Answer:
The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.
Explanation:
Answer:
The question is incomplete because the options are not given, here are the options gotten from another websites.
a. It is correct because each ion is a pure substance, so sodium phosphate is made up of two pure substances.
b. It is correct because the composition of sodium phosphate changes depending on the sample.
c. It is incorrect because sodium phosphate is a compound that has a single composition.
d. It is incorrect because the two types of ions in sodium phosphate cannot be seen.
The correct option is C.
It is incorrect because sodium phosphate is a compound that has a single composition
Explanation:
It is incorrect because sodium phosphate is a compound that has a single composition because a Compound is substance that contain two or elements which combine together by chemical bonds or the atoms of the element are joined together by chemical bonds. From our question, sodium phosphate is a compound because it is composed of two elements which are sodium and phosphate and these elements atoms chemically combine together.
Answer:
-0.398
Explanation:
pOH is a measure of hydroxide ion (OH-) concentration in a solution. A basic solution If a solution has pOH less than 7 then it is a basic solution and if pOH is greater than 7 then it is an acidic solution. Neutral solutions have pOH equal to 7.
![pOH=-\log \left [ OH^- \right ]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5Cleft%20%5B%20OH%5E-%20%5Cright%20%5D)
To find pOH of 2.5 M NaOH, solve ![pOH=-\log \left [ 2.5 \right ]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5Cleft%20%5B%202.5%20%5Cright%20%5D)
= -0.398
