Answer the following question given this paragraph: When we conserve resources, we also cut down on the trash we produce. Americans throw out 340 million tons of trash each year. We throw out 2.5 million plastic bottles aloneevery hour! Most of what we throw out ends up in landfills ( Figure below ). In a landfill, all those plastic bottles take hundreds of years to break down. What are the problems caused by producing so much trash? Natural resources must be used to produce the materials. Land must be given over to dump the materials. If the materials are toxic, they may cause pollution. Q: What is another environmental benefit of conserving resources? Choices: - more jobs - warmer temperatures - lower prices - less trash A:
less trash

(Answer)
tendons
Ques: Answer the following question given this paragraph: The properties of the alkali metals are similar to each other as expected for elements in the same family. The alkali metals have the largest atomic radii and the lowest first ionization energy in their periods. This combination makes it very easy to remove the single electron in the outermost (valence) shell of each. The easy loss of this valence electron means that these metals readily form stable cations with a charge of 1+. Their reactivity increases with increasing atomic number due to the ease of losing the lone valence electron (decreasing ionization energy). Since oxidation is so easy, the reverse, reduction, is difficult, which explains why it is hard to isolate the elements. The solid alkali metals are very soft; lithium, shown in Figure 18.3, has the lowest density of any metal (0.5 g/cm3). The alkali metals all react vigorously with water to form hydrogen gas and a basic solution of the metal hydroxide. This means they are easier to oxidize than is hydrogen. As an example, the reaction of lithium with water is: 2Li(s) + 2H 2 O(l) 2LiOH(aq) + H 2(g). Q: The properties of the alkali metals are similar to each other as expected for elements in the same what? Choices: - class - branch - farm - family A:
Ans: family
