Answer:
The correct option (c) "is held together by ionic bonds".
Step-by-step explanation:
Table salt is NaCl. It is a combination of Sodium and Chlorine.
There is 1 valance electron in sodium. Its electronic configuration is 2,8,1
The electronic configuration of Chlorine is 2,8,7. It means that it needs 1 electron so that its octet gets completed.
Na transfers one electron to Cl. It becomes Na⁺. Cl gains one electron From Na. It becomes Cl⁻.
As a resuslt, Na⁺ and Cl⁻ forms. Both Na and Cl are ions. They held together by ionic bonds.
Answer:
AFM = 140
LFM = 70
Step-by-step explanation:
Here, we are to calculate LFM and AFM
Since AFM was bisected, then LFM + AFL is AFM
and also AFL = LFM
Thus;
11x + 4 = 12x -2
12x-11x = 4 + 2
x = 6
AFM = AFL + LFM = 11x + 4 + 12x-2 = 23x + 2
Substitute x = 6
AFM = 23(6) + 2 = 140
LFM = 11x + 4 = 11(6) + 4 = 66 + 4 = 70
Answer:
x + y ≤
3x + 5y ≥ 1100
Step-by-step explanation:
Given:
Seating capacity of theater = 250
Cost of each child ticket = $3
Cost of each adult ticket = $5
Cost per performance = $1100 at least
Find:
System of inequalities
Computation:
Let;
x = Number of children's tickets
y = Number of adult tickets
So
x + y ≤
3x + 5y ≥ 1100
No but , they can be pretty easy sometimes
Two complementary angles must add to 90 degrees, and if you divide 90 into thirds (two parts for the larger angle, one for the smaller), then you get 30 degrees.
If the smaller angle is 30 degrees, then the larger is two times that, which is 60. 60 + 30 = 90, so the larger angle is equal to 60 degrees.
