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.
Answer:
Number of times bond interest charges were earned = 5.44
Explanation:
Given data,
Bond Interest Rate = 6%
Bond Amount = $1200000
Net Income before Income Tax = $320000
Bond Interest charges Earned
:
= Bond Value × Interest Rate
= $1,200,000 × 6%
= $72,000
Net Income before Interest
:
= Net Income Income Before Interest + Interest
= $320,000 + $72,000
= $392,000
Number of times bond interest charges were earned
:
= Net Income before Interest and taxes ÷ Interest charges
= (392,000 ÷ 72,000
)
= 5.4444
Number of times bond interest charges were earned = 5.44
Answer:
a. $2,634.36
$1,481.11
Explanation:
a. Ryan can claim the direct costs of the trip being gasoline and oil. He can therefore claim the $1,920 he paid for gasoline.
In addition, some of the indirect costs can be claimed as well such as depreciation. The claim is calculated as:
= Depreciation amount * Business miles / Total miles driven
= 3,900 * 3,700 / 20,200
= $714.36
Total deduction = 1,920 + 714.36
= $2,634.36
b. Ryan needs to be able to prove that the cost he is claiming are indeed business expenses. Total deductibles are:
= (3,900 * 1,400/ 20,200) + (1,400/2,220 * 1,920)
= $1,481.11

Consumer surplus is the difference between the total amount a consumer is willing to pay for an item and what they actually pay. The total amount that Natasha, Nelson and Nikolai are willing to pay for the flashlight is $34, the amount they do pay is $20. So, the total consumer surplus for them is $14.
