The answer to this problem is Beryllium is an alkaline earth metal.
The heat energy breaks down the bonds between the molecules of the solid so the molecules become looser. Further hearing of the liquid causes the bonds to be broken down and the molecules will move further apart.
Answer:
The total mass of reactants equals the total mass of products
Step-by-step explanation:
The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:
Reactants ⟶ products
Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
Freezing point is the temperature at which a substance undergoes a phase transition from liquid to solid state. Water converts from liquid state to solid ice at a temperature of
.
Mass is the amount of matter contained in a substance. The SI unit of mass is kilogram. 1 kilogram is equal to 1000 g. One kilogram is defined as the mass of one cubic decimeter of water at the freezing point of water.
