What reacts with metals to produce hydrogen gas?
Metals often form hydrides and are found widely in chemistry. notable examples are LiAlH4 potent reducing agent in organic chemistry and NaH powerful base ~50 PKa. in addition hydrogen can adsorb onto metal surfaces. this is important in the catalysis of hydrogenation reactions where Hydrogen gas is reacted with unsaturated compounds by using a platnium surface(many other conditions/metal catalysts are also used)
The process of oxygen reacting with a metal to form rust?
corrosion
How are transition metals compounds?
non-reactive
What does the arrow in a chemical equation mean-?
Pointing right, "react to form". Pointing left (rare, but I've seen it a couple of times), "are produced by the reaction of". If it's a double arrow, then "exist in equilibrium with".The arrow means yields.
What is the difference between cold rolled galvanized and hot dipped galvanized steel?
Hot-dip galvanized pipe is made by reacting the iron substrate with molten metal to form an alloy layer, thus combining the substrate with the coating. Hot-dip galvanizing requires pickling of the steel pipe to remove iron oxide from the surface of the pipe. After pickling, it is washed in an aqueous solution of zinc chloride or ammonium chloride or a mixture of ammonium chloride and zinc chloride and then sent to a hot dip galvanizing bath. Hot dip galvanizing has the advantages of strong adhesion, uniform coating and long service life. Cold galvanizing is what we call electro-galvanizing. The amount of galvanization is very small, and the corrosion resistance of cold galvanized pipe itself is very different from that of hot galvanized pipe, so many construction projects do not use cold galvanized pipe. At present, the Ministry of Construction has officially stated that technically backward cold galvanized pipes need to be eliminated, and cold galvanized pipes will not be allowed to be used as water and gas pipes in the future. Shanghai Changzheng's cold rolled steel sheets are of superior quality and are the choice of most people. Buy steel plates from Shanghai Changzheng.
What is the word equation of iron oxide plus hydrochloric acid?
The word equation for iron oxide reacting with hydrochloric acid is: iron oxide + hydrochloric acid → iron chloride + water.
Can potassium chloride be prepared from zinc and hydrogen chloride?
No, reacting zinc with hydrogen chloride will yield zinc chloride and hydrogen gas. Potassium chloride can be prepared by reacting potassium with hydrogen chloride or (more safely) potassium hydroxide with hydrogen chloride.
What is the word equation for Ammonia reacting with hydroelectric acid?
I am guessing that you mean hydrochloric acid, and the reaction is ammonia plus hydrochloric acid gives ammonium chloride; NH3 + HCl => NH4Cl
What is the product of hydrochloric acid plus ammonia?
they reacting togethor. Then form NH4Cl asa result.
Calcium reacting with hydrochloric acid?
When calcium reacts with hydrochloric acid, calcium chloride and hydrogen gas are produced. The balanced chemical equation for this reaction is Ca + 2HCl → CaCl2 + H2. This is a single displacement reaction where the more reactive calcium displaces the hydrogen from hydrochloric acid.
What is an acid containing one ionizable hydrogen ions?
Triproctic Acids contain three ionizable hydrogen ions. such as H3PO4
What is the acid from which the table salt can be formed?
if table salt means sodium chloride then it may form from hydrochloric acid by reacting with sodium hydroxide, but table salt is not pure sodium chloride it also contains a small quantity of magnesium and calcium chloride.
Suggest why magnesium chloride can be made by mixing magnesium with hydrochloric acid but copper chloride cannot be made by mixing copper with hydrochloric acid?
Copper is an inert metal and below hydrogen in electro chemical series therefore can not displaced hydrogen from acids so copper can not be converted directly to salts by reacting with acids, however concentrated sulphuric acid reacts with copper on heating in presence of atmospheric oxygen forming the copper sulphate, chlorides and other salts are prepared from its sulphate salt.
What metal would you use to make zinc chloride?
To make zinc chloride, you would typically use zinc metal as one of the starting materials. By reacting zinc metal with hydrochloric acid, zinc chloride can be produced.
What is the balanced chemical equation for sodium and hydrochloric acid reacting to produce sodium chloride and hydrogen?
Do not try this! 2Na +2HCl --> 2NaCl + H2 The last 2 should be a subscript.
What is sodium chloride made up from?
Sodium chloride is formed from sodium and chlorine.
What is a word equation for zinc reacting with hydrochloric acid?
Word Equation: Zinc + Hydrochloric Acid à Zinc Chloride + Hydrogen Chemical Equation: Zn + HCl à ZnCl2 + H2
