Answer: It is either reflected or transmitted.
Explanation:
The color of the objects is due to the light reflected to our eyes.The light falls on the surface of the object and the color which does not get absorbed by the object gets transmitted or reflected and thus appear to be of the same color as the reflected or transmitted light.
Example: If an object absorbs all of the frequencies of visible light except for the frequency associated with green light, then the object will appear green in color.
(2) the activation energy of the exothermic reaction
(3) the difference between the potential energy of the products and the potential energy of the reactants
(4) the sum of the potential energy of the products and the potential energy of the reactants
Answer: The correct answer is Option 3.
Explanation:
The net energy absorbed or released in a chemical reaction is known as the total enthalpy change of the reaction. It is written as
The formula used to calculate total enthalpy of the reaction is:
where,
= Potential energy of the products
= Potential energy of the reactants
Hence, the correct answer is Option 3.
(2) decrease and the volume of the gas sample to increase
(3) increase and the volume of the gas sample to decrease
(4) increase and the volume of the gas sample to increase

c. 18
d. 19
Answer:
The complete photosynthesis equation is:
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2
This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O), in the presence of light energy, react to produce glucose (C6H12O6) and oxygen (O2).
The photosynthesis equation is: 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen.
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. The equation for photosynthesis is:
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
In this equation, carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy.
During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The process takes place in the chloroplasts of plant cells, specifically in the chlorophyll-containing organelles called chloroplasts. Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen.

Answer: Option (D) is the correct answer.
Explanation:
It is known that relation between pressure and force is that, pressure equals force divided by area.
Mathematically, P =
where P = pressure
F = force
a = area
Hence, when there is increase in number of gas particles in a container the there will be more number of collisions due to increase in number of particles. This will lead to greater collision force and as a result there will be increase in pressure because force is directly proportional to pressure.
Thus, we can conclude that the sequence more collisions --> greater collision force --> higher pressure best describes the result of increasing the number of gas particles in a container best describes the result of increasing the number of gas particles in a container.
