Answer:
temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above.The Earth's magnetic field is generated by the outer core.
Explanation:
Answer: The mass of the sample having 2.1 kg of will be
Explanation: We are given a sample of sodium bicarbonate having mass 2.1 kg
To convert this into nano-grams, we use the following conversions:
1 kg = 1000 grams
and
Converting 2.1 kg to nano-grams using above conversions:
0.06 has one significant figure (unless there are zeros written after it). So I would round the result to 6000. Some teachers prefer at least 2 significant figures though.
