Explanation:
The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat.
1 gal ---------- 3785.41 cm³
2.9 gal --------- ??
2.9 x 3785.41 / 1 => 10977.689 cm³
Answer:
5.06 M LiCl
Explanation:
To find the new molarity of the solution, you need to (1) find the amount of moles LiCl (via the molarity equation using the original molarity and volume) and then (2) calculate the new molarity (via the molarity equation using the new volume and old moles). The final answer should have 3 sig figs to match the given values.
Molarity (M) = moles / volume (L)
<u>Step (1)</u>
381 mL / 1,000 = 0.381 L
Molarity = moles / volume
9.96 M = moles / 0.381 L
(9.96 M) x (0.381 L) = moles
3.79 = moles
<u>Step (2)</u>
750 mL / 1,000 = 0.750 L
Molarity = moles / volume
Molarity = 3.79 moles / 0.750 L
Molarity = 5.06 M
Answer:
The two most important aspects of precision are reliability and validity. Reliability refers to the reproducibility of a measurement. You quantify reliability simply by taking several measurements on the same subjects!
Answer:
D.ionic interaction is a strong interaction
