When silver ionizes, it donates one electron. A neutral Ag atom has 47 electrons. When it ionizes, it becomes 46. The electronic configuration becomes: [Kr]5s¹4d⁹. Thus, the quantum numbers are:
<em>n = 1,2,3,4,5</em>
<em>l = 0,1,2,3,4 || (0 to n-1)</em>
<em>ml = -4,-3,-2,-1,0,1,2,3,4 || (-l to +l)</em>
<em>ms = +1, -1 </em>
The answer is (2). The electrolytic cell mechanism is to convert the electrical energy to chemical energy. So it need external energy source. And there is a similar one called voltaic cell which will convert the chemical energy to electrical energy.
Answer:
The synthesis of p-chlorobenzenesulfonic acid with the reagents for each step and the structure of the monosubstituted intermediate compound is shown in the drawing below.
Explanation:
Benzenesulfonic acid is obtained from the sulfonation of benzene, using concentrated smoking sulfuric acid.
Chlorination of benzenesulfonic acid with chlorine without catalyst requires a polar solvent, such as acetic acid to obtain the selectivity in the position for and the ortho derivative in a low proportion.
Answer:
distance with a negative value just means that it's going in the opposite direction.
Explanation:
example: -50m East is the just 50m west
DDT stands for Dichlorodiphenyl Trichloroethane.DDT was used in theas a pesticide Second World War to protect the troops and civilians from the spread of malaria and other diseases. <span>Today DDT is used for insect control.
</span>But DDT harms the environment and the human health.
<span>There is an evidence that links DDT with severe declines in bald eagle populations due to thinning eggshells.</span>
So, DDT is dangerous environmental pollutant because it is toxic.
