Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g

Is wood heavier than paper
Explanation:
This is the only question that can have a definite answer and not an opinionated response
The geosphere consists of the solid Earth and the atmosphere consists of the gaseous components in the air. Thus, the answer is C.
Answer: The ATP(Adenosine Triphosphate) that will be generated if one pyruvate molecule is carried through cellular respiration is 36.
Explanation: Pyruvate is formed through glycolysis cycle which breaks down glucose. The pyruvate is used in aerobic cellular respiration via the TCA cycle yielding 2 ATPs and the electron transport system yielding 34 ATPs. That makes it up to a total of 36 ATPs.
