Answer:
375 grams of 4% NaOH solution contains 15 grams NaOH
Explanation:
Given 4% solution of NaOH = 4g NaOH/100 g Solution
=> 4g NaOH/100g Soln = 15 g NaOH / X
=> X = 15 g NaOH (100 g Soln) / 4 g NaOH = 375 grams Soln contains 15 g NaOH.

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material.

Explanation:
The reaction of phenol with SO3/H2SO4 is an electrophilic reaction. The electrophile attacks portions of high electron density in the substrate phenol.
The -OH group activates phenol towards electrophilic substitution at the ortho and para positions, hence the product(s) formed in this reaction(only one product is shown here as required by the question).
The sulphonation of phenol using concentrated sulfuric acid at lower temperature yields majorly the ortho product whereas at higher temperature the para product predominates.
