What metal acts more vigorously with water lithium or sodium?
Sodium acts more vigorously with water compared to lithium. When sodium reacts with water, it produces more heat and releases hydrogen gas at a faster rate than lithium.
How does the metal magnesium differ from the metal calcium in their reaction with water?
Magnesium and calcium are both reactive metals, but magnesium reacts more vigorously with water compared to calcium. This is because magnesium has a higher reactivity due to its position in the periodic table, which allows it to displace hydrogen gas more easily from water. In contrast, calcium reacts more slowly with water, forming calcium hydroxide and hydrogen gas. Additionally, magnesium produces a brighter flame when burning in air compared to calcium due to its higher energy release during combustion.
When calcium metal is added to water the gas evolved doesn't catch fireBut the same gas evolved on adding sodium metal to watar catches firewhy it so?
The gas evolved when calcium is added to water is hydrogen gas, which does not catch fire on its own. However, when sodium is added to water, it reacts more vigorously to produce hydrogen gas, which can ignite due to the heat released during the reaction. Sodium is more reactive than calcium, leading to a more exothermic reaction that can ignite the hydrogen gas.
Which is more reactive calcium or xenon?
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.
What is more reactive rubidium or krypton?
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
What is more reactive calcium or more reactive?
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.
What happens when calcium oxide reacts with iron?
Iron will react with calcium oxide as iron is more reactive than calcium, therefore calcium (which is the more reactive metal) will displace calcium (the less reactive metal) to form a compound. This is called a displacement reaction.
What metal acts more vigorously with water lithium or sodium?
Sodium acts more vigorously with water compared to lithium. When sodium reacts with water, it produces more heat and releases hydrogen gas at a faster rate than lithium.

Is calcium metal more or less dense than water?
Calcium metal is more dense than water. If you had a block of calcium and dropped it in a container of water, it would sink. Note! Calcium reacts with water! Calcium metal is stored in a container beneath kerosene or another liquid to isolate the metal from air. Calcium will chemically react with the moisture in air and will thus be decomposed.
Which is more reactive calcium or xenon?
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.
What is more reactive rubidium or krypton?
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
How do group II elements differ in vigor as they react with water?
Group II elements become more vigorous as you move down the group when they react with water. For example, beryllium reacts slowly with water, while magnesium reacts more vigorously. Calcium, strontium, and barium react even more vigorously, with barium being the most vigorous among the Group II elements in water.
Does cold water have more calcium in it than warm water?
The solubility increase with the temperature, consequently the concentratiom is greater in warm water: but for calcium hydrogen carbonate and calcium carbonate the difference is not important.
What metal burns in air but only reacts slowly in water?
It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.
What is a metal element that reacts vigorously with cold water?
I'll assume your talking about a vigorous reaction and not just an oxidation that most metals will undergo in water. All of the group one elements (sodium & potassium etc) and most of the group two elements (calcium etc) will react vigorously and spontaneously in hot water. Try be a little more specific next time.
