An unknown gas is collected by water displacement. The barometer reading is 100.3 kPa and the temperature is 20.0 °C. The water vapor has a pressure of 2.34 kPa at 20.0°C. What is the pressure of the dry gas?​

c. electrical charges of ionic bonds.

  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
