The main difference between gas pressure and vapour pressure is that gas pressure is exerted by the gases above the surface of a substance whereas vapour pressure is exerted by liquids above the surface of a substance
Answer:
2.5 mL
Explanation:
Step 1: Given data
- Concentration of the active ingredient (C): 5% v/v
- Volume of the medicine (V): 50 mL
Step 2: Calculate the amount of the active ingredient in the medicine
The concentration of the active ingredient is 5% v/v, that is, there are 5 mL of the active ingredient per 100 mL of the medicine. The volume of the active ingredient is 50 mL of the medicine is:
50 mL Med × 5 mL AI/100 mL Med = 2.5 mL AI
A suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation about a question that emerged by observing form the real world.
In this case, the dependent variable is the rate of chemical modification because this variable is modified in the experiment.
In conclusion, a suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.

Answer:
d. carboxyl
Explanation:
The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.
For example:
- Formic acid or Methanoic acid (H-COOH)
- Butanoic acid (C3H7-COOH)
Hence, the correct option is "d. carboxyl ".
Step 1-Light Dependent
CO2 and H2O enter the leaf
Step 2- Light Dependent
Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2
Step 3- Light Dependent
The electrons move down to enzymes
Step 4-Light Dependent
Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-Light independent
The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.
Step 6-Light independent
The calvin cycle converts 3CO2 molecules from the atmosphere to glucose
calvin cycle
The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
