Single replacement reaction
-There are five general types of reactions . These includes; combination, decomposition, single replacement, double replacement, combustion.
-Single replacement reactions are reactions in which both reactants and products consist of an element and a compound . For example in our case, for reactants, the element is Aluminium (Al) and the compound is NiBr2, and for products the element is Ni and the compound is AlBr3.
-Single replacement reactions involves a chemical change in which one element replaces a second element in a compound . In this case Aluminium (Al) replaces nickel (Ni) in the compound NiBr2.
2 Al + 3 NiBr₂ = 2 AlBr₃ + 3 Ni
Classification : single replacement
hope this helps!
the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.
a is incorrect because when water solidifies, it becomes ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.
b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.
c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.
e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
