Which is a way that biotechnology has Not helped society? Bacteria is used to grow vaccines in large quantities. Drugs can be de

veloped without the use of animal research. New, stronger bacteria have evolved that are resistant to antibiotics. Diabetics have a steady supply of inexpensive insulin.

Well, you just have to look for the one that does not have any positive/benefit.

1. is not the answer, since vaccines prevent countless people from disease and death. 

2. is not the answer since animal abuse is not okay and the statement shows that science has become more efficient, therefore helping society become more efficient

3. is definitely not a positive effect that biotech has had on society. antibiotic-resistant bacteria endangers everyone. Therefore, this is the answer :)

4. is not the answer because helping people with diabetes be able to afford their medication is very helpful.

How did the surface area of the metal strip expose to the solution affect the
frez [133]

Answer:

See explanation below

Explanation:

In an electrochemical cell, electricity is obtained by the gradual deterioration of the anode.

Hence, surface area of the metal will affect the length of time within which the electrochemical cell works.

The greater the surface area of the metal, the longer the electrochemical cell can function and the greater the quantity of electricity produced, hence the answer above.

How many moles are in a 12.0 g sample of NiC12
Nady [450]

Answer:

0.17 moles

Explanation:

In the elements of the periodic table, the atomic mass = molar mass. <u>Ex:</u> Atomic mass of Carbon is 12.01 amu which means molar mass of Carbon is also 12.01g/mol.

In order to find the # of moles in a 12 g sample of NiC-12, we will need to multiply the number of each atom by its molar mass and then add the masses of both Nickel and C-12 found in the periodic table:

  • Molar Mass of Ni (Nickel): 58.69 g/mol
  • Molar Mass of C (Carbon): 12.01 g/mol

Since there's just one atom of both Carbon and Nickel, we just add up the masses to find the molar mass of the whole compound of NiC-12.

  • 58.69 g/mol of Nickel + 12.01 g/mol of Carbon = 70.7 g/mol of NiC-12

There's 12g of NiC-12, which is less than the molar mass of NiC-12, so the number of moles should be less than 1. In order to find the # of moles in NiC-12, we need to do some dimensional analysis:

  • 12g NiC-12 (1 mol of NiC-12/70.7g NiC-12) = 0.17 mol of NiC-12
  • The grams cancel, leaving us with moles of NiC-12, so the answer is 0.17 moles of NiC-12 in a 12 g sample.

<em>P.S. C-12 or C12 just means that the Carbon atom has an atomic mass of 12amu and a molar mass of 12g/mol, or just regular carbon.</em>
