Answer:
Explanation:
Group Most Likely Ionic Charge Number of Valence Electrons
I +1 1
II +2 2
III +3 3
IV +4 or -4 4
V -3 5
VI -2 6
VII -1 7
VIII 0 8
For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)
Answer:
B. only one copy of the field in memory
Explanation:
A static method is sort of a description of a class but is not part of the objects that it generates. Crucial: A program may perform a static method without constructing an object first! All other functions (those not static) only occur when they're member of an object. Thus it is necessary to build an object before they could be executed.
Therefore, when an static field is declared static, there will be:
B. only one copy of the field in memory
Answer:
35.94 g of NaCl
Explanation:
First write a balanced chemical reaction.
2Na + Cl₂ --> 2NaCl
(Note that the Cl has a subscript of 2 because it's diatomic)
Then, set up an basic stoichiometry equation using one of the given masses of the reactants. I chose chloride.
The masses were acquired from the periodic table. (compound's mass requires the addition of individual element's masses) Also, the number of moles per reactant or product is based on the coefficient from the chemical reaction. I can't show this, but note that the units do cancel out so all that's left is grams of sodium chloride, which is what we were looking for.
