Answer:
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis.
Explanation:
Definition: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:
The answer to your question is: letter B.
Explanation:
Carbon atom double-bonded to an oxygen atom C= O,
a) Carbohydrate group this group does not exist
b)Carbonyl group This option is right, carbonyl group is C=O
c) Hydroxyl group This option is incorrect, hydroxyl group is OH, very different from C=O
d) Ketone group Ketone group does not exist, ketones have the same functional group as aldehydes (C=O)

Specific heat describes how much heat a substance takes to raise the temperature. Hence, Option (c) is correct
<h3>
What is Specific Heat ?</h3>
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.
The specific heat capacity of a material is a physical property.
It is also an example of an extensive property since its value is proportional to the size of the system being examined.

Answer:
1.32 x 10²⁴
Explanation:
Given parameters:
Volume of carbon tetrachloride = 49.3L
Unknown:
Number of atoms at STP = ?
Solution:
To solve this problem;
At STP;
1 mole of a substance occupies 22.4L ;
So;
Let us find the number of moles;
22.4L = 1 mole
49.3L will give 
= 2.2mole
So;
1 mole of substance contains 6.02 x 10²³ atoms
2.2 mole of Carbon tetrachloride = 2.2 x 6.02 x 10²³ = 1.32 x 10²⁴
