Answer:
Elements only contain one type of atoms while compounds contain two or more types of atoms.
Explanation:
An example of an element is sodium --> Na (only Na atoms)
An example of a compound can be water --> H2O (contain H and O atoms)
*But the particles within a compound are all the same.
<span>The answer is A. Copper and silver are two examples of atoms that will form a metallic bond. Pure metals in solid state form nets similar to crystals, but they are not ionic. The electrons of the valence shell are shared by all the atoms. The electrons can move freely in what is called a "sea of electrons" which is what confere metals the property of conducting electricity.</span>
The given thermochemical equation is:
Δ
Mass of CO given = 24.0 g
Moles of CO = 
Finding out the heat released to the surroundings when 24.0 g CO:
Therefore, 207 kJ of heat is released to the surroundings when 24.0 g CO reacts completely.
