Answer:
The s stands for the phase of that element or compound. The phase solid is represented by (s). In this problem it is saying solid sodium (Na) is reacting with Bromine (Br) gas to form sodium bromide.
Explanation:
To be honest it have to be c because it shows things
Answer:
Oxygen gas
Explanation:
Potassium chlorate KClO3 decomposes thermally to form potassium chloride KCl and oxygen gas is given off. This is in the presence of a catalyst, manganese iv oxide.
Hence, what is being said in essence is that when potassium chloride is heated in the presence of manganese iv oxide catalyst, oxygen is given off as the gaseous product with the formation of potassium chloride.
The chemical equation for the reaction is :
2KClO3 ——-> 2KCl + 3O2
This procedure is one of most important ways through which oxygen can be produced in the laboratory and can be used as a source of oxygen is industrial processes if on a large scale
Answer:
yes is very possible to be
Dry air is the choice that is vibrating the fastest because its in a gas form which causes particles to vibrate quickly because of the heat.
