There are 31.1 grams (g) in 1 troy ounce (ozt). How many ozt of gold are extracted from 1 short ton of average Nevada ore
devlian [24]

This problem is providing us with the mass equivalent to one troy ounce. Thus, the troy ounces of gold in one short ton of average Nevada ore is required and found to be the 0.103 otz according to the following dimensional analysis.

<h3>Dimensional analysis</h3>

In chemistry, a raft of problems do not always provide an equation in order to be solved yet dimensional analysis can be applied, so as to obtain the desired amount in the required units.

Thus, since this problem asks for try ounces in an average Nevada ore,  which has 3.2 grams of gold per short ton of ore, one can solve the following setup in order to obtain the required answer in otz:

\frac{3.2gAu}{1short-ton}*1short-ton*\frac{1otz}{31.1g} \\

Where the short tons are cancelled out as well as the grams, in order to obtain:

0.103 otz

One serving of peanut butter contains 5.0 g of carbohydrate, 12 g of fat, and 6.0 g of
larisa [96]

The serving of peanut butter contains 117kcal

<h3>Calculation of calories of food Nutrients</h3>

1 gram of both carbohydrate and protein contains 4 (kcal)

1 gram of fat contains 9 (kcal)

But peanut butter contains 5g of fat. The kilocalories of fat present is;

1 g = 9 kcal

5g = F

F = 5×9

F = 45 kcal

The kilocalories of carbohydrates present is;

1g = 4kcal

12g = C

C= 12×4

C = 48kcal

The kilocalories of proteins present is;

1g = 4kcal

6 g = P

P = 4× 6

P = 24 kcal

Therefore, the total kilocalories of the peanut = 45 + 48 + 24 = 117kcal

List down the observations made by Rutherford during the gold foil experiment.
Travka [436]

Answer:

1) The volume occupied by an atom is composed of mainly empty space

2) Atoms have a very small, relatively dense, central nucleus that is positively charged

3) The region around the nucleus of an atom are orbited by negatively charged electrons in a the same fashion planets orbit around the Sun.

Explanation:

The selection of gold for the gold foil experiment was due to its ability to be rolled into extremely thin sheets such that it was expected for alpha particle to perforate or pass through the foil.
