Density is the ratio of mass to the volume.
The mathematical expression is given as:
Now, density of isooctane = 
Volume = 
Since, 1 gallon = 3.78 L
So, 3.8 gal = 
= 
As, 1 L = 1000 mL
Therefore, = 
Volume in mL = 
Put the values,
= 
Hence, mass of 3.8 gal of the gasoline is .
Answer:
A skater moving downhill at increasing speed
Explanation:
- A push or pul on object called force .It is of two types.
- Balanced force
- Unbalanced force
Answer:
Decrease
Explanation:
Since the speed in which the gas molecules are faster as they are heated, they fly around in the container and logically, it is harder to insert a moving object into water than something more stationary or slower.
Cytokinesis ensures that one nucleus ends up in daughter cells during cell division
The compound nitrogen have most positive oxidation state is NO₂. The correct option is b.
<h3>What is oxidation state?</h3>
The total number of electrons gained or lost by an atom in order to form a chemical bond with another atom.
The charge on an ion is equal to the sum of the oxidation states of all the atoms in the ion. A substance's more electronegative elements are given a negative oxidation state.
A positive oxidation state is assigned to the less electronegative element.
Thus, the correct option is b, NO₂.
