Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen. how many grams of hcl are required to produce 1,023 g of zncl2? equation: zn + 2 hcl --> zncl2 + h2 assume zn = 65.4 g/mole h = 1.0 g/mole cl = 35.5 g/mole

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .
