Answer:
Molecules make scents. Aromatic ones (That is, containing rings of carbon atoms with delocalised electrons). Some unpleasant smells are due to hydrogen and sulphur groups.
Explanation:
The answer for the following problem is mentioned below.
- <em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Explanation:
Force:
The push or pull on an object with mass that cause change in the velocity
It is a vector quantity.
The formula to calculate the force is:
F = m × a
Given:
Force (F) = -136 N
acceleration (a) = -9.6 m/s^2
To calculate:
mass of the object (m)
We know that,
<em>F = m × a</em>
where,
F represents the force of the object
m represents mass of an object
a is acceleration of an object
From the equation;
-136 = m × -9.6
m = 
m = 14.16 grams
<em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Answer:
1.76 * 6.02*10^23 = 1.05952*10^24
1.05952*2 = 2.11904 *10^24 oxygen and 1.05952*10^24 sulfur atoms
Density is found by dividing mass over volume:
d=M/V. In this problem, we know the density, and the mass. Solve the general equation for volume, then enter the values from the problem and evaluate:
d=m/v [multiply v to both sides, then divide d from both sides]
v=m/d
v=83.8g/(2.33g/cm³)
v=35.965 cm³
v=36.0 cm³ to three significant figures (since your given information only has 3 sig figs)
Answer:
dinitrogen pentoxide
Explanation:
Based on the research, dinitrogen pentoxide is a chemical compound containing only nitrogen and oxygen which is both nonmetal. When two nonmetals or two negatively charged atoms try to form bonds, they always form covalent bonds. Hence, Dinitrogen Pentoxide is not ionic - it is covalent.
