Answer:
The first 20 elements of the periodic table :
1.H —Hydrogen
2.He—Helium
3.Li—Lithium
4.Be—Beryllium
5.B—Boron
6.C—Carbon
7.N—Nitrogen
8.O—Oxygen
9.F—Fluorine
10.Ne—Neon
11.Na—Sodium
12.Mg—Magnesium
13.Al—Aluminum
14.Si—Silicon
15.P—Phosphorus
16.S—Sulfur
17.Cl—Chlorine
18.Ar—Argon
19.K—Potassium
20.Ca—Calcium
The valency of first 20 elements is as follows :-
1. Hydrogen (H) = 1
2. Helium (He) = 0
3. Lithium (Li) = 1
4. Beryllium (Be) = 2
5. Boron (B) = 3
6. Carbon (C) = 4
7. Nitrogen (N) = 3
8. Oxygen (O) = 2
9. Fluorine (F) =1
10. Neon (Ne) = 0
11. Sodium (Na) = 1
12. Magnesium (Mg) = 2
13. Aluminium (Al) = 3
14. Silicon (Si) = 4
15. Phosphorus (P) = 3, 5
16. Sulphur (S) = 2
17. Chlorine (Cl) = 1
18. Argon (Ar) = 0
19. Potassium (K) = 1
20. Calcium (Ca) = 2
Explanation:
First 20 elements in the periodic table start with H and end with Ca. The quickest way to remember the number of valence electrons is to form a relationship with the number of the group the element is located in.
A. it makes sence out of all. im trully sorry if its wrong.
Answer:
Allocated MOH= $92,500
Explanation:
<u>First, we need to calculate the predetermined overhead rate:</u>
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 1,850,000 / 20,000
Predetermined manufacturing overhead rate= $92.5 per hour
<u>Now, we can allocate overhead to Job B12:</u>
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 92.5*1,000
Allocated MOH= $92,500
Answer:
B.
Explanation:
Social Security is Payroll Tax.
Answer:
Results are below.
Explanation:
<u>To calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
a) i= 0.04 annually compounded
n= 5
PV= $625
FV= 625*(1.04^5)
FV= $760.41
b) i= 0.04/2 = 0.02 semiannually compounded
n= 5*2= 10
PV= $625
FV= 625*(1.02^10)
FV= $761.87
c) i= 0.04/4 = 0.01 quarterly compounded
n= 5*4= 20
PV= $625
FV= 625*(1.01^20)
FV= $762.62
d) i= 0.04/12 = 0.0033 monthly compounded
n= 5*12= 60
PV= $625
FV= 625*(1.003333^60)
FV= $763.11
