Answer:
the sample undergo 
disintegrations per second.
Explanation:
Given:
The amount of sulphur purchased is 0.671 μCi
To find:
disintegrations per second = ?
Solution:
Some of the conversions are
1 rad = 0.01 Gy
1Gy = 1 j/kg tissue
1 rem = 0.01 Sv
1Sv = 1 j/Kg
Using these conversions,
The decay rate of this sample is calculated as
= disintegrations per second
The reaction that best describes the change of aniline into phenyl isocyanide is
<span>C6H5NH2 + CHCl3 + KOH → C6H5NC + 3KCl + 3H2O
</span>
This is basically a characteristic reaction of the primary amines. <span> from the above reaction, we can see that aniline on carbyl amine reaction gives phenyl iso-cyanide.</span>
Answer:
An example would be ice.
Explanation:
Because ice starts off as a solid and then when it melts from heat turns into a liquid and then if heated can to into a gas.
Answer:
First the chlorophyll (the chemical that makes plants leaves green and traps sunlight)...
Next the sunlight gives the plant energy to start the food-making process.
Then the roots suck nutrients up to the leaves and then the leaves mix carbon dioxide,...
Finally they throw out their waste (oxygen).
