<span>Mass was not conserved during this change. When paper burns, oxygen from the air combines with carbon and hydrogen from the paper in a chemical reaction to produce CO2 and water vapour. These waft away after the burning, just like smoke. Therefore, the paper has a lighter mass, because some of the mass it held before (from the carbon and hydrogen) has been lost.</span>

what is the effect of using higher concentration of sodium hydrogen carbonate on the rate of reaction?
Alex
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

Reaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in concentration of the gas.

Explain the different melting points between ionic and covalent bonding
yarga [219]

Ionic bonding is formed in Ionic compounds due to electrostatic force between the oppositely charged ions.


In covalent bonds electrons are shared between the atoms. In case of ionic bond the bond is stronger as there is complete transfer of electrons from one ion to the other.


Since the ionic bonds are more difficult to break than the covalent bonds, ionic compounds have a higher melting point than covalent compounds.
