STEM is an acronym meaning
Science
Technology
Engineering
Mathematics
One of the main focuses of STEM courses is on science, so you will be learning about various types of science
This is an approach at learning to have students learn all four types of subjects in one class, based on real world applications.
They are of the same period and are similar in some form
Answer:
The answer to your question is molality = 0.61
Explanation:
Freezing point is the temperature at which a liquid turns into a solid if a solute is added to a solution, the freezing point changes.
Data
Kf = 1.86 °C/m
molality = ?
ΔTc = 1.13°C
Formula
ΔTc = kcm
Solve for m
m = ΔTc/kc
Substitution
m = 1.13 / 1.86
Simplification and result
m = 0.61
Answer/Explanation:
letters are used as a sign of chemical symbols in today's time

Explanation:
You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!
Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.
Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.
Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.
Also, in elements, there is a conduction band and a valence band. Electrons occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.
So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.
