Camphor is reduced to isoborneol by dissolving camphor in ethanol in erlenmeyer flask
. This reaction is followed by addition of excess sodium borohydride in small portions
. The reaction mixture is left for 10 minutes and heat is then applied to the reacting mixture. Therefore for safety purpose, during heating, the lids should not be put back on the waste containers because the reaction waste is still generating hydrogen gas that would get trapped in the container.
The reacting mixture is then poured into a beaker of ice water afterwards and Vacuum filtration and blotting dry is used to collect the precipitate instead.

Explanation:
Hispanic and Latin Americans come from diverse social, economic, and geographic backgrounds. They can be very different depending on their family heritage and national origin. However, there are some cultural similarities that tend to bring these diverse backgrounds together.
One of the most common cultural characteristics of Hispanic American culture is the Spanish language. In 1980, there were roughly 11 million Spanish speakers in the U.S. This represented 5% of the population according to the Pew Research Center. By 2012 the number of Spanish speakers increased to over 38 million, representing 13% of the U.S. population. Hispanic families often teach their children Spanish as a way of passing down their heritage and culture. This emphasis on being bilingual has helped revive the Spanish language in the U.S.
Religion plays an important role in Hispanic and Latin American culture. Hispanic and Latin Americans represent a highly Christian group. Although Americans in general have gained an increasingly secular view of society in the past few decades, a study conducted by the Hispanic Churches in American Public Life (HCAPL) reports that the majority of Hispanic and Latin Americans identify as Catholic or Protestant.
