Answer:
C. A question and opinions
Explanation:
Answer is 0.7 g
Reason: Given: mass of Fe = 5.60 gWe know that, half life of Fe-53 = t1/2 (Fe-53) = 8.51 min.
Thus, after 25.53 mins, number of half life passed = 25.53/8.51= 3
Now, Amount left after first half life = 5.60g/2 = 2.80 g
Amount left after second half life = 2.80g/2 = 1.40 g
Amount left after third half-life = 1.40g/2 = 0.7g.
Answer:
Troposphere and Atmosphere In this chapter, students learn that water vapor condenses as it moves higher to where the atmosphere is colder. This idea helps students explain why more rain forms over West Ferris than East Ferris.
Explanation:
Answer: d) 16.34 grams
