What is the chemical formula for zinc (II) phosphate?
Answers
Answer:
Zn^3(PO4)2
Explanation:
thats the formula
The chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.
Zinc (II) phosphate is an inorganic chemical compound that is made up of zinc cations and phosphate anions .The chemical formula for zinc (II) phosphate is obtained by combining three zinc cations with two phosphate anions to achieve the neutral charge.
Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.
Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.
It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.
Thus, chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.

what is an orbital?
Answers
Answer:
Electric Patterns and has many different variations.
Explanation:
Criminalist Julie Sandel is investigating a series of threatening notes written in pencil and sent to a local politician. A suspect is arrested and Julie directs the suspect to prepare writing samples to compare to the writing on the notes. She has the suspect sit at a desk in an empty office and gives him a pen and a piece of paper. She begins to read one of the notes and asks the suspect to write the words she dictates. After reading about half a page, she stops, then dictates the same part of the note a second time for the suspect. At one point, the suspect indicates that he does not know how to spell one of the words, so Julie spells it for him. After completing the task, Julie takes the origi- nal notes and the dictated writing from the suspect to a document examiner. What mistakes, if any, did Julie make?
Answers
Answer:
See explanation
Explanation:
Julie Sandel, the Criminalist made several mistakes in handling this investigation. They include;
It is true that handwriting can be deduced by comparing a suspects's handwriting to the questioned document, however Julie made a mistake by not making the suspect to write many pages. The suspect may intentionally decide to change his/her hand writing. This trick can be neutralized by asking the suspect to write several pages.
Secondly, the suspect ought to have been given a pencil and paper similar to the one used to write the threatening document. Rather, Julie gave the suspect a pen.
Thirdly, the suspect only wrote half a page instead of a full page. Secondly, Julie took only two exemplars when she should have taken more.
She should not have dictated the spelling of any word to the suspect. The examiner is not supposed to do that.
The threatening documents should have first been shown to the document examiner before taking the exemplars.

A reaction begins with 130.5g of substance X and substance Y. How many grams of
substance X and Y are there at the end of the reaction?
A) not enough information provided
B) 100g
C) 65.25g
D) 130.5g
Answers
Answer:
130.5g
Explanation:
At the of the reaction, the combined mass of X and Y will be 130.5g.
The premise for this conclusion is based on the law of conservation of matter.
This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
In essence, in a chemical reaction, there is no mass loss.
The amount of product in the reaction is expected to be the same as the amount of reactants used in the experiment. When we start with 130.5g then we should end with 130.5gWhat constitutes a solar system?

What element is in period 6 with 2 valence electrons?
Answers
Answer:
Barium
Explanation:
I think that's the answer
The element in period 6 with 2 valence electrons is Barium.
The periodic table has been organized into periods and groups. The period is in an horizontal arrangement while group is vertical arrangement. The elements that can be found in period 6 are Beryllium, Magnesium, Calcium, Strontium, Barium etc. Elements in the same group have the same number of valence electrons. This means that elements in group 2 have 2 valence electrons. Barium possess two valence electrons because it is in group 2 and it is also in period 6. Therefore, the element in period 6 with 2 valence electrons is Barium.Learn more at: https://brainly.com/question/24089206?referrer=searchResults

Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.
