A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.
Hello!
To know how many moles of iron can be recovered from 100 kg of Fe₃O₄ we'll need to use the
molar mass of Fe₃O₄ and apply the conversion factor to go from kg of Fe₃O₄ to moles of Fe in the following way:
So, theoretically, one could recover
1192,68 moles of Fe from 100 kg of Fe₃O₄
Have a nice day!
Answer:
5.56 moles H₂O
Explanation:
moles = mass of substance / formula weight of substance
∴moles H₂O = 100 grams / 18 grams/mole = 5.56 moles H₂O
Answer:
The correct answer is - B) gaining electrons will fill their octet faster than losing them.
Explanation:
Halogens are located in the 17 th group in the periodic table and have elements like fluorine, chlorine bromine and others. All these elements are nonmetals and have similar electron numbers in their octet.
That is the reason of their high effective nuclear charge as they are electronegative and therefore readily get electrons to become anion with other elemnts in chemical reaction. These elements make anion formed when a nonmetal atom gains one or more electrons.
