Concept explainers
Interpretation:
The effects of strong acids and strong bases on the skin should be explained.
Concept Introduction:
Acids are substances that donate H+ ion/s in aqueous solutions. The effect of an acid on skin depends on its strength. For example: acetic acid is weak acid, commonly known as vinegar which is eatable and does not harm skin, when comes in contact. But strong acid, such as acids used in cars can cause serious skin injuries if come in contact.
Bases are substances that donate OH- ion and accept H+ ion in the aqueous solution. Strong bases can accept this proton from any molecules due its strong basic nature resulting damage to that molecule. Ammonia and bleach are examples of bases that cause burn when comes in contact with skin.

- 13.84. Chlorine atoms react with methane, forming HCI and CH3. The rate constant for the reaction is 6.0 × 107 M¹ s¹ at 298 K. When the experiment was run at three other temperatures, the following data were collected: T (K) k (M-1 s-1) 303 6.5 × 107 308 7.0 × 107 313 7.5 x 107 a. Calculate the values of the activation energy and the frequency factor for the reaction. b. What is the value of the rate constant in the lower stratosphere, where T = 218 K?arrow_forwardMy Organic Chemistry textbook says about the formation of cyclic hemiacetals, "Such intramolecular reactions to form five- and six-membered rings are faster than the corresponding intermolecular reactions. The two reacting functional groups, in this case OH and C=O, are held in close proximity, increasing the probability of reaction."According to the book, the formation of cyclic hemiacetals occurs in acidic conditions. So my question is whether the carbonyl group in this reaction reacts first with the end alcohol on the same molecule or with the ethylene glycol. And, given the explanation in the book, if it reacts first with ethylene glycol before its own end alcohol, why would it? I don't need to know the final answer. I need to know WHY it would not undergo an intermolecular reaction prior to reacting with the ethylene glycol if that is the case. Please do not use an AI answer.arrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward
