Answer: 5
Explanation: this is because the energy level of the emitted of absorbed photon increases as the number of electron shell decreases, thereby making the inner shell have higher energy than other shells
Answer:
24 a 2.85
Explanation:
HCl is a powerful acid so it completely ioniz in water
Answer:
collide less often and with less force
Answer: AZ is the insoluble choice.
Explanation:
Z is an anion of a weak electronegative element. Hence, it bounds lightly with the highly electropositive cation A to form AZ.
AZ is not as ionic as AX, AY, BX, BY and BZ, so it is insoluble in water and yields precipitate on reaction with the salt of a weaker metal.
Answer:
<em>By</em><em> </em><em>Bayer</em><em> </em><em>process</em><em>.</em>
Explanation:
<em>In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process.</em>
