Answer:
It's 10 cenimeters per second
Answer:
C₃H₈₍g₎ + 5O₂₍g₎→ 3CO₂₍g₎ + 4H₂O₍l₎
Explanation:
Propane is an alkane that burns in enough oxygen to produce carbon (iv) Oxide and heat as the only by products. Balancing the equation: The number of atoms of each kind on either side should be equal. Hydrogen on the left has eight atoms same as the right side after balancing, oxygen has 10 while carbon has 3 on each side.
Answer:
4x^3
Explanation:
Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.
Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.
For AB2(s)< -------> A(aq) + 2B(aq). But solubility of AB2= x
Ksp= x × (2x)^2
Ksp= 4x^3
Answer:
Hey, I'll help but I don't know what your options are.
Explanation:
The industrial synthesis of ammonia is spontaneous.
to to prove this one calculate the gibbs free energy(delta G)
= delta G = Delta H -T delta s
delta H = -92.2 kj in joules -92.2 x1000 =-92200j
delta s = -199j/k
T= 25+273= 298k
delta G is therefore= -92200-298(-199)=-32898j
since delta G is negative the reaction is therefore spontaneous
