Transcribed Image Text:### Stoichiometry: Solving for a Reactant Using a Chemical Equation
#### Description:
Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water \((\text{H}_2\text{O})\) and carbon dioxide \((\text{CO}_2)\) chemically react to form the simple sugar glucose \((\text{C}_6\text{H}_{12}\text{O}_6)\) and oxygen gas \((\text{O}_2)\).
#### Problem Statement:
What mass of simple sugar glucose is produced by the reaction of 7.6 g of water?
**Round your answer to 2 significant digits.**
#### Input Field:
A blank input field is provided for the user to enter the mass of glucose in grams.
#### Interactive Elements:
- **x10 Checkbox**: To easily enter values in scientific notation.
- **Action Buttons**:
- **X**: To clear the input.
- **Circular Arrow**: To reset the input.
- **?**: For help or hints.
#### Explanation and Check Buttons:
- **Explanation**: To provide a detailed solution.
- **Check**: To verify the entered answer.
---
This section will help students understand the relationship between reactants and products in photosynthesis and practice stoichiometric calculations by determining the amount of glucose produced from a given mass of water.
![### Atoms, Ions and Molecules: Predicting the Formula of Ionic Compounds with Common Ions
#### Instruction:
Write the empirical formula for at least four ionic compounds that could be formed from the following ions:
MnO<sub>4</sub><sup>−</sup>, Fe<sup>3+</sup>, Pb<sup>4+</sup>, CO<sub>3</sub><sup>2−</sup>
#### Input Box:
- [Example input box for the user to enter the formulas]
#### Toolbar:
- Button 1: An option to add subscripts allowing for chemical notation.
- Button 2: Square brackets for complex ion notation.
- `X` Button: Clear input
- `⟲` Button: Undo last action
- `?` Button: Helps with task
#### Interaction:
- [Explanation Button]: Open a screen with detailed breakdown and examples.
- [Check Button]: Validate the entered formulas and provide feedback.
#### Example:
For example, combining Fe<sup>3+</sup> and CO<sub>3</sub><sup>2−</sup> gives the compound Fe<sub>2</sub>(CO<sub>3</sub>)<sub>3</sub>.
To form four ionic compounds, you can mix different cations and anions from the options provided.
Let's see a step-by-step approach to creating these formulas:
1. Combine MnO<sub>4</sub><sup>−</sup> and Fe<sup>3+</sup>
2. Combine MnO<sub>4</sub><sup>−</sup> and Pb<sup>4+</sup>
3. Combine CO<sub>3</sub><sup>2−</sup> and Fe<sup>3+</sup>
4. Combine CO<sub>3</sub><sup>2−</sup> and Pb<sup>4+</sup>
