Answer:
semipermeability
Explanation:
partially but not freely or wholly permeable specifically : permeable to some usually small molecules but not to other usually larger particles a semipermeable membrane.
Answer:
Two of the three salts are soluble.
One of the three salts is soluble.
Explanation:
<em>One or two of the three salts would be soluble in water depending on if the water is cold or hot.</em>
<u>According to the solubility rules of chloride salts, all chlorides are soluble in cold water except for those of silver (Ag), lead (Pb), and mercury (I) (Hg). </u>
This thus means that both AgCl and
would be insoluble in cold water while LiCl would be soluble.
is, however soluble in hot water.
Hence, in cold water, one of the three salts (LiCl) would be soluble, while in hot water, two of the three salts (LiCl and
) would be soluble.
Answer:
127.15 °C
Explanation:
<em>Gay-Lussac's law</em> states that the pressure of a given mass of gas directly proportional to the absolute temperature of the gas at constant volume.
Mathematically,
P₁ / T₁ = P₂ / T₂ -----(1)
Data Given:
Initial Pressure = P₁ = 1 atm (assumed)
Initial Temperature = T₁ = -73°C = 200.15 K
Final Pressure = P₂ = 2 atm (<em><u>doubled</u></em>)
Final Temperature = T₂ = <u>????</u>
Solving equation 1 for T₂,
T₂ = P₂ × T₁ / P₁
Putting these values;
T₂ = 2 atm × 200.15 K / 1 atm
T₂ = 400.3 K
Or,
T₂ = 127.15 °C
Conclusion:
By doubling the pressure results in increase in temperature.
I will say 3 is wrong because the time of day doesn't matter.But what really matters is 1,2,4 we just need to figure which one is correct.
1.The Wife's blood
Real blood will smell bad and with the time it will turn the color red to a dark-ish color red with brown.To see if it is real you have to see if the blood is a dark brown with red if it's not then it's a fake.
2.The type of Gun
You have to feel if it's a fake it might be plastic or another toy material.The gun has to feel like metal.
So the answer might be 1 or 2
Hope this helps :)
