First of all you cannot add cold. You can remove heat. In the first instance gas minus heat is cold gas. Then, depending on the substance, you can have mainly liquid or solid.
2NaBr (s) + Cl2 (g) --------> 2NaCl (s) + Br2 (g)
Not the equation but the products are solid liquid or gas; and this is determined experimentally.
water equals liquid , water vapor equals gas and ice equals solid
Zinc plus hydrochloric acid equals zinc chloride plus hydrogen gas.
Solid lithium iodide decomposes into solid lithium and iodine gas.
Solid magnesium metal plus oxygen gas produce solid magnesium oxide.
The equation is balanced, but it's not as simple as it can be. The correct equation is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
The equation that describes aerobic cellular respiration is Glucose plus Oxygen which equals Carbon Dioxide plus water plus energy. Respiration is the gas exchange and cellular respiration produces ATP.
Mg + 2HCl --> MgCl2 + H2 Magnesium plus hydrochloric acid equals magnesium chloride plus hydrogen gas.
A gas plus a liquid is.......I have no idea thats why I am asking you guys!!
