Explanation:
Answer :
(a) 0.0152
(b) 0.0000000778
(c) 0.000001
(d) 1600.1
Explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example :
5000 is written as
889.9 is written as
In this examples, 5000 and 889.9 are written in the standard notation and and are written in the scientific notation.
(a)
The standard notation is, 0.0152
(b)
The standard notation is, 0.0000000778
(c)
The standard notation is, 0.000001
(d)
The standard notation is, 1600.1
Answer:
1. was the value calculated by the student.
2. was the of ethylamine value calculated by the student.
Explanation:
1.
The value of Aspirin solution = 2.62
Moles of s asprin =
Volume of the solution = 0.600 L
The initial concentration of Aspirin = c =
initially
c 0 0
At equilibrium
(c-x) x x
The expression of dissociation constant :
:
was the value calculated by the student.
2.
The value of ethylamine = 11.87
The initial concentration of ethylamine = c = 0.100 M
initially
c 0 0
At equilibrium
(c-x) x x
The expression of dissociation constant :
:
was the of ethylamine value calculated by the student.
The chemical compound's empirical formula is NS.
The chemical compound's molecular formula is N4S4.
<h3>What does a chemical empirical formula look like?</h3>
- The empirical formula of a compound that gives the proportion (ratios) of the elements in the complex but not the precise number or arrangement of atoms is known as an empirical formula.
- This would be the compound's element to whole number ratio with the lowest value.
<h3>What sort of empirical formula would that be?</h3>
- The chemical structure of glucose is C6H12O6. Every mole of carbon and oxygen is accompanied by two moles of hydrogen.
- Glucose has the empirical formula CH2O.
- Ribose has the chemical formula C5H10O5, which can be simplified to the empirical formula CH2O.

the question you are looking for is
A compound containing only sulfur and nitrogen is 69.6% S by mass; the molar mass is 184 g/mol. What are the empirical and molecular formulas of the compound?
it decreases the density of the object the air bubbles take up space. it increases the volume of the object slightly but the objects weight remains the same, hence the objects density decreases
