Answer:
Yes, in both cases the reactant bond must be broken before the H can bond.
Explanation:
Let us remind ourselves of the basics of the collision theory. According to this theory, chemical reaction occurs because of the collision of particles of substances in a chemical reaction system.
This means that the bond between reactants must first be broken and new bonds formed in products. Activation energy is the minimum energy required for a reaction to occur. This energy goes into the rearrangement of reactant bonds to enable them to recombine and form products.
Since the N2 bond energy is far higher than the I2 bond energy, a greater degree of energy is needed overcome the energy barrier in the reaction of H2 with N2 compared to the reaction of H2 and I2 . Therefore, the activation energy for the reaction of H2 and N2 is much higher than the activation energy for the reaction of H2 with I2.
Answer: Your answer is, <u>close to the freezing point, the water molecules start to arrange locally into ice-like structures. This creates some "openness" in the liquid water, which tends to decrease its density.</u>

Answer:
T₂ = 128.19 K
Explanation:
Given that,
The initial volume, V₁ = 12.5 ft³
Initial temperature, T₁ = -173 °C = 100.15 K
Final volume, V₂ = 16 ft³
We need to find the new temperature. The relation between temperature and volume is given by :
Put all the values,
So, the new temperature is 128.19 K.
Answer:
Phenylmethanethiol
Explanation:
Benzyl bromide is a compound from the toluene family with an alpha position substituent of bromine. When this compound (Benzyl bromide) reacts with sodium hydrogen sulfide, it yields a principal organic product called Phenylmethanethiol which is an alpha-toluenethiol that belongs to a group of aromatic compounds containing one monocyclic ring system comprising of benzene.
