what gas?????

Question

what gas is formed when water reacts with metals such as soduim and calicum?

Answer 1

First you would want to know the equations that form a gas
Na(s)+H20(l)=?
Ca(s)+H20(l)=?

Looking at this you would know that problably a single replacement occurs:

= NaO(s) + H2(g)
=CaO(s) +H2(g)

The gas formed is just hydrogen gas (H2)

Answer 2

Na + H2O ------> NaO + H2
Ca + H2O ------> CaO + H2

in a decreasing activity series Na and Ca are above the other elements except lithium and Potassium. In relation to this, other elements can be replaced by the said metals in question and that includes hydrogen.
For the given metals, they can replace Hydrogen in both water and acid but for some metals they cannot.

So for this kind of reaction Hydrogen gas (H2) has evolved.

Answer 3

Hydrogen gas, H2. This is an oxidation-reduction (or redox) reaction, since an exchange of electrons take place. Metals react very easily to donate their electrons. The hydrogen in water accepts the electrons from the metal to form diatomic hydrogen gas.

Answer 4

I went however the NBC direction in BCT. you always positioned your masks on first, then sound the alarm. they won't hear you very nicely, yet there's a hand sign particularly for that reason. You shout gas, gas, gas collectively as doing considered one of countless gas alarm alerts. So regardless of in the event that they might't hear what you assert, the certainty which you're donning your masks and giving the right sign skill there is gas. Your instructor became incorrect. with the aid of how, for people who think of the masks is a mute factor as a results of absorbtion in the process the floor. we are issued charcoal pads and positioned on finished physique suits. The charcoal absorbs the chemical on the uncovered factors.

Answer 5

This is a single replacement reaction (which is a type of oxidation-reduction reaction). In single replacement reactions metals replace the positive part of the compound so the metals would replace the hydrogen in the water. If you write the water as HOH instead of H2O you can see what happens better.

ex. 2Na + 2HOH = 2NaOH + H2

Answer 6

When metals react with water they generally form a metal oxide and hydrogen (H2) gas.

Answer 7

hydrogen gas is emitted from the reaction of water with metals like sodium and calcium.

Answer 8

when water reacts with sodium the sodium replace the hydrogen of water and the hydrogen elaborates and sodium reacts with water oxygen to form sodium oxide

Answer 9

Yes, it's hydrogen gas.

Answer 10

hydrogen
