Answer:
Decomposition reaction = Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
Explanation:
Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
For the Decomposition reaction to take place , <u><em>a large amount of energy ias needed</em></u>. This is because for decomposition bonds are required to breaks. Hence energy is needed to break the bonds as they have strong force of attraction.
They occur in presence of HEAT , LIGHT , ELECTRICITY.
examples of decomposition reactions are:
Here only one CaCO3 is producing two substances which are : CaO and CO2
This is also known as decompositon of Calcium carbonate and it require a lot of heat energy.
This is also a decomposition reaction , This occur in the presence of sunlight
Answer:
n = 3.0 moles
V = 60.0 L
T = 400 K
From PV = nRT, you can find P
P = nRT/V = (3.0 mol)(0.0821 L-atm/K-mol)(400 K)/60.0L
P = 1.642 atm = 1.6 atm (to 2 significant figures)

Answer :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The electrons are represented by dot.
The given molecule is, perbromate ion.
Bromine has '7' valence electrons and oxygen has '6' valence electron.
Therefore, the total number of valence electrons in perbromate ion, 
= 7 + 4(6) + 1 = 32
According to Lewis-dot structure, there are 14 number of bonding electrons and 18 number of non-bonding electrons.
Formula for formal charge :
The Lewis-dot structure of perbromate ion is shown below.
