Answer:
B. 21.07 x 10²³ molecules
Explanation:
Avogadro's Number: 6.022 x 10²³
Step 1: Set up equation
Step 2: Multiply and cancel out units
3.5(6.022 x 10²³) = 21.07 x 10²³ molecules CO₂
Step 3: Convert to proper scientific notation
≈ 2.11 x 10²³ molecules CO₂
Balanced equation :
2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
Organic Nomenclature:
Hexane is a six-carbon straight-chain alkane. The prefix "hex-" signifies the number 6 for alkanes, and the suffix "-ane" is what clarifies that this hydrocarbon has only carbon-carbon single bonds. There are no double or triple bonds.
Elaborating the equation :
The mass of hexane available for this reaction is converted to a quantity of moles by multiplying by its density to get a mass and then dividing by its molar mass. This quantity of moles is then related to the quantity of moles of oxygen by their molar ratios. According to this balanced reaction equation, every 2 moles of hexane burned will require the reaction of 19 moles of oxygen gas.

Answer:
a) Ag(NH₃)₂⁺, Cl⁻.
b) NH₃.
c) AgCl.
Explanation:
Based on LeChatelier's law, a system in chemistry can change responding to a disturbance of concentration, temperature, etc. in order to restore a new state.
In the reaction:
AgCl(s) + 2NH₃(aq) ⇌ Ag(NH₃)₂⁺(aq) + Cl⁻(aq)
When reactants are added, the system will produce more products restoring the equilibrium and vice versa. A reactant in solid state doesn't take part in the equilibrium, thus:
a) Ag(NH₃)₂⁺, Cl⁻. The addition of products will shift the equilibrium to the left
b) NH₃. The addition of reactant will shift the equilibrium to the right.
c) As AgCl is in solid phase, will not shift the equilibrium in either direction.
Answer:
Explanation:
From the question we are told that:
Pressure 
Temperature 
Volume 
Heat Produced 
Generally the equation for ideal gas is mathematically given by
Therefore
Since
Heat of combustion of Methane=889 kJ/mol
Heat of combustion of Propane=2220 kJ/mol
Therefore
Comparing Equation 1 and 2 and solving simultaneously
Therefore
Mole fraction 0f Methane is mathematically given as
The answer is 3) no change
Hope this helps
