Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.
can someone help me with my qustions?
Answer:
Solids for sure
particles of solid cant flow.
Density = 968 g/cm³
mass = 250 g
Volume = ?
Therefore:
D = m / V
968 = 250 / V
V = 250 / 968 => 0.26 cm³
Answer C
