The next layer is about 30 million years older and contains plant fossils in its mixed shale, limestone, and sandstone rock layers. The third to last layer is full of brachiopods, trilobites, and trilobite tunnels. You believe it is the oldest layer above surface in the Grand Canyon.
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete
<span>This is an example of diffusion. The nitrous oxide is moving from an area of higher concentration, down the gradient into the cell, which has a lower concentration. Since the cell doesn't have as much N2O as the surrounding environment, the gas will move inside the cell as a way of attaining equilibrium.</span>
About 46.1 pounds of apple would be needed per day of the trip.
I managed to extract the complete scenario from the attached image.
The trip is made up of 4 men and 3 women, making a total of 7 people.
Everyone has become accustomed to 1500 calories per day.
The total calories needed per day for 7 persons = 1500 x 7
= 10,500 calories
189 g of apple has only 95 calories, what g of apple will produce 10,500 calories?
= 10,500 x 189/95 = 20,889.67 g of apple
From conversion:
1 g = 0.00220462 pounds
20,889.67 g = 20,889.67 x 0.00220462
= 46.1 pounds of apple
