Answer:
A
Explanation:
The letter A is the correct answer
You should classify it as co2 solid as CO2(s) and that small left comes to the bottom right hand side and dry ice is a form of liquid carbon dioxide so u should write it as CO2(l) and that L comes to the bottom right hand sise
The best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
A material or ingredient supplied to a system to trigger a chemical reaction or check to see whether one occurs is known as a reagent as well as an analytical reagent. Reactant refers to a substance that is consumed during a chemical reaction. The phrases reactant and reagent just aren't frequently used interchangeably.
Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing methylating agent for carboxylic acids including phenols.
Therefore, the best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.

Answer:
The total pressure in the container is 2 atm (Option B)
Explanation:
Step 1: Data given
The initial pressure of the PCl5(g) is 1.00 atm
Volume of the container = 1.00 L
Step 2: The balanced equation
PCl5(g) ⇋ PCl3(g) + Cl2(g)
Step 3: Calculate the total pressure in the container
1mol of ideal gas has a pressure of 1 atm
If 1 mol of PCl5 completely decomposes into 1 mol PCl3 and 1 mol Cl2
Then the pressure for 1 mol PCl3 and 1 mol Cl2 is for both 1 atm
The total pressure would be 2*1 atm = 2 atm
The total pressure in the container is 2 atm
