If you are comparing 2 metals, the metal with a higher <u>Number of free ions</u> will react with EDTA first
<h3>What is EDTA ?</h3>
EDTA is a type of chemical which binds certain metal ions such as calcium and magnesium. some of the functions of EDTA includes:
- Preventing blood clotting of blood samples
- prevention of the formation of Biofilm by bacterias
The EDTA will readily react with metals which have a hiogher number of free ions that it can bind with.
Hence we can conclude that If you are comparing 2 metals, the metal with a higher <u>Number of free ions</u> will react with EDTA first.

Answer:
A: Antibonding molecular orbitals are higher in energy than all of the bonding molecular orbitals.
Explanation:
Molecular orbital theory describes <u>covalent bonds in terms of molecular orbitals</u>, which result from interaction of the atomic orbitals of the bonding atoms and are associated with the entire molecule.
A bonding molecular orbital has lower energy and greater stability than the atomic orbitals from which it was formed. An antibonding molecular orbital has higher energy and lower stability than the atomic orbitals from which it was formed.
Electrons in the antibonding molecular orbital have higher energy (and less stability) than they would have in the isolated atoms. On the other hand, electrons in the bonding molecular orbital have less energy (and hence greater stability) than they would have in the isolated atoms.
Answer:
Direct evidence from rock samples and indirect evidence from seismic waves may account for why scientists have two ways of thinking about earth's layers
Explanation:
Scientists who study about the earth's structure and components called geologists have two main types of evidence to learn about Earth's interior namely
1. direct evidence from rock samples
2. indirect evidence from seismic waves
Direct evidence From Rock Samples
Scientists examine rocks from inside the Earth and these rocks give them clues about Earth’s structure. Some scientists have drilled holes as much as 12 kilometers into Earth and bring up samples of rock. From these samples, they can make inferences about conditions deep inside Earth, where these rocks formed. In addition, forces inside Earth sometimes blast rock to the surface from depths of more than 100 kilometers. These rocks from deep within the Earth provide more information about the interior.
Indirect evidence From Seismic Waves
Since scientist cannot look inside Earth, they have devised an indirect methods of observation by using seismic waves. When earthquakes occur, they produce seismic waves. Scientists record the seismic waves and study how they travel through Earth. The speed of seismic waves and the paths they take reveal the structure of the planet. Using data from seismic waves, scientists have learned that Earth’s interior is made up of several layers with each layer surrounding the layers beneath it.
