The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.
<u>Explanation:</u>
Step 1:
All the sides of the cubes are equal.
Step 2:
Given,
a= 3 cm
Step 3:
Volume of the cube = a³
= 3 × 3 × 3
= 27 cm³
Hence, The volume of the cube is 27 cm³

<u>The objects that allow humans to access ground water are:</u>
- <u>A spring</u>
- <u>a well drilled into an aquifer
</u>
- <u>a well drilled below the water table</u>
<h2>Explanation:</h2>
Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
During normal breathing, the brain is stimulated to breath with increasing acidity as a result of CO2 concentration from basic metabolic processes. The brain is quite selfish and only really wants to maintain it's pH which should be at a range of 7.3-7.45, and will not tolerate any decrease.
In patients who have a chronic respiratory disorder with things like COPD. The brain has become accustomed to excessive acidic content, and is now stimulated by the Hypoxic drive or by low oxygen content.
6CO2 + 6H2O --> C6H12O6 + 6O2
carbon dioxide + water --> glucose + oxygen
