These atoms are isotopes, they have the same number of protons which means the atoms are of the same ELEMENT, but they have different numbers of neutrons.

What is the chemical formula for the compound ammonium phosphate? Use the list of polyatomic ions and the periodic table to help
Talja [164]

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

We are given some polyatomic ions with their oxidation states. Polyatomic ions are defined as the ions which are formed from more than 2 atoms.

We need to find out the chemical formula for ammonium phosphate.

For this, the polyatomic ions used are:

Ammonium ion - NH_4^+

Phosphate ion - PO_4^{3-}

By using criss-cross method, the oxidation state of the ions are exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Thus, the chemical formula for this compound is (NH_4)_3PO_4

Hence, the correct answer is Option C.

Scientific knowledge must be supported by evidence. An idea that is not supported by evidence but is made to appear scientific i
Aloiza [94]
Answers A-C would be considered pseudoscience, then. D can be considered scientific because there is definite evidence surrounding how genes are the codes in DNA that make everything the organism may need. 

Pseudoscientific beliefs do not line up with the scientific method. Ask yourself: Which one can be proven to be a reproducible experiment that can be peer reviewed (verified) by other experts in the same field?

How do freeze-thaw cycles cause weathering?
natta225 [31]

Answer:

A. When water moves into a crack and freezes, it expands and forces the crack wider.

Explanation:

A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making the crack larger. When the temperature rises again, the ice melts, and the water fills the newer parts of the crack. Once the water freezes again when the temperature drops, the expansion of the ice causes further expansion to the crack.
