Answer:
The formula of the molecule given above can also be written as C4H10.
If you count all the carbon atoms you will discover, they are four while that of hydrogen is 10.Thus, the name of the compound is ISOBUTANE [I -BUTANE]; it is also called 2 - methyl propane. Isobutane is used majorly as petrol additive in refineries; it is used in the production of isooctane, which is a octane gasoline component that enhances the octane rating and anti-knock properties of gasoline.
Explanation:
They should throw it away and use a different one
Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
It's mean the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.
Answer:
9.57 mol.
Explanation:
<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>
<em />
<em>M = (no. of moles of solute)/(V of the solution (L)).</em>
<em></em>
∴ M = (no. of moles of sucrose)/(V of the solution (L)).
1.1 M = (no. of moles of sucrose)/(8.7 L).
<em>∴ no. of moles of sucrose = (1.1 M)(8.7 L) = 9.57 mol.</em>
