Well, I'm not completely sure, but, I'm going to try and help you: First, you would need to observe the machine, which, would represent the first step. Secondly, you would have to ask yourself a question, when the ball shoots out, which way are you going to hit it? Next, you'd have to hypothesize, which way the ball will come, which way will give you the most points. etc, etc. Then, you'd make a prediction based on your hypothesis, predict the direction that will give you the most points, and which way the ball will fall. Now, when the ball shoots out, you'd gave to test your prediction, then you'd see if your hypothesis was correct. Lastly, you would iterate, and, come up with new hypotheses, and, predictions, for when you play on round two, this would, also, help you get better at the game, just as, when you perform other scientific experiments, you would have a better idea on what would happen during them. I hope this helps!!!

Grams in 1.083e+24<br> Molecules Na BR<br><br><br> Please help explain why
adoni [48]

Answer:

185 gms o NaBr

Explanation:

Na Br  mole weight = 22.989 +79.904 = <u>102.893  gm/mole</u>

1.083 x 10^24  molecules / 6.022 x 10^23 molecules / mole = <u>1.798 moles</u>

102.893  *  1.798 = 185 gms

The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2). How many kilograms of chalcopyrite must be mined to
diamong [38]

Answer:

0.693kg of CuFeS2 is needed to produce 240 grams of Cu.

Explanation:

In 1 mole of CuFeS2 is associated 1 mole of Cu.

Molar mass of CuFeS2 = 183.5 g/mol

Molar mass of Cu = 63.5g/mol

No of moles of copper present in 240g of chalcopyrite = 240/63.5 = 3.779moles

we know

1 mole of Cu → 1 mole of CuFeS2

in 3.779 moles of Cu → 3.779 moles of CuFeS2

3.779 moles of CuFeS2 = 3.779 * 183.5 = 693.45grams

CuFeS2 in kg = 0.693kg

3. How many atoms are found in 0.000256 moles?
miskamm [114]

Answer:

1.54×10^20 atoms

Explanation:

It's done by using the relation

N=n×L where,

N = number of entities present

n= amount of substance (mole)

L= Avogadro's constant which is 6.02×10^23

now from the question, given

n=0.000256

And L=6.02×10^23

N= 0.000256×6.02×10^23

N= 1.54×10^20 atoms
