<span>Research shows that fabric softeners decrease flame resistance. The flame resistance of a fabric can be increased in a variety of ways. Most often, the fabric is treated with special flame resistant chemicals. Synthetic fabrics, such as polyester, are naturally flame resistant. These fabrics have a property called thermoplasticity, where the fabric naturally melts and shrinks when exposed to flame. This prevents these fabrics from igniting and burning as easily as other fabrics. Basic properties of a fabric, such as porosity, can also influence flame resistance. Larger pores allow for oxygen to be more present in the fabric, making it more flammable.</span>
Explanation:
By losing or gaining electrons from its outermost orbit
The answer is both B and C
positive chromic acid test is indicated by disappearance of orange colour from chromic ions and appearance of blue-green color from Chromium (iii) ion (reduction of chromium ion from CrO4 - to Cr3+)
positive chromic test indicated functional groups that can be oxidized.
cyclohexanol can be oxidized to become cyclohexanone
and pentan-3-ol can be oxidized to become pentan-3-one
hence both B and C will show positive chromic acid test
A) tert butanol although contains alcohol functional group, cannot be further oxidized as it is a tertiary alcohol
Your answer would be 0.00285 moles.
