Answer:
2
Explanation:
Devising a repellent would by far be the most successful scenerio. The synthetic compound N,N-diethyl-meta-toluamide (DEET) is a good example of this repellant.
Answer:
Explanation:
The equation of the reaction of Silver sulfide with aluminum in the presence of sodium bicarbonate (NaHCO₃)
3 Ag₂S(aq) + 2 Al(s) → 6 Ag (s) + Al₂S₃(aq)
Answer : The atomic mass of chlorine is, 36.723 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
Mass of 35-Cl isotope = 35 amu
Percentage abundance of 35-Cl isotope = 13.85 %
Fractional abundance of 35-Cl isotope = 0.1385
Mass of 37-Cl isotope = 37 amu
Percentage abundance of 37-Cl isotope = 86.15 %
Fractional abundance of 37-Cl isotope = 0.8615
Now put all the given values in above formula, we get:
Therefore, the atomic mass of chlorine is, 36.723 amu
Answer:
<em>Since the 3s if now full we'll move to the 3p where we'll place the remaining five electrons. Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.</em>
