Answer:
only a small percentage of mutations cause genetic disorders most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene
Explanation:
<u>Answer:</u> The solubility of ethylene gas in water is ![9.16\times 10^{-2}g/L](https://tex.z-dn.net/?f=9.16%5Ctimes%2010%5E%7B-2%7Dg%2FL)
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
![C_{C_2H_4}=K_H\times p_{C_2H_4}](https://tex.z-dn.net/?f=C_%7BC_2H_4%7D%3DK_H%5Ctimes%20p_%7BC_2H_4%7D)
where,
= Henry's constant = ![4.78\times 10^{-3}mol/L.atm](https://tex.z-dn.net/?f=4.78%5Ctimes%2010%5E%7B-3%7Dmol%2FL.atm)
= molar solubility of ethylene gas = ?
= partial pressure of ethylene gas = 0.684 atm
Putting values in above equation, we get:
![C_{C_2H_4}=4.78\times 10^{-3}mol/L.atm\times 0.684atm\\\\C_{C_2H_4}=3.27\times 10^{-3}mol/L](https://tex.z-dn.net/?f=C_%7BC_2H_4%7D%3D4.78%5Ctimes%2010%5E%7B-3%7Dmol%2FL.atm%5Ctimes%200.684atm%5C%5C%5C%5CC_%7BC_2H_4%7D%3D3.27%5Ctimes%2010%5E%7B-3%7Dmol%2FL)
Converting this into grams per liter, by multiplying with the molar mass of ethylene:
Molar mass of ethylene gas = 28 g/mol
So, ![C_{C_2H_6}=3.27\times 10^{-3}mol/L\times 28g/mol=9.16\times 10^{-2}g/L](https://tex.z-dn.net/?f=C_%7BC_2H_6%7D%3D3.27%5Ctimes%2010%5E%7B-3%7Dmol%2FL%5Ctimes%2028g%2Fmol%3D9.16%5Ctimes%2010%5E%7B-2%7Dg%2FL)
Hence, the solubility of ethylene gas in water is ![9.16\times 10^{-2}g/L](https://tex.z-dn.net/?f=9.16%5Ctimes%2010%5E%7B-2%7Dg%2FL)
Answer:
Cooling lowers the rate of the chemical reaction in the batteries.
Explanation:
When a battery is not in use and it may undergo some chemical changes which leads to decrease in its life (shelf life).
For example in case of Zinc battery, the zinc undergoes reaction with ammonia which deteriorate the cell or battery.
Now if we keep the battery in a cool place like refrigerator, the rate of chemical reaction will decrease (the rate of reaction generally decreases with decrease in temperature). Thus the battery stay fresh longer.
Answer:
They will be attracted with the uncharged object. ... The negative attracts positive ions of the uncharged object and the positive does the opposite one.
