Answer:
V = 34.55 L
Explanation:
Given that,
No of moles, n = 1.4
Temperature, T = 20°C = 20 + 273 = 293 K
Pressure, P = 0.974 atm
We need to find the volume of the gas. It can be calculated using Ideal gas equation which is :
PV=nRT
R is gas constant,
Finding for V,
So, the volume of the gas is 34.55 L.
This is an incomplete question, here is a complete question.
Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide:
In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide:
Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced.
Answer : The net chemical equation for the production of manganese is:
Explanation :
The given two chemical reactions are:
(1)
(2)
First we are multiplying reaction 1 by 3, and reaction 2 by 2, we get:
(1)
(2)
Now we are adding both the reactions, we get the overall chemical reaction.
The is common on both side, by cancelling it, we get:
The net chemical equation for the production of manganese is:
