1)
Phản ứng xảy ra:
\({C_6}{H_{12}}{O_6} + 2AgN{O_3} + 3N{H_3} + {H_2}O\)
\(\xrightarrow{{}}{(C{H_2}OH)_5}COON{H_4} + 2Ag + 2N{H_4}N{O_3}\)
\({n_{Ag}} = \frac{{11,88}}{{108}} = 0,11{\text{ mol}}\)
\( \to {n_{{C_6}{H_{12}}{O_6}}} = \frac{1}{2}{n_{Ag}} = 0,055{\text{ mol}}\)
\( \to m = {m_{{C_6}{H_{12}}{O_6}}} = 0,055.180 = 9,9{\text{ gam}}\)
2)
Phản ứng xảy ra:
\({C_6}{H_{12}}{O_6} + 6{O_2}\xrightarrow{{{t^o}}}6C{O_2} + 6{H_2}O\)
Ta có:
\({n_{{C_6}{H_{12}}{O_6}}} = \frac{{10,8}}{{12.6 + 12 + 16.6}} = 0,06{\text{ mol}}\)
\( \to {n_{C{O_2}{\text{ lt}}}} = 6{n_{{C_6}{H_{12}}{O_6}}} = 0,06.6 = 0,36{\text{ mol}}\)
\( \to {n_{C{O_2}}} = 0,36.75\% = 0,27{\text{ mol}}\)
\( \to V = {V_{C{O_2}}} = 0,27.22,4 = 6,048{\text{ lít}}\)
