Furkat [3]

Answer:

(1) breaking a pencil (2) rusting of iron

Explanation:

breaking a pencil does not alter the chemical properties of the pencil, it merely breaks it into 2 while the rusting of iron is changing the properties chemically because the iron is oxidizing and reacting with the water and oxygen in the atmosphere

Two molecules that can cross a lipid bilayer without help from membrane proteins are o2 and co2. what property allows this to oc

Dennis_Churaev [7]

Two molecules that can cross a lipid bilayer without help from membrane proteins are oxygen and carbon dioxide. The property that allows this to happen is that both oxygen and carbon dioxide molecules are nonpolar which means that they can pass easily through the hydrophobic part of the membrane. The lipid bilayer is present in all cell membranes. It consists of two layers of the fat cells which are arranged into two sheets. It functions as a barrier which marks the boundaries of the cell. The inner part of a lipid bilayer is nonpolar since it is composed of the hydrophobic end of the phospholopids.

Mila [183]

Answer:

Explanation:

Half life of Nobelium-253 is 97 seconds . That means after every 97 seconds half of the Nobelium amount will be disintegrated .

Time taken in bringing the sample to laboratory = 291 seconds

291 second = 291 / 97 half life

n = 3

N = $N_0 (\frac{1}{2})^n$

N₀ is original mass , N is mass after n number of half life.

N = 5 mg x $(\frac{1}{2})^3$

= .625 mg

Only 0.625 mg of Nobelium-253 will be left .

g what would happen to the solubility of a gas in a solution if the pressure above the solution is increased

qaws [65]

Answer: The solubility of gas increases in a solution if the pressure above the solution is increased

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C=K_H\times p$

where,

C = solubility

$K_H$ = Henry's constant

p = partial pressure

As the solubility is directly proportional to the pressure, thus increasing the pressure increases the solubility.
