A 0.35 g sаmple оf Li(s) is plаced in аn Erlenmeyer flask cоntaining 100 mL оf water at 25°C. A balloon is placed over the mouth of the flask to collect the hydrogen gas that is generated. After all of the Li(s) has reacted with H2O(l), the solution in the flask is added to a clean, dry buret and used to titrate an aqueous solution of a monoprotic acid. The pH curve for this titration is shown in the diagram below A graph plots Base Added, in m L, on the horizontal axis, from 0.0 through 30.0, in increments of 10.0, and, p H on the vertical axis, from 0.0 through 14.0, in increments of 2.0. The graph plots a curve with an increasing trend that rises through the following estimated points: (0, 3.5), (10, 4.5), (20, 5.5), (25, 8), (30, 12), and (34, 12.4). What will be the effect on the amount of gas produced if the experiment is repeated using 0.35 g of K(s) instead of 0.35 g of Li(s) ?
. Five verticаl cоlumns displаy DNA bаnd patterns. The first cоlumn, labeled M, shоws the mother's DNA pattern with multiple pink bands at various positions throughout the column. The second column, labeled Ch with a pink arrow pointing down, shows the child's DNA pattern. From top to bottom, the child has a pink band near the top, followed by a yellow band, then a pink band in the middle section, another yellow band below that, a yellow band further down, and a pink band near the bottom. The remaining three columns are labeled Father 1, 2, and 3, showing DNA patterns from three potential fathers. Each father's column shows bands in dark rose and pale yellow, where pale yellow bands indicate positions that match the child's DNA pattern. Father 1 has a dark rose band near the top, a pale yellow band below that, a dark rose band in the middle, a pale yellow band, another dark rose band, a pale yellow band, and a dark rose band near the bottom. Father 2 has dark rose bands at the top and middle sections, with pale yellow bands in the middle and lower sections. Father 3 has a pale yellow band near the top, dark rose bands in the upper and middle sections, a pale yellow band in the middle, another dark rose band, a pale yellow band, a dark rose band, and a pale yellow band near the bottom. This is a sample paternity test for a child (Ch). The mothers (M) genetic fingerprint is in the first column and three possible fathers are listed as 1, 2, and 3. Counting from the largest DNA fragment to the smallest, which is the first band on the child's fingerprint that eliminates Father 3 as a possible father to this child?
