K + I - > KI
Potassium (needs to lose 1 electron) responds with Iodine (needs to pick up 1 electron) to fulfill both component's octet, shaping a salt, potassium iodide
This is a similar case for NaCl, simply unique components. Trust this made a difference.
Calculate the molar mass of Ca3P2 in grams per mole or search for a chemical formula or substance.
The spinal cord is part of the central nervous system
The dependant variable is what you measure during the experiment and what is affected in the experiment (this is for question 4) so the answer would be D
A=mass number (protons + neutrons)
Z=atomic number (protons)
N=number of neutrons.
A=Z+N
Data:
A=24
N=13
Therefore:
24=Z+13
Z=24-13=11
Answer: The atomic number of this atom is 11. (The element is sodium)
