Identify the limiting reactant when 32. 0 g hydrogen is allowed to react with 16. 0 g oxygen
Mkey [24]

Answer:

Oxygen is limiting reactant

Explanation:

2 H2  +   O2  ======> 2 H2 O

from this equation (and periodic table) you can see that

  4 gm of H combine with 32 gm O2  

     H / O  =  4/32 = 1/8

       32 /16    =  2/1    shows O is limiter

         for 32 gm H you will need 256 gm O   and you only have 16 gm

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder
Elina [12.6K]

Answer:

The answers to the questions are as follows

  1. The temperature of the water bath goes up
  2. The piston moves out
  3. Heat flows out of the gaseous mixture
  4. 173.kJ flows out of the system

Explanation:

  • From the question, it is noted that 173.kJ of heat flows out of the system into the insulated water bath therefore the temperature of the water bath goes up

as seen in the relation ΔH = m·c·ΔT

Where ΔH heat measured by temperature  rise ΔT of a given mass of water m of specific heat capacity of 4.2 J/g°C

  • The amount of heat measured from previous experiment is more than the heat from the present reaction therefore since in the present reaction is constant pressure and from the first law of thermodynamics Energy can neither be created nor destroyed, the balance heat will be transformed to work evidence in the piston moving out

ΣH = Q + W  where

w = P × ΔV = P × (P₂ - P₂)

  • Heat flows out of the gaseous mixture and is sensed from the rise in the temperature of the water bath
  • 173.kJ flows out of the system
