Answer:The answer to the question is the release of energy. The bonds that bind a molecules atom's act as a storage of energy. One way it is released is when those bonds are broken and it is released outward in every direction. This breakage results in smaller molecules and not the formation of a larger molecule.
Explanation:
Answer:
ionic bond
Explanation:
Covalent bonds are formed when two or more atoms share electrons between them. So two chlorine anions form an ionic bond with one magnesium cation for form MgCl2, a neutral chemical compound.
Answer:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
Answer:
The wood is oak.
Explanation:
Given data:
Mass of wood = 70 g
Volume of wood = 103 cm³
Wood is oak = ?
Solution:
We will calculate the density of wood then we will compare it with literature value.
Density = mass/ volume
d = 70 g/ 103 cm³
d = 0.68 g/cm³
The density of oak is 0.59 - 0.90 g/cm³.
So its true, wood is oak.
H2O, also known as water, stands for two hydrogen atoms and one oxygen atom. Hope this helps! ^^
