WHILE ARRANGING THE ELEMENTS, NEWLAND OBSERVED THAT ORDER HE SET WERE LIKE NOTES REPRESENTED AS THE SIGNS,THAT IS, EVERY FIRST NOTE IS EQUAL TO THE EIGHT ELEMENT, BUT HE COULD FIND ONLY 58 ELEMENTS THAT WERE CORRECTLY ORDERED IN HIS TABLE
Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..
Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
Answer:
Asexual reproduction
Explanation:
Cells are able to re produce themselves without other cells needed. If cells need others to make more then how would that work and plus we wouldn't have the theory of cells existing.
Answer:
12.19 hours prior to discovery was the corpse placed in the desert.
Explanation:
Heat required for fly eggs to develop into first instar larvae = ![Exposure\,time\times temperature](https://tex.z-dn.net/?f=Exposure%5C%2Ctime%5Ctimes%20temperature)
From the given,
Exposure time = 16 hrs
Temperature = 27 C
![=16\times 27 = 427.2^{o}C](https://tex.z-dn.net/?f=%3D16%5Ctimes%2027%20%3D%20427.2%5E%7Bo%7DC)
The day time exposed hours is 10 hrs.-(7.00am-5.00pm)
![=10\times 37.8 = 378^{o}C](https://tex.z-dn.net/?f=%3D10%5Ctimes%2037.8%20%3D%20378%5E%7Bo%7DC)
So, the extra heat = 427.2-378= 49.2
The addition heat divided by average temperature.
Average temperature = 22.4 C
![=\frac{49.2}{22.4}= 2.19 hrs](https://tex.z-dn.net/?f=%3D%5Cfrac%7B49.2%7D%7B22.4%7D%3D%202.19%20hrs)
So, the total time exposed is night time hours to day time hours.
= 10+2.19 = 12.19 hrs.
Therefore, 12.19 hours prior to discovery was the corpse placed in the desert.
