Answer:

The anode made of the impure copper

The cathode made of pure copper

The electrolyte of copper (II) sulfate CuSO₄ solution

The silver impurities at the anode due to their high tendency of accepting electrons and being a stronger reducing agent than either copper or zinc will remain relatively in place and relatively stable and will not actively take part in the oxidation reaction taking place at the anode

The zinc impurities will be the first element of the three metals to give up electrons and go into the solution as zinc ions due to their high tendency to loan out two electrons and become oxidized into Zn²⁺ ions

The amount of radioactive carbon-14 in a sample is measured using a Geiger counter, which records each disintegration of an atom

sergij07 [2.7K]

Answer:

4121 years

Explanation:

From;

0.693/t1/2 = 2.303/t log No/N

t1/2= half life of the carbon-14

No= count rate of the living tissue

N= count rate of the sample

t = age of the sample

0.693/5730 =2.303/t log (13.5/8.2)

1.21 * 10^-4 = 2.303/t * 0.2165

1.21 * 10^-4 = 0.4986/t

t = 0.4986/1.21 * 10^-4

t = 4121 years

Which of the following answers shows the appropriate organizational order from smallest to largest? In other words, the first st

Naya [18.7K]

The appropriate organizational order from smallest to largest is option b i.e. paired bases, DNA molecule, gene, chromosome, cell, arm, person

Explanation:

The correct sequence of the organization of the smallest to largest is shown as paired bases, DNA molecule, gene, chromosome, cell, arm, person.

Paired bases: The DNA molecule consists of four nucleotide bases, they are adenine, thymine, cytosine and guanine. These are attached to ribose sugar and phosphoric acid forming nucleoside triphosphate. These dNTPs form base pairs with each other in opposite strands by hydrogen bonding. The base pairing occurs between purine and pyrimidine bases as T and A, G and C.

DNA molecule: The dNTPS joined to form specific DNA sequences which encodes the protein in organism.

Gene: It is the sequence of DNA that codes for a particular protein and undergoes transcription and translation.

Chromosome: The chromosome is a thread like structure in which DNA is packaged as genetic information. The gene is a bead like structure present on chromosome.

Cell: It is the basic unit of life in which genetic information is placed in the nucleus.

Arm: It is group pf cells forming tissue and these forms organs, here arm is an organ.

Person: is made up of million of cells. These cells are grouped in tissues and tissues form organs. Group of organs make a human or person.

Hi:) why covalent substances don’t have free moving ions / electrons?

Igoryamba

Answer:

Covalent compounds don't contain ions because they make bonds by sharing electrons. In addition, they don't have any charge carries that are free to move so they can't carry electric current
