The element is likely to be metal.
The substances that are pure and only consists of atoms are called elements. They are the smallest and the fundamental unit of the compound and cannot be split to form any entity.
<h3>What are metals?</h3>
The metals are the elements that are good conductors of charge, electricity, are opaque, malleable, lustrous and ductile. They have high density and melting points. They differ from the non-metals and metalloids based on their physical and chemical properties.
The metals are more likely to donate and gain electrons to form complexes and can produce transitions. The electron gets excited when the energy is given in the form of heat and electricity and thus when comes to the ground state gives a distinct colouration.
Therefore, the element is likely to be metal.

A group of individuals of the same species that live together in the same area is a population.
Answer:
0,07448M of phosphate buffer
Explanation:
sodium monohydrogenphosphate (Na₂HP) and sodium dihydrogenphosphate (NaH₂P) react with HCl thus:
Na₂HP + HCl ⇄ NaH₂P + NaCl <em>(1)</em>
NaH₂P + HCl ⇄ H₃P + NaCl <em>(2)</em>
The first endpoint is due the reaction (1), When all phosphate buffer is as NaH₂P form, begins the second reaction. That means that the second endpoint is due the total concentration of phosphate that is obtained thus:
0,01862L of HCl×
= 1,862x10⁻³moles of HCl ≡ moles of phosphate buffer.
The concentration is:
= <em>0,07448M of phosphate buffer</em>
<em></em>

1 molecule CO2 has 2 atoms O.
1 mole CO2 has 2 moles O,
1.5 mole CO2 has 2*1.5 mole O=3.0 mole O
I believe it has something to do with the H2O molecules, because a chemical compound is not a mixture.
