Answer:
The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other.
Explanation:
if the states of matter are cited, is to look for aqueous reactants and the formation of one solid product (since the reaction typically generates a precipitate).
Answer:
an oxygen atom with 8 electrons, 8 protons and 9 neutrons
Answer:
Explanation:
Tenochtitlan was located on a swampy island in Lake Texcoco in what is today south central Mexico. The Aztecs were able to settle there because no one else wanted the land.

The answer is evaporation
<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The nuclear reaction for the fission of Americium-244 isotope follows:

<u>To calculate Y:</u>
Total mass on reactant side = total mass on product side

Hence, 3 neutrons are produced in the above nuclear reaction.
