Circle the metals that reacted with the diluted hydrochloric acid. For those metals that did react, write molecular and net-ionic equations. Mg, Fe, Na, Cu, Ca, Pb, Zn 3. Record your observations for the reactions between the metals an the solutions of their compounds. Write “no ...
reaction of metals with dilute acids a metal salt and hydrogen gas are produced when a metal combines with a dilute acid: metal + dilute acid→ metal salt + hydrogen when sodium metal reacts with dilute hydrochloric acid, sodium chloride and hydrogen are formed: \(\begin{array}{l}2na(s)...
Metals that are more active than hydrogen can displacein acidic solutions. Complete the following equations if a reaction will occur. Add coefficients to balance the transfer of electrons. Write NR if no reaction will occur. Fe(s)+HCl(aq)→ Mn(s...
Lead and the metals ranking above lead on the activity series form salts when reacted with hydrochloric acid or sulphuric acid. These reactions also involve the liberation of hydrogen gas. The reaction between zinc and sulphuric acid is an example of such a reaction. Here, zinc sulfate and H2...
1.Some metals react with dilute hydrochloric acid to give hydrogen.Which of the following metals willNOTreact with dilute hydrochloric acid? A.copperB.ironC.magnesiumD.zinc 2.The table gives information about three different metals G, H and J.What is the order of reactivity of these metals?
Metals are classified in a variety of ways. Base metals are metals that are easily oxidized or corroded and react easily with hydrochloric acid to for hydrogen. Some examples of base metals are nickel, lead, and zinc. These metals are generally inexpensive in comparison to precious metals such...
Note:Pb reacts slowly with acids like HCl and HNO3and releases bubbles of Hydrogen gas on reaction. Reaction 2: Pb (s) + 2 H2SO4→ PbSO4+ SO2+ H2O Lead Sulphuric acid lead Sulphate (II) Sulphur Dioxide Water Note:Lead does not react with sulphuric acid, that’s why the reaction tak...
reactive metals react with water and not all the metals. for example, sodium reacts vigorously with water and oxygen and gives a large amount of heat in the process. this is why sodium is stored in kerosene so that it does not come in contact with moisture or oxygen. reaction with acids...
I collect old wire jewelry pieces and have several with actual dates on them. I show my customer these items to illustrate that gold-filled jewelry can stand the test of time. GOLD PLATED WIRE: Gold-plated metal has a very thin layer of gold on the surface of a base metal, usually ...
