Question

Tabht 9 shows observations made when lithium, potassium and rubidium react with water. Table 2 Element & }(c) Observations Lithium Sodium & Bubbles slowly Floats Moves slowly Potassium & Bubbles very quickly Melts into a ball Floats Moves very quickly Flame Rubidium & Sinks Melts into a ball Explodes with a flame (d) Give two observations you could make when sodium reacts with water. Write your answers in Table 2. (2)

Answer 1

Given the experiment results with similar elements (Lithium and Potassium), it's reasonable to make the following predictions: Sodium is expected to behave similar to these Alkali metals when reacting with water due to sharing the same group elements features on the periodic table.For (d) two observations that might be made when Sodium reacts with water:- Sodium is likely to produce bubbles when reacting with water, indicating that a gas is being produced.- Sodium is expected to move or float, indicating a vigorous reaction with water. For the table portion, it can be filled in as:Element | Observations --- | --- Sodium | Produces bubbles; Floats/MovesPlease note: These are educated predictions, the exact reactions may vary depending on the specific conditions and quantity of Sodium used in an actual experiment.

Answer 2

## Step 1:Understanding the provided problem, we see that the question is asking us to predict the result of an experiment involving a reaction between Sodium (an alkali metal) and water.
