### Extraction of Manganese from RhodochrositeManganese is an essential metal that can be extracted from the mineral rhodochrosite through a two-step process. Below, we outline the chemical reactions involved in each step of this extraction process.#### Step 1: Formation of Manganese(IV) OxideIn the first step, manganese(II) carbonate (MnCO₃) reacts with oxygen (O₂) to form manganese(IV) oxide (MnO₂) and carbon dioxide (CO₂):\[ 2 \text{MnCO}_3 (s) + O_2 (g) \rightarrow 2 \text{MnO}_2 (s) + 2 \text{CO}_2 (g) \]#### Step 2: Formation of Manganese and Aluminum OxideIn the second step, manganese(IV) oxide (MnO₂) reacts with aluminum (Al) to produce manganese (Mn) and aluminum oxide (Al₂O₃):\[ 3 \text{MnO}_2 (s) + 4 \text{Al} (s) \rightarrow 3 \text{Mn} (s) + 2 \text{Al}_2\text{O}_3 (s) \]#### Yield and CalculationSuppose the yield of the first step is 73.3%, and the yield of the second step is 71.1%. Calculate the mass of manganese(II) carbonate required to produce 8.0 kg of manganese.It is important to express your answer with a unit symbol and ensure it is rounded to two significant digits.---#### Diagram Descriptions- **Reaction Equations**: The text includes two chemical reaction equations that describe the conversion processes.- **Interactive Elements**: There are interactive elements such as checkboxes and input fields, indicating a question prompt where users can type or select their answers.Be sure your response is precise and adheres to the required unit and significant digit format.

Yield of first step = 73 % Yield of second step = 71 % Mass of manganese = 8.0 kg = 8000 gm
