(2.32g/cm³) x (1kg/1000g)x(1 000 000 cm³/1m³) = 2320 kg/m³
1 ml= 1 cm³
Answer:
Alloys and Composites
Explanation:
<u>Drill bits are made of alloys</u> because alloys are very much resistant to corrosion and are created when one or multiple metals are mixed with other elements that are non-metallic in nature. Due to their greater strength, they are used in the power drills in order to create borehole drills at the mining site. Borehole drilling is commonly done in order to understand the sub-surface strata before mining.
<u>The bodies along with the handles of power drills are constructed of composite insulators</u> because within the composites there is the absence of free electrons that has the ability to flow and produce electricity. So they are considered to be used as a good insulator.
Order each of the following sets of five atoms and ions according to decreasing size. "1" largest and "5" smallest.
<span>O </span>
<span>S^2- </span>
<span>O^2- </span>
<span>Te^2- </span>
<span>Se^2- </span>
<span>I know the more negative the ion, the larger the element. but i dont understand how to do it when they all have the same charge, and an element with no charge. </span>
Explanation:
In the given molecule of 5-isopropyl-2-methyl-3-nonene their are nine carbon atom attached in straight chain.
- 3-nonene means that double bond is between the third carbon and forth carbon atom.
- Isopropyl group
on the fifth carbon atom in the chain
- Methyl group
on second carbon atom in the chain.
Th structure of the given organic molecule is attached as an image.
