Volume of alcohol = 4 mL of alcohol
Volume of water required = 194 mL
<h3>What is a dilution factor?</h3>
A dilution factor is a ratio of the solute to solvent. It is used to express how much of the original stock solution is present in the total solution.
Given the following dilution to make:
obtain 200 ml of an isopropyl solution using the dilution ratio 1 : 20 of alcohol to water.
Total volume = 200 ml
Volume ratio of alcohol to solution will be 1/50 * 200
Volume of alcohol = 4 mL of alcohol
Then volume of water required = 200 m - 4 ml
volume of water required = 194 mL
In conclusion, the dilution is done using the dilution factor.

Explanation:
During an algal bloom the species produce a toxic chemical substance which is harmful to animals that feed on the algae that causes a tint in the water because of the photosynthetic pigments is known as a red tide a red tide may or may not be harmful . Nonetheless algal bloom can produce both beneficial and harmful cycles.
It is beneficial because it can provide organic compounds needed by higher organisms, for this reason productivity increases because there's more algae in the water which means that more carbon dioxide is used from the atmosphere and that more oxygen is being released into the atmosphere which is needed and necessary for many living things

Explanation:
Monday is the best day since there is no wind. To conduct canopy fogging, the ideal conditions would be windless and calm, so as not to disrupt the fogging operation.
<h3>What is canopy fogging?</h3>
During fogging, a petrol-powered fogging machine is used to disseminate a non-hazardous natural pyrethroid pesticide into the forest canopy.
The missing image of the question is attached below.
As per the image description, Monday is the best day since there is no wind. To conduct canopy fogging, the ideal conditions would be windless and calm, so as not to disrupt the fogging operation.
Thus, Rachel should conduct canopy fogging on Monday according to the given scenario.
