Identity the step that is not part of the scientific method.
horrorfan [7]

Options:

conduct an experiment

form a hypothesis

draw a conclusion

state the cause

Answer:

'<u>State the cause'</u> is not part of the scientific method.

Explanation:

The scientific method has three wholistic steps:

  • Test the hypothesis
  • Make observations from the experiment to the hypothesis
  • Draw a conclusion or prediction from the experimental results.

A cause is neither a scientific term nor is it part of the  processes of experimentation.

I hope this was helpful.

Arrange the forms of electromagnetic radiation in order of decreasing energy (from highest energy to lowest energy). You are cur
solmaris [256]

Answer:

gamma rays > X-rays > ultraviolet radiation > visible light > infrared > radio waves.

Explanation:

Electromagnetic waves are those waves that require no material medium for propagation. They can travel through space and they all move at the speed of light.

Electromagnetic waves are composed of both electric and magnetic fields which are mutually at right angles to each other.

The order of decreasing energy of electromagnetic waves is;

gamma rays > X-rays > ultraviolet radiation > visible light > infrared > radio waves.

What is true of a sulfide ion (S2-)?
ratelena [41]

Answer: D) It has two more electrons than protons.

Explanation: Sulphur (S) is an element with atomic number 16 and thus contains 16 electrons. A neutral atom contains equal number of protons and electrons.

S:16:[Ne]3s^23p^4

An atom on losing electrons gains positive charge and on gaining electrons gain negative charge.

Sulphide ion (S^{2-}) is formed by gaining 2 electrons to attain stable configuration of argon and thus contains two more electrons than protons.

S^{2-}:18:[Ne]3s^23p^6:[Ar]
