There is no chemical equation since there are no signs between any of the components of what might have been a chemical equation.
Combining sodium and water results in the formation of sodium hydroxide and hydrogen gas. What the above formula does not say is that the process is exothermic and, unless handled with care, can be explosive.

Calcium plus H2O equals Hydrogen?
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
What volumes of p2 react with 3 liters of h2 to form 2 liters of ph3?
None of the following since nothing follows.
2Li plus 2H2O equals 2LiOH plus H2?
Yep

How would you find the area of a right angle triangle when its hypotenuse is greater than its height by 2.2 cm and greater than its base by 4.4 cm?
Let say A is the length of the height B the length of the base H the length of hypotenuse Then A=H-2.2 and B=H-4.4 Using Pythagore one gets H2=A2+B2 Then H2=(H-2.2)2+(H-4.4)2 or H2=H2 -4.4 H +4.84 +H2 -8.8H +19.36 H2=2H2 -13.2H +24.2 H2 -13.2H +24.2 = 0 H = (13.2-sqrt(77.44)) / 2 = 2.2 or H = (13.2+sqrt(77.44)) / 2 =11 The first solution is impossible because B=H-4.4 So H=11, A=8.8 and B=6.6 The area of the triangle is Area=(AxB)/2 = (8.8 x 6.6)/2 = 29.04
