The industrial synthesis of H_2 begins with the steam-reforming reaction, in which methane reacts with high-temperature steam: CH4(g) + H2O (g) → CO (g) + 3H2(g)
What is the percent yield when a reaction vessel that initially contains 63.0 kg CH4 and excess steam yields 12.9 kg H2?

  the moles   of   sulfuric acid   that are needed to react   completely with 6.4   moles   of lithium hydroxide   is 12.8   moles ( answer a)

calculation

step 1 : write a balanced   chemical equation

2lioh   + h₂so₄   →   li₂so₄   +2h₂o

step 2 : use the mole ratio   to determine   the   moles h₂so₄

from   equation above   lioh: h₂so₄   is 2: 1 therefore   the moles of h₂so₄

= 6.4   x 2/1   = 12.8   moles   of h₂so₄

an atom with no charge has 2 protons, 2 electrons, and 1 neutron.

explanation:

protons have a positive charge, electrons have a negative charge, and neutrons have no charge. as the proton is a positively charged particle and the electron is negatively charged, so the number of electrons should be equal to the number of protons so that the net charge on an atom is zero.
