Provide a structure for the following compound: ei mass spectrum: two molecular ions of about equal intensity at m/z = 180 and 182; ir: 1740 cm–1; a. δ 1.30 (3h, t j = 7 hz); b. δ 1.80 (3h, d, j = 7 hz); c. δ 4.23 (2h, q, j = 7 hz); d. δ 4.37 (1h, q, j = 7 hz).

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

The answer would be true

Answer//the law of conservation of mass.;
