Answer:
See explanation
Explanation:
Let us recall that the basic rule in writing balanced chemical reaction equations is that the number of atoms of each element on the right hand side of the reaction equation is the same of the number of atoms of the same element on the left hand side of the reaction equation.
The reaction of red hot iron and steam is written as follows;
3Fe + 4H2O → Fe3O4 + 4H2.
The decomposition reaction of ammonium dichromate is written as;
(NH4)2Cr2O7 → N2 + Cr2O3 + 4H2O
Reaction of aluminium, sodium hydroxide and water is as follows,
2Al + 2NaOH + 2H2O ----> 2NaAlO2 + 3H2
Reaction of potassium bicarbonate with sulphuric acid;
2KHCO3 + H2SO4 -------> K2SO4 + 2H2O + 2CO2
Reaction of zinc and sodium hydroxide is as follows;
Zn + 2NaOH→Na2ZnO2 + H2

You should really learn to do these! They're actually very simple
Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example,
<span>in floating of some objects on the surface of water, even though they are denser than water, and in the ability of some </span>
<span>insects (e.g. water striders) and even reptiles (basilisk) to run on the water surface. This property is caused by cohesion </span>
<span>of like molecules, and is responsible for many of the behaviors of liquids..</span>
