Answer:
Option C = 150
Explanation:
First of all we will understand what is law of conservation of mass.
Law of conservation of mass:
This law stated that, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six number of carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of chemical equation so this reaction followed the law of conservation of mass because mases are same on both side.
In given chemical reaction:
AB + CD → X
50 g + 100 g = 150 g
Thus option c is correct.
The field of study which is shown in the picture is known as archaeology and is denoted as option D.
<h3>What is Archaeology?</h3>
This is defined as the scientific study of the material remains of past human life and activities through gathering of fossils.
This is usually done by a professional referred to as an archaeologist who uses special techniques and methods in the execution of the processes involved.
In the diagram attached in the picture shown below, we can view rocks present which helps to preserve fossils.This is therefore the reason why archaeology was chosen as the most appropriate choice.

<u>Answer:</u> The electronic configuration of the elements are written below.
<u>Explanation:</u>
Electronic configuration is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom is determined by the atomic number of that atom.
For the given options:
- <u>Option a:</u> Carbon (C)
Carbon is the 6th element of the periodic table. The number of electrons in carbon atom are 6.
The electronic configuration of carbon is 
- <u>Option b:</u> Phosphorus (P)
Phosphorus is the 15th element of the periodic table. The number of electrons in phosphorus atom are 15.
The electronic configuration of phosphorus is 
- <u>Option c:</u> Vanadium (V)
Vanadium is the 23rd element of the periodic table. The number of electrons in vanadium atom are 23.
The electronic configuration of vanadium is 
- <u>Option d:</u> Antimony (Sb)
Antimony is the 51st element of the periodic table. The number of electrons in antimony atom are 51.
The electronic configuration of antimony is 
- <u>Option e:</u> Samarium (Sm)
Samarium is the 62nd element of the periodic table. The number of electrons in samarium atom are 62.
The electronic configuration of samarium is 
Hence, the electronic configuration of the elements are written above.
This is pretty easy lol.... AS and AR
Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.
