Ans. Sodium is highly reactive metal. It reacts with oxygen in air at room temperature, the reaction is highly exothermic. To prevent this sodium is kept preserved under kerosene. Ans. Zinc is more reactive than iron, hence when added‘ to iron (II) sulphate, it can displace iron metaliand the colour of solution fades from green to colourless due to formation of zinc sulphate.

What Are the Effects of Sulfuric Acid on Metal? - wiseGEEK
28/6/2020· Some metal sulfates — for example, those of iron, zinc and aluminum — are very soluble in water or acids while others — like the sulfates of calcium and barium — are not. When the sulfate has low solubility, the reaction will quickly slow down or stop as a protective layer of sulfate builds up around the metal.
Calcium carbonate - Wikipedia
Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.

If the charcoal (carbon) is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel. Start with an oxide of lead, then observe what happens to an oxide of copper.
CALCIUM NITRATE TETRAHYDRATE (NITRIC ACID, …
The reaction of dilute nitric acid with copper produces NO, while more reactive metals, such as zinc and iron, react with dilute nitic acid to yield N 2 O. When extremely dilute nitric acid is used, either nitrogen gas or the ammonium ion (NH 4 + ) may be formed.

Calcium (Ca) and water - Lenntech
Calcium and water: reaction mechanisms, environmental impact and health effects Calcium occurs in water naturally. Seawater contains approximately 400 ppm calcium. One of the main reasons for the abundance of calcium in water is its natural occurrence in the
Calcium Metal | AMERICAN ELEMENTS
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms.
Calcium is an essential mineral, and when the body is chronically deficient, serious compliions can arise, including muscle and dental problems, depression, and osteoporosis. We describe these

Influence of calcium hypochlorite on the corrosion behaviour of metal …
k is the relation between depth and time (0.00327), i corr is the value of the corrosion current density (A/cm2). Table 1 summarises the results of the corrosion rate expressed in mm/year for copper, lead, and zinc in the different calcium hypochlorite solutions.
Why is calcium metal usually more reactive than …
24/9/2006· Metals such as pluum, copper, silver and gold do not react with water at all disregarding whether it is of cold water or steam. This can be understood by analyzing the oxdation series. The higher the position of the metal in the oxidation series, the easier it reacts with water or other compounds.
