Answer:
Option 2 and 4 are correct
Explanation:
The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants. 
This is an addition reaction in which two reactants add up to form the product. 
Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive. 
Reactants have more energy than the products.  
 
        
             
        
        
        
Answer:
36.2 K
Explanation:
Step 1: Given data
- Initial pressure of the gas (P₁): 8.6 atm
- Initial temperature of the gas (T₁): 38°C
- Final pressure of the gas (P₂): 1.0 atm (standard pressure)
- Final temperature of the gas (T₂): ?
Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K
 
        
             
        
        
        
The volume is 2.23 liters of hydrogen gas.
<u>Explanation</u>:
                   moles of C = grams / molecular mass of C
                                      = 1.04 g / 12.011 g/mol.
                                      = 0.086
         The ratio between C and H2 is 1 : 1
                  moles H2 = 0.086
                                V = nRT / p 
                                   = 0.086 x 0.08206 x 316 K / 1.0 atm
                               V  = 2.23 L.
