The mass is the protons+neutrons and the atomic number is just how many protons there are
The answer is (4) amino acid. This molecule has one carboxyl and one amidogen linked at the same carbon atom. This is the property of amino acid. So this is an amino acid.
Answer:
cccfffffff
Explanation:
Integrated rate law for second order kinetics is:
Where, is the final initial concentration
is the initial concentration = 0.355 M
k is the rate constant = 0.540 (Ms)⁻¹
t is the time = 15.9 seconds
Applying the values in the above expression as:-
<u>11.4 M of will be left after 15.9 seconds have passed.</u>
Affordability and climate
Explanation:
1) Initial mass of the Cesium-137== 180 mg
Mass of Cesium after time t = N
Formula used :
Half life of the cesium-137 = = initial mass of isotope
N = mass of the parent isotope left after the time, (t)
= half life of the isotope
= rate constant
Now put all the given values in this formula, we get
Mass that remains after t years.
Therefore, the parent isotope remain after one half life will be, 100 grams.
2)
t = 70 years
N = 35.73 mg
35.73 mg of cesium-137 will remain after 70 years.
3)
N = 1 mg
t = ?
t = 224.80 years ≈ 225 years
After 225 years only 1 mg of cesium-137 will remain.
