6.Pure ethanol will irritate the skin and eyes and can cause some sort of poisoning to the body
7.Because Methanol has to first be turned into formaldehyde in the body. Humans have an enzyme called alcohol dehydrogenase, which oxidizes alcohol compounds (adds an oxygen, effectively.) If you drink a beer, the ethanol is converted to acetaldehyde which is a slightly toxic intermediate.
8.Like methanol, ethanol is metabolized by ADH, but the enzyme's affinity for ethanolis 10-20 times higher than it is for methanol. Fomepizole is also metabolized by ADH; however, its use is limited because of high cost and lack of availability. Hemodialysis can easily remove methanol and formic acid.
9. CALL POISON CONTROL IMMEDIATLEY

The carbon atoms in graphite and the carbon atoms in Diamond have different

Stolb23 [73]

It's the actual structure of diamond which made the two different. Diamonds have a tetrahedral structure, and as for graphite, it's not structured in that way. The structures of the two is also the reason why diamond is harder than graphite.

Suppose the gas resulting from the sublimation of 1.00 g carbon dioxide is collected over water at 25.0◦c into a 1.00 l containe

jeyben [28]

Answer:

0.55 atm

Explanation:

First of all, we need to calculate the number of moles corresponding to 1.00 g of carbon dioxide. This is given by

$n=\frac{m}{M_m}$

where

m = 1.00 g is the mass of the gas

Mm = 44.0 g/mol is the molar mass of the gas

Substituting,

$n=\frac{1.00 g}{44.0 g/mol}=0.0227 mol$

Now we can find the pressure of the gas by using the ideal gas law:

$pV=nRT$

where

p is the gas pressure

V = 1.00 L is the volume

n = 0.0227 mol is the number of moles

R = 0.082 L/(atm K mol) is the gas constant

T = 25.0 C + 273 = 298 K is the temperature of the gas

Solving the formula for p, we find

$p=\frac{nRT}{V}=\frac{(0.0227 mol)(0.082 L/(atm K mol))(298 K)}{1.00 L}=0.55 atm$
