The masses of the liquids are different making them have different densities
Answer: I. The number of molecules is conserved.
III. Atoms are neither created nor destroyed
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
For example: 
Thus in the reactants, there are 4 atoms of hydrogen , 2 atoms of oxygen and 2 atoms of sodium.Thus there will be 4 atoms of hydrogen, 2 atoms of oxygen and 2 atoms of sodium in the product as well.
The heat lost by the metal should be equal to the heat
gained by the water. We know that the heat capacity of water is simply 4.186 J
/ g °C. Therefore:
100 g * 4.186 J / g °C * (31°C – 25.1°C) = 28.2 g * Cp *
(95.2°C - 31°C)
<span>Cp = 1.36 J / g °C</span>
Chemsits identify elements and compounds by using the Periodic Table. All elements have Atomic Numbers, Chemical Names, Atomic Mass, Period, and are usually colored and put into their group.
the balanced equation for oxidation of isoborneol by naocl is written as follows
C10H18O + NaOCl ----> C10H16O + NaCl + H2O
isoborneol (C10H18O) react with NaOcl to form C10H16O NaCl and H2O
