Answer:
Erosion
Explanation:
Erosion is not a cause of metamorphism
The causes are mostly temperature, pressure, heat from the metamorphic rock
Answer:
Explanation:
1 = The given chemical reaction does not follow the law of conservation of mass because,
2 = Four hydrogen atoms are present in reactant side and two hydrogen atoms are present in product side.
3 = 1 ) The given chemical reaction does not follow the law of conservation of mass because,
CH₄ + O₂ → CO₂ + H₂O
16 g + 32 g 44 g + 18 g
48 g 62 g
Law of conservation of mass:
This law stated that mass can not be created or destroyed in chemical reaction. It just changed from one to another form.
For example:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
28 g + 96 g = 88 g + 36 g
124 g = 124 g
Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Water can only be the solvent, never the solute is the statement about a solution that is correct.
- The solute is the substance that, in general, is found in less quantity and that dissolves in the mixture.
- The solvent, on the other hand, is the substance that usually appears in greater quantity and where the solute dissolves.
- The most usual thing is that the solvent is the substance that establishes the physical state of the solution.
- Water is considered a universal solvent, since it is the liquid that dissolves the most substances, a quality linked to its status as a “polar molecule”, this is due to its ability to form hydrogen bonds with other substances.
Solubility depends on the properties of a solvent that allow it to interact with a solute in a stronger way than the solvent particles do with each other.
In particular, the polar character of water makes it an excellent solvent for polar and ionic solutes, which are called hydrophilic.
Therefore, we can conclude that water can only be the solvent, never the solute is the statement about a solution that is correct.
