There is a loud pop noise depending on how much hydrogen is present. The more hydrogen there is, a louder pop will occur.
It becomes the diatomic gas H2. Hydrogen gas.
When hydrogen iodide breaks down, it forms hydrogen gas and iodine vapor. The reaction is reversible, meaning that hydrogen iodide can reform if hydrogen gas and iodine are combined.
hydrogen gas evolved
Nothing.
bubbles of Hydrogen gas is produced and it will slightly tarnish
If there is oxygen present it will burn (explosively)
blows up.
It turns into pure water that can be drunk.
water is formed H2O (2 hydrogen 1 oxygen)
When sodium reacts with hydrochloric acid, it produces sodium chloride (table salt) and hydrogen gas. The reaction can be quite vigorous, with the release of heat and bubbling due to the formation of hydrogen gas.
When metals react with bases, they often produce hydrogen gas and a salt. The metal displaces hydrogen from the base to form the salt, while hydrogen gas is released as a byproduct. This type of reaction is known as a displacement reaction.
