Alkanes can, the double bonds mean that something can be added across it
Answer:
TiCl2
Explanation:
Mass of the chloride of titanium= 1.31 g
Mass of titanium= 0.528 g
Therefore mass of chlorine = 1.31-0.528 = 0.782 g
To determine the empirical formulae of the titanium chloride, divide the mass of each element by its relative atomic mass and divide through by the lowest ratio.
Ti- 0.528/48 = 0.011, Cl- 0.782/35.5 = 0.022
Ti- 0.011/0.011 , Cl- 0.022/0.011
Ti- 1, Cl-2
Hence the required empirical formula is TiCl2
Answer: an ice pack getting cold (due to ammonium nitrate dissolving in water inside the pack)
Explanation:
Endothermic reactions: These are the reactions in which energy is required in the reaction. The energy of the products are more than the energy of the reactants.
Exothermic reactions: These are the reactions in which energy is released in the reaction. The energy of the products is less than the energy of the reactants.
a) water droplets condensing on a soda can on a hot summer day : As the gaseous molecules are changing into liquid phase, energy is released and is exothermic
b) an ice pack getting cold (due to ammonium nitrate dissolving in water inside the pack) : As the temperature is decreasing , energy is absorbed by the surroundings and thus is endothermic
c) thermite reaction between iron(III) oxide and aluminium (spectacular flames are observed) : As flames are produced, the energy is released and thus is exothermic
d) freezing water to make ice cubes : As the liquid molecules are changing into solid phase, energy is released and is exothermic
Answer:
It does not have a regular composition.
Explanation:
Explanation:
When a strong acid, say 
reacts which a weak base, say 
, the reaction is shown below as:-
The salt further reacts with water as shown below:-
Formation of 
lowers the pH value of the solution as more hydrogen ions leads to less pH.
