Answer:
products are copper and aluminium chloride
reactants are aluminium and copper chloride
Explanation:
products are formed at the end of a reaction
reactants are what's reacting to form the products ie the things at the start of the equation
Answer:
(a) a first order reaction = s^-1.
(b) a second-order reaction = L(mol·s)
(c) a third-order reaction = s⁻¹M⁻²
Explanation:
Okay, this question is a question that has to do with kinetics that is how reaction occurs.
So, the RATE LAW is one of the concept that is being used in determining conditions of chemical reactions. The relationship between the the reactants molarity and the reaction rate is known as rate law. That is to say;
Rate law = K × Molarity.
So, In this question we are given that the concentrations measured in moles per liter, and time in seconds.
The FIRST ORDER REACTION has its unit for rate constant as per seconds(s^-1).
That is from; Rate law = k
Molarity/s = k × Molarity.
k = s^-1
(b) a second-order reaction;
Rate law= k × (molarity)^2.
Molarity/s = k × (Molarity)^2.
k = L(mol·s)
(c) A third-order reaction = s⁻¹M⁻²
Same thing applies.
<h2>2 Pb(NO3)2 – 2 PbO + 4 NO2 + O2: Decomposition reaction </h2>
Explanation:
Chemical reaction
When two or more substances react and form some new substance it is called as chemical reaction .
There are so many reactions , out of which decomposition is also one type .
It is explained below :
Decomposition reaction
it is the type in which a reactant breaks up into its constituents either by heating or passing current or in presence of light .
That is :
(a) Photo decomposition (breaking in presence of light )
Examples AgCl-----Ag+Cl₂
(white ) (grey )
(B)Electrolytic decomposition : breaking by passing current
Example : NaCl------Na+Cl₂
©Thermal decomposition : breaking by heating )
Example : Pb(No₃)₂-----PbO+NO₂+O₂
(reddish brown gas )
ACTIVITY TO DEMONSTRATE : heating of ferrous sulphate
FeSO₄.7H2O------FeSO₄+7H₂O
(GREEN )
FeSO₄-----------------heat -------Fe₂O₃+SO₂+SO₃
This question is done considering : Identify the type of reaction
2 Pb(NO3)2 – 2 PbO + 4 NO2 + O2
Answer:
False
Explanation:
Catalysts are reusable because they keep the chemical reactions moving without being consumed.
