Why a person bitten by a snake can not drink alcohol

1 answer:

8 0

Alcoholic liquors are harmful to persons bitten by venomous snakes." The alcohol acts first as a stimulant, speeding up the circulation, quickly distributing the poison through the body. When the effect wears off it becomes a depressant, lowering the victim's resistance,

DESCRIBE THE FINAL TEMPERATURE AFTER DIFFUSION

frez [133]

Answer:

Simple Diffusion

In basic terms, diffusion can be defined as the process by which particles spread out. This is generally from an area where they are high in concentration to an area where they are in a lower concentration. This can be understood by thinking of a pan with onions cooking in it. The smell given off by the onions is very concentrated in the top of the pan, above the cooking onions. The molecules, therefore, move into an area when they are in lower concentration, such as the surrounding air. Eventually, the smell spreads throughout the kitchen or even the entire home.

Mixing Diffusion

If two different gases or liquids are close to each other, the process of diffusion causes them to mix together. Imagine two gases separated by a partition. The free-moving gas molecules bounce off the central partition as they whirl around in their container. If the partition is removed, the gases mix as the molecules move around. This is related to the second law of thermodynamics, which states that in a closed system, all things tend toward entropy. “Entropy,” for this purpose, can simply be defined as disorder; therefore, unmixed particles in a closed system tend to mix, or diffuse.

A Cu2+ solution is prepared by dissolving a 0.4749 g piece of copper wire in acid. The solution is then passed through a Walden

Luda [366]

Answer:

Concentration of $Cr_2O_7^{2-}$ = 0.03101 M

Concentration of $MnO_4^-$ = 0.03721 M

Explanation:

The reduction for $Cr_2O_7^{2-}$ is;

$Cr_2O_7^{2-} + 14 H ^+ _{(aq)} + 6 e^- -----> 2 Cr^{3+} _{(aq)}+7H_2O _{(l)}$

$Cu^+_{(aq)} -----> Cu^{2+} _{(aq)} + 1 e^-$

6 moles of $Cu ^+$ = 1 mole of $Cr_2O_7^{2-}$

number of moles of Cu reacted = $\frac{mass \ of \ Cu \ wire }{ molecular weigh tof \ Cu wire }$

number of moles of Cu reacted = $\frac{0.4749}{63.55}$

number of moles of Cu reacted = 0.00747 mole

number of moles of $Cr_2O_7^{2-}$ reacted = $\frac{0.00747}{6}$

number of moles of $Cr_2O_7^{2-}$ reacted = 0.001245 mole

Concentration of $Cr_2O_7^{2-}$ = $\frac{number \ of moles }{Volume}$

Given that the volume = 40.15 mL = $40.15 *10^{-3}$ ; we have:

Concentration of $Cr_2O_7^{2-}$ = $\frac{0.001245}{40.15*10^{-3}}$

Concentration of $Cr_2O_7^{2-}$ = 0.03101 M

The reduction for $MnO_4^-$ is;

$MnO_4^- + 8H^+ + 5 e^- -----> Mn^{2+} + 4H_2O$

$Cu^+_{(aq)} -----> Cu^{2+} _{(aq)} + 1 e^-$

5 moles of $Cu ^+$ = 1 mole of $Cr_2O_7^{2-}$

number of moles of Cu reacted = $\frac{mass \ of \ Cu \ wire }{ molecular weigh tof \ Cu wire }$

number of moles of Cu reacted = $\frac{0.4749}{63.55}$

number of moles of Cu reacted = 0.00747 mole

number of moles of $MnO_4^-$ reacted = $\frac{0.00747}{5}$

number of moles of $MnO_4^-$ reacted = 0.001494 mole

Concentration of $MnO_4^-$ = $\frac{number \ of moles }{Volume}$

Given that the volume = 40.15 mL = $40.15 *10^{-3}$ ; we have:

Concentration of $MnO_4^-$ = $\frac{0.001494 }{40.15*10^{-3}}$

Concentration of $MnO_4^-$ = 0.03721 M

Dmitry_Shevchenko [17]

Answer:

Increase the concentration of the solution

Explanation:

Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration
