Answer:
D
Explanation:
bothe cylinders are at room temperature so no cylinder has more themal energy. That crosses off the answers A B and C.
First, we have to know that the supply chain's stages include first, the customers and he is the main controller of the supply chain. Then, retailers, distributors (who fill the stock of the retailers and at the end the manufacturer's companies.
So when the customer starts to buy the product this represents the final stage of delivering the product to the end of the supply chain and the beginning of collecting information regarding the customer purchase.
When the customer purchases the product, the money and the information will move towards the retailer.
The retailer requests a new order to fill his stock again from the distributor and that makes money and information move towards the distributor.
The distributor requests a new order from the manufacturer's companies so, the money and the information move towards the manufacturer's companies and shipping companies.
So the Customer's purchase is the most powerful stage in the supply chain.
Balanced equation
2Pb(NO₃)₂⇒2PbO+4NO₂+O₂
<h3>Further explanation</h3>
Given
Reaction
Pb(NO₃)₂⇒PbO+NO₂+O₂
Required
Balanced equation
Solution
Pb(NO₃)₂⇒aPbO+bNO₂+cO₂
Pb, left=1, right=a⇒a=1
N, left=2, right=b⇒b=2
O, left=6, right=a+2b+2c⇒6=1+2.2+2c⇒6=5+2c⇒1=2c⇒c=1/2
The reaction becomes :
Pb(NO₃)₂⇒PbO+2NO₂+1/2O₂ x2
<em>2Pb(NO₃)₂⇒2PbO+4NO₂+O₂</em>
The balanced chemical equation is →
What is a balanced chemical equation?
A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.
A chemical equation needs to be balanced so as to make the number of the atoms of the reactants equal to the number of the atoms of the products.
The balanced chemical equation is →
