There is an error on the above that at room temperature HG (mercury) is liquid.
-
Black solids are: carbon, manganese dioxide, copper oxide, ferric oxide.
-
White solids: anhydrous copper sulfate, magnesium oxide, phosphorus pentoxide, calcium oxide, calcium hydroxide, sodium hydroxide, sodium chloride, sodium carbonate, calcium carbonate, potassium chlorate, potassium chloride.
-
Calcium carbonate, sodium carbonate, calcium bicarbonate, sodium bicarbonate, anhydrous copper sulfate, barium sulfate.
-
Sodium carbonate, sodium bicarbonate, anhydrous copper sulfate, white phosphorus, calcium oxide, sodium oxide, sodium hydroxide.
-
Most of the chemical reagents are white, and a few have other colors
Solids: copper oxide, carbon, iron powder, manganese dioxide, ferric oxide black.
Copper elemental bright red.
Potassium permanganate purplish-red.
Solution: Such as copper salt, iron salt, ferrous salt aqueous solution is colored copper salt (blue), iron salt (yellow), ferrous salt (green).
Potassium permanganate purplish-red.

Too much ......Let's post the original question.
-
That's a lot, carbonate, barium sulfate.
-
Sodium bicarbonate (baking soda) is a white powder.
-
Too much ......Let's just post the original question.

1) Use carbon monoxide to reduce a gram of iron oxide to obtain grams of carbon dioxide, and find the chemical formula of the oxide. >>>More
Any oxide that can react with acid to form salts and water is called an alkaline oxide. Most metal oxides are basic oxides. >>>More
The gas is magnesium carbonate and sodium bicarbonate, and the precipitate is mg(oh)2, because of the excess sodium hydroxide, the amphoterics of aluminum make it not precipitate, so, according to the precipitation, the mass of mgCO3 can be found,: >>>More
The characteristic of this problem is that it does not need to be calculated step by step, but directly based on the conservation of elements. >>>More
