The correct answer is D
According to the law of conservation of mass, mass can not be destroyed or lost, it can just be rearranged in space, turned into energy etc.
Therefore, in our of example the wood was burned and turned into ashes. Even though the ashes weight less than the original wood, some of the solid mass of the wood was converted to gas and energy, so the overall mass remained the same.
Answer:
O the molecular formula
Explanation:
The true ratio of atoms in a molecule or formula unit is called the molecular formula.
The molecular formula of a compound shows the true number of atoms that are combining to form a compound.
For example, the molecular formula of water is H₂O.
- Empirical formula of a compound is its simplest ratio.
- When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
53.6 hectometer
536 meters
536,00 centimeters
Explanation:
It is known that heat (Q) required to change the phase of a given sample of mass m will be as follows.
........ (1)
where, 
= latent heat of fusion
Similarly, 
= mL_{v}[/tex] ....... (2)
where, 
= latent heat of vaporization
As it is known that value of latent heat of fusion of water is 334 J/g and latent heat of vaporization of water is 2260 J/g.
Hence, equating both the equations as follows.
= 
= 
= 
= 54.13 g
Hence, we can conclude that 54.13 grams of ice will melt.
