Yes: Calcium and magnesium are successive elements in the same wide form Periodic Table column.
It seems unlikely that dolomite would react with iron to any significant degree. Dolomite is calcium magnesium carbonate; both calcium and magnesium are higher on the activity series than iron.
Calcium nitrate and magnesium will not react since calcium is more reactive than magnesium and so, magnesium does not displace calcium (See Reactivity Series). However, if Calcium nitrate is in aqueous solution (dissolved in water), some bubbles may be seen when Magnesium is added to it, since the Magnesium would be reacting with the water and producing hydrogen bubbles.
no, it wouldn't calcium is above magnesium in the reactivity series which means that magnesium can't oxidize calcium. calcium can oxidize magnesium so calcium would react with magnesium nitrate with formation of metallic magnesium and calciumnitrate.
When an antacid tablet dissolves in water, it undergoes a chemical change. The active ingredients in the tablet, like calcium carbonate or magnesium hydroxide, react with stomach acid (hydrochloric acid) to neutralize it, forming salt and water. This chemical reaction helps to relieve acidity in the stomach.
Dissolving magnesium in a solution can change its chemical properties and reactivity. The magnesium atoms become ions in the solution, which can react more easily with other substances. This can lead to new chemical reactions and potentially alter the behavior of the magnesium in the solution.
For example calcium carbonate react with hydrochloric acid and form a solution.
Hydrogen gas is released when calcium and water react.
When you mean different type of magnesium, it can either be isotopes of magnesium or magnesium compounds. If you mean isotopes, i doubt any isotopes of magnesium is able to react with its calcium brethren. If you're talking bout magnesium compounds, reactivity between the metals depends on the electrochemical series, since magnesium is more electronegative, therefore i dont think calcium is able to displace magnesium from its compound. but magnesium is able to displace calcium from its compound.
When potassium, magnesium, and manganese are mixed with water separately, they will undergo different chemical reactions. Potassium will react vigorously with water, magnesium will react slowly to produce magnesium hydroxide and hydrogen gas, while manganese will not react with water under normal conditions.
When hard water reacts with soap, it forms an insoluble scum due to the reaction between the calcium and magnesium ions present in the water with the soap. The calcium and magnesium ions react with the soap molecules to form calcium and magnesium salts of the fatty acids, which are insoluble and appear as white scum in the water.
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.
3Mg + N2 --> Mg3N2 Magnesium and nitrogen react to form magnesium nitride.
