Hydrochloric Acid (HCl) with magnesium (Mg): The magnesium dissolves into the acid. The magnesium creates hydrogen bubbles (H2). When it's dissolved it makes magnesium ions with a +2 charge (Mg2+). It turns into a white liquid with bubbles. Hydrochloric acid and chalk: The Hydrochloric acid reacts with the calcite so it forms carbon dioxide bubbles. The acid reacts to the chalk because of the limestone in it. The way to reduce it is to add diluted acid to it until u start adding water Hydrochloric and calcium: When the acid and calcium mix together it creates a mix of salt, water and carbon dioxide. There is a change of pH, temperature and colour. Vinegar and Baking soda: Vinegar and baking soda react because vinegar has a lot of acetic acid while the soda is a sodium bicarbonate. When they meet it causes a faint gas of carbon dioxide. The Carbonic acid quickly breaks into water and carbon dioxide.
There are different types of chemical that can react together. These include, reaction between a base and ÊanÊacid, reaction between Êa metal oxide and an acid and displacement reactions between different chemicals with different activityÊseries.Ê
1. NaCl + H2O= a white color salt+ water= color change 2. Ca(OH)2 + O= A pale color Limewater+ oxegen= color change
you can not make water by mixing chemicals. You can extract it from the air.
These substances are a combusible material and oxygen.
Normally combustion refers to the reaction of a fuel with oxygen.
heptane and oxygen
These substances are a combusible material and oxygen.
Since they are different substances, they will react differently in a combustion (burning) reaction.

CaCl2 is not a reaction, but a compound. It can react with certain substances such as Mg.
No, not always (opinion). So check on the internate
These substances are a combusible material and oxygen.
No. The substances that react together are the reactants. The new substances produced by the reaction are the products.
Yes :)
It is when two substances react together to form something else or change colour or fizz
The substances that can react with oxygen and give out heat and light i.e., undergo combustion are called combustible substances.
In a chemical reaction, two or more substances called reactants react, resulting in substances called products.
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
Since they are different substances, they will react differently in a combustion (burning) reaction.
This is a spontaneous reaction.
CH4+2O2 -> 2 H2O + CO2 My caps lock is not stuck
two
Reactants react together to form products.
