Answer:
C. oil and vinegar
Explanation:
A heterogeneous mixture is a mixture where the components are not uniform in composition, like oil and water. They don't mix. When you mix oil and vinegar, you have 2 layers because oil is less dense than vinegar.
Answer and Explanation:
Ions are electrically charged particles that are formed from the removing and addition of electrons. It can be a positively or negatively charged atom.
Sodium - 23 has a net charge of + 1
Atomic number = number of protons found for the element of sodium by simply looking for the element in the periodic table = 11.
Electrons = since this atom of sodium has a net charge of + 1. Use this formula to find the number of electrons.
No. Of protons - No of electrons = ion charge.
11 - X = 1
-X = 1-11
-X = -10
X = 10.
Electrons = 10. There are 10 electrons in this atom of sodium.
Neutrons = Mass number - Atomic Number = 23 - 11 = 12.
This atom of sodium -23 had 12 neutrons.
In the mitochondria, electrons which have been released from a carbohydrate food molecule in the course of its degradation to CO2 are transferred through the membrane by a chain of electron carriers, finally reducing O2 to form water.
