3.4 For each of the following elements, locate it in the Periodic Table, and indicate whether it is a metal, metalloid, or non-m
1 answer:
According to its location in the periodic table:
- Ge: Period 4, Group 14. Metalloid.
- Se: Period 4, Group 6, Non-metal.
- Be: Period 2, Group 2, Metal.
It is a table in which elements are ordered in Groups (columns) and Periods (rows).
According to their ubication and properties they can be classified in:
- Metals: occupy the left and center of the table.
- Metalloids: occupy the right of the table (dark green in the attached table).
- Non-metals: occupy the right of the table (yellow and light green in the attached image).
Let's locate and classify the following elements:
- Germanium: Period 4, Group 14. Metalloid.
- Selenium: Period 4, Group 6, Non-metal.
- Beryllium: Period 2, Group 2, Metal.

Answer:
Here's what I get
Explanation:
Assume the initial concentrations of H₂ and I₂ are 0.030 and 0.015 mol·L⁻¹, respectively.
We must calculate the initial concentration of HI.
1. We will need a chemical equation with concentrations, so let's gather all the information in one place.
H₂ + I₂ ⇌ 2HI
I/mol·L⁻¹: 0.30 0.15 x
2. Calculate the concentration of HI
3. Plot the initial points
The graph below shows the initial concentrations plotted on the vertical axis.
