence of halogens and oxygen. In this case, as a metal oxalate is the organic chain, when it is a product and is not dry as possible, the reaction would not be attained to completion as the water will limit the conversion and the reaction extent.
Best regards.
