Answer:
71 Ga has a naturally abundance of 36%
Explanation:
Step 1: Given data
Gallium has 2 naturally occurring isotopes: this means the abundance of the 2 isotopes together is 100 %. The atomic weight of Ga is 69.72 amu. This is the average of all the isotopes.
Since the average mass of 69.72 is closer to the mass of 69 Ga, this means 69 Ga will be more present than 71 Ga
Percentage 69 Ga> Percentage 71 Ga
<u>Step 2:</u> Calculate the abundance %
⇒Percentage of 71 Ga = X %
⇒Percentage of 69 Ga = 100 % - X %
The mass balance equation will be:
100*69.72 = x * 71 + (100 - x)*69
6972 = 71x + 6900 -69x
72 = 2x
x = 36 %
71 Ga has a naturally abundance of 36%
69 Ga has a naturally abundance of 64%
Answer:
Explanation:
Potential energy is the energy possessed by an object due to its position. For example, when the ball starts to move from its resting position then the ball gains kinetic energy. Thus, as gravity makes an object fall down toward the ground, potential energy becomes kinetic energy.
Answer:
Explosive, Propellant and Semiconductor
Explanation:
Biochemical sediment like black shale (carbonaceous shale) and lignite and coal will form from the weathering ie reduction and decomposition of plant organic matter and thus store it in the geosphere, Also, carbon is naturally sequestered in the formation of carbonate rocks like limestone by combination of the carbon dioxide in the oceans (which may be in the form of carbonic acid) with metals to form calcium and magnesium carbonate compounds.
