Answer:
if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away.
Explanation:
Explanation:
Formula to calculate how many particles are left is as follows.
N = 
where, 
= number of initial particles
l = number of half lives
As it is given that number of initial particles is 
and number of half-lives is 3.
Hence, putting the given values into the above equation as follows.
N = 
= 
= 
or, 
Thus, we can conclude that particles of radioactive nuclei remain in the given sample.
In five hours we've gone through 5 half lives so the answer is:
particles
Answer:
This stiffening process, called Rigor Mortis, has a roughly known time of occurrence and can therefore be used to estimate time of death. In general: If the body feels warm and no rigor is present, death occurred under 3 hours before. If the body feels warm and stiff, death occurred 3-8 hours earlier.
By use of combined gas law
P2= T2P1V1/V2
v1=5L
P1=540 torr
T1=25+273=298k
V2=15 L
T2=32+273=305 k
P2 is therefore=( 305k x 540 torr x5 L) /( 15L x 298)= 184.23 torr
The IUPAC name of the above mentioned compound is "2-Chloro-4,4-dimethylpentane"
<u>Exaplanation:</u>
- Since the above organic compound is an compound with only one saturated bond, It can be considered as a single bond compound, and hence we can conclude that as alkane.
- It also has 5 carbon atoms, so it is termed as pentane.
- From right to left we have to number the atoms, and 2 nd carbon atom contain Cl atom so it is termed as 2-Chloro and in the 4th position carbon atom contains 2 methyl groups, so it is termed as, 2-Chloro-4,4-dimethylpentane.
