Answer:
True
Explanation:
Specific volume is defined as volume occupied by unit mass. Its unit is meter cube/kg. Thus, specific volume can also be defined as volume occupied by 1 kg of mass.
It is also inverse of density as density is ratio of mass upon volume.
It is an intrinsic value as it does depend upon the amount of the substance.
Therefore, the given statement is true.
In both chemical and physical changes, energy is either absorbed or emitted. For example, when ice changes to water energy is absorbed to loosen the inter-molecular bonds while during the formation of water from steam energy is emitted.
In physical changes no bonds are broken or new products formed formed as the end product has the same composition as the reactants while in a chemical change new products are formed as there is bond breaking and and formation of new bonds hence new products.
Physical changes are easily reversible while chemical changes are not reversible.
Answer:
Kc = 1.797 * 10³
Explanation:
2 NO(g) + Cl₂(g) ⇋ 2 NOCl(g)
The equilibrium constant for the above reaction , can be written as the product of the concentration of product raised to the power of stoichiometric coefficients in a balanced equation of dissociation divided by the product of the concentration of reactant raised to the power of stoichiometric coefficients in the balanced equation of dissociation .
Hence ,
Kc = [ NOCl(g) ]² / [ NO(g) ]
² [Cl₂(g)]
From the question ,
[ NOCl(g) ] = 0.851 M
[ NO(g) ] = 0.026 M
[Cl₂(g) ] = 0.596 M
Now, putting it in the above equation ,
Kc = [ NOCl(g) ]² / [ NO(g) ]
² [Cl₂(g)]
Kc = ( 0.851 M )² / (0.026 M )² ( 0.596 M )
Kc = 1.81 * 10³
It would be known as a meth_(insert - ane, - ene, and -yne) hydrocarbon.
1 bond = -ane
2 bonds = - ene
And so on.
Test Your Hypothesis by Doing an Experiment
Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.
