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:
Osmium is the densest<span> element on earth. It is a hard, weak, pale blue white move metal in the platinum aggregate that is found as a follow component in amalgams, generally in platinum minerals. Osmium is the densest normally happening component, with a thickness of22.59 g/cm3. There is still some open deliberation that Iridium is the denser component as per hypothetical figurings yet starting at now, Osmium has the most noteworthy measured thickness. </span>
Heres the answer to your question
Explanation:
A 57.9 g sample of glass is cooled by 2.70'C how much heat does it release
1560
The answer to this question would be:
<span>2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.
</span>The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.
