What is not a typical step when performing scientific research
Gelneren [198K]

The six steps of the scientific are:

1. State the question

2. Conduct research

3. Create a hypothesis

4. Perform the experiment

5. Analyze the data

6. Conclusion

So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.

An unknown mass of aluminum requires 6290 joules to raise
Alex Ar [27]

Answer:

124.579 g

Explanation:

Amount of heat required to change the temperature of body is given by the equation given below

Q = m* c * ΔT ____________________equation A

where Q is the total heat energy required by the any object

c is the specific heat capacity of the body J/gK

ΔT is the difference of final temperature of the object and initial temperature of the object

______________________________________

Given Q = 6290 joules

c = 0.900 J/gK

To calculate the temperature in kelvin from Celsius

we can use the formula

K = C + 273

initial temperature  = 23.9°C

initial temperature on kelvin scale =  23.9° + 273 = 296.9

Final temperature  = 80°C

initial temperature on kelvin scale =  80° + 273 = 353

ΔT(temperature difference) = 353 - 296.9 = 56.1

___________________________________________

let the mass of of the  aluminum be m g

substituting the value of Q , c, ΔT in equation A we have

Q = m* c * ΔT

=> 6290 = m * 0.900 * 56.1

=> m = 6290/(0.900 * 56.1 )

=> m = 6290/50.49

=> m = 124.579 g

The mass of the  aluminum is 124.579 g

What happened to the molecule when the electron was promoted to the antibonding orbital?.
____ [38]

the bond will break

The bond will dissolve (break) if the electron absorbs a photon and is moved from a bonding molecular orbital to an antibonding orbital since there is no longer an overall stabilizing interaction.

<h3>What is an antibonding orbital?</h3>

An antibonding molecular orbital is the molecular orbital created by the destructive overlapping of atomic orbitals.

<h3>Why is it called antibonding orbital?</h3>
  • Every atom will add one electron to the bond that makes up the lower energy bond.
  • To prevent interacting with the other two electrons, the additional electron will occupy a higher energy state.
  • The antibonding orbital is the name of this higher energy orbital.

<h3>What orbitals form an antibond?</h3>
  • The bonding orbitals are home to electrons that spend the majority of their time between the nuclei of two atoms, whereas the antibonding orbitals are home to electrons that spend the majority of their time outside the nuclei of two atoms.

<h3>When an electron was elevated to the antibonding orbital, what happened?</h3>
  • In contrast, putting electrons in antibonding orbitals will make the molecule less stable.
  • The energy levels of the orbitals will determine how many electrons are filled.
  • The lower energy orbitals will be filled first, and then the higher energy orbitals.
