Answer:
It's a chemical change.
Explanation:
The ingredients will react together once mixed and heated. Also the ingredients can not be pulled apart.
An atom or ion which does not have the same electronic configuration as the species [kr] is K+
The complete question is given below:
An atom or ion has the abbreviated electron configuration (Kr). Select the species that it could not A. Br" B. K+ C. Sr24 D. Rbt E. Se-
<h3>What is an atom?</h3>
An atom can be defined as the smallest particle of an element which can take part in a chemical reaction.
Some elements are
- Monoatomic; eg: C
- Diatomic; eg: O2
- Triatomic and others
- Polyatomic
So therefore, an atom or ion which does not have the same electronic configuration as the species [kr] is K+

I think it’s D but i’m not too sure
Answer:
one at the edge
Explanation:
The relation between the linear velocity and the angular velocity is given by
v = r x ω
Where, v be the linear velocity, ω be the angular velocity and r be the radius of the circular path.
As the angular velocity is constant, thus, the linear velocity depends on the radius of circular path.
So, the horse which is near to the edge has maximum radius of circular path in which it is rotating. So, the horse which is at the edge of the merry go round has maximum linear speed.
The easiest way to answer this question is just to get the answer first. The answer is A with the added comment that no chemical reaction has taken place.
Layered means that the chemicals are not soluble in one another. B is not the answer.
C is eliminated by what what was said about A.
D a solution is not a pure substance (singular) by itself. There are at least 2 chemicals together.
