Energy and the nature of the current
Answer:
12 mol O2
Explanation:
8 mol KCl (3 mol O2/ 2 mol KCl) =12 mol O2
Answer:
When a cation forms, more electrons are transferred to it
Explanation:
Ions can either be cations (positively charged species) or anions (negatively charged species).
Cations are produced when atoms, typically metal atoms, lose their valence electrons to become positively charged.
Anions are produced when nonmetal atoms gain electrons to become negatively charged.
These definitions already eliminate the majority of choices: cations are positively charged ions. Anions are common among nonmetals.
Thinking about nomenclature, charges are represented by a superscript of a number with either a plus (for positive charges) or a minus (for negative charges).
It is false, however, that when a cation forms, electrons are transferred to it. In reality, cations lose electrons rather than gain.
Answer:
5.46x
Explanation:
just move the decimal however many places to the left until there is only one digit to the left of it and then square the ten by that number
Answer:
Transition metal
Explanation:
The elements in the middle are called Transition metal and the have similarity in the atomic structure resulting in similar properties, for example they are less reactive than the alcaline earth metals
