Barium metal reacts with water to produce barium hydroxide and hydrogen gas, according to the following equation: Ba(s) + 2 H2O(l) -> Ba2+(aq) + 2 OH-(aq) + H2(g) Some metals react with dilute acids, such as sulfuric acid, produsing a salt solution and hydrogen gas. However, if barium metal is added to water a layer of insolube barium sulfate forms at the surface, according to the equation: Ba2+(aq) + SO42-(aq) -> BaSO4(s) As an aside, calcium behaves in a similar manner. If you don;t have ready access to calcium metal, then this can be observed by placing an egg into quite dilute solutions of hydrochloric and sulfuric acids. In hydrochloric acid, the egg shell (mostly calcium carbonate) is removed. However, in sulfuric acid the reactions does not proceed due to the formation of insoluble calcium sulfate at the surface of the egg shell.
Calcium is more reactive but not as Potassium or Sodium because according to the displacement series Calcium comes as third and the last under the reactive elements of the displacement series.
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.
Calcium is more reactive but not as Potassium or Sodium because according to the displacement series Calcium comes as third and the last under the reactive elements of the displacement series.
Yes, because it is lower down in the group.
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the periodic table.
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
sodium because it's the first group and first group are the most
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
Barium is a more reactive metal and is located near the bottom of the reactivity series. It will react vigorously with water to form barium hydroxide and hydrogen gas.
Chemistry of calcium Calcium is generally more reactive than magnesium
Calcium is more reactive than xenon. Calcium is a metal that readily reacts with water and oxygen, while xenon is a noble gas that is generally unreactive due to its full valence electron shell.
calcium because there is calcium carbonate but not carbon calciumate
