Answer:
202.20 cm^3/s
Explanation:
Hello,
I'm sending a photo showing the solution for this exercise.
The solution of the 2x2 system could be achieved by using a calculator or any available algebraic method.
Best regards.
∆H = m x s x ∆T, where m is the mass of the reactants, s is the specific heat of the product, and ∆T is the change in temperature from the reaction.
Answer:
synthesis
Explanation:
The reaction given is a synthesis reaction or combination reaction.
Given equation:
NH₃ + HCl → NH₄Cl
In a synthesis reaction, a single product is formed from two or more reactants
A + B → C
The formation of compounds from the union of constituent elements also falls into this category.
So the given reaction is a synthesis reaction.
In a decomposition reaction two or more products are formed from a single reactant
In a single replacement reaction, one substance replaces another.
In double replacement reactions partners in a chemical specie are exchanged.
Therefore the given reaction is a synthesis reaction
Explanation:
Specific heat capacity of gold (S)
= 0.126 J /kg°C
mass (m) = 350 g = 0.35 kg
difference in temperature (dt)
= 88.5°C - 24.6°C
= 63.9° C
Now
Energy released (Q)
= m*s*dt
= 0.35 * 0.126 * 63.9
= 2.81799 Joule
Hope it will help :)
