There are 8 different elements in this compound
Answer:
Empirical formula : N₂H₈O₄S
Explanation:
Percentage of hydrogen = 6%
Percentage of nitrogen = 21%
Percentage of oxygen = 49 %
Percentage of sulfur = 24 %
Empirical formula = ?
Solution:
Number of gram atoms of H = 6 / 1.01 = 5.9
Number of gram atoms of O = 49 / 16 = 3.1
Number of gram atoms of N = 21 / 14 = 1.5
Number of gram atoms of S = 24 / 32 = 0.75
Atomic ratio:
N : H : O : S
1.5/0.75 : 5.9/0.75 : 3.1/0.75 : 0.75/0.75
2 : 8 : 4 : 1
N:H:O:S = 2 : 8 : 4: 1
Empirical formula : N₂H₈O₄S
A covalent bond is your answer
Answer:
The correct answer is : It is a salt because it is formed by the reaction of an acid and a base.
Explanation:
Sodium chloride is formed from the neutralization reaction between a strong acid (hydrochloric acid) and a strong base (sodium hydroxide):
HCl + NaOH ---> NaCl + H20
By reacting strong acid and base, they neutralize each other resulting in a salt (NaCl) and water.
Corresponds to an exothermic reaction (heat is released).
Some of the class characteristics found on a fired bullet are (1) the caliber of the bullet (diameter), (2) the number of lands and grooves, (3) the twist of the rifling (left or right), and (4) the widths of the land and groove impressions.
