What volume would a 0.250 mole sample of h2 gas occupy, if it had a which has a pressure of 1.70 atm, and a temperature of 35 °c?

The volume that  would  be  occupied   by  0.25  moles   sample  of  H2  is    calculated  using  ideal  gas  equation  formula

that is  PV  =nRT

P(pressure)=  1.7  atm
V( volume)? 
n(number of moles)= 0.250  moles
R(gas  constant)=0.0821  l.atm/mol.K
T (temperature in  kelvin)=35+273  =  308k

by  making V the  subject  of the  formula V=nRT/P

=(0.250  moles  x  0.0821  L.atm/k.mol  x 308 k)/( 1.70 atm)  = 3.7  L  of  H2  gas

It is called a neutralization reaction

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
