Answer:

The answer to your question is FeS₃

Explanation:

Data

mass of Fe = 3.78g

mass of S = 5.95 g

mass of FeS

Chemical Balanced Reaction

                           Fe   +   S     ⇒    FeS

Process

1.- Convert the grams to moles

For Iron

                              55.85g of Fe --------------  1 mol

                               3.78 g of Fe -----------  x

                               x = (3.78 x 1) / 55.85

                               x = 0.0677 moles

For Sulfur

                              32 g of S ------------------- 1 mol

                               5.95 g     ------------------  x

                               x = (5.95 x 1)/32

                               x = 0.185 moles

2.- Divide by the lowest number of moles

Iron = 0.0677 /0.0677 = 1

Sulfur = 0.185 /0.0677 = 2.73 ≈  3

3.- Write the empirical formula

                                 FeS₃

Answer:FeS

Explanation:

Mass of sulphur=5.95-3.78=2.17g

Fe S

3.78/56. 2.17/32

0.0675/0.0675. 0.0678/0.0675

1:1

Empirical formula=Fe1S1=FeS

A 150-lb person burns about 2700 Calories to run a marathon. How much energy is burned in kJ?
Alex17521 [72]
The question above is simply asking us to convert the value from calories into kilojoules. Therefore, we need some factor to multiply to be able to convert it to such units. For calories to kJ, the factor would be 4.184.

2700 cal ( 4.184 kJ/cal) = 11296.8 kJ

LuckyWell [14K]
When alpha particles are used to bombard gold foil, most of the alpha particles pass through undeflected. This result of the experiment indicates that most of the volume of a gold atom consists of unoccupied spaces. This was an experiment done by Ernest Rutherford which allowed him to verify the presence of the a small region positive charge in an atom which is called as the nucleus of the atom. Most of the alpha particles pass through the foil while a certain amount were deflected. Those that pass through confirmed that there is a large area that is unoccupied in an atom.

<h2>Answer: O: 1s22s22p4</h2>

Explanation: In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.
