Which of the following shows the equation balanced?
A. 3 O2 + CS2 → CO2 + 2 SO2
B. 3 O2 + CS2 → 2 CO2 + SO2
C. O2 + CS2 → CO2 + SO2
D. 4 O2 + 4 CS2 → 4 CO2 + 4 SO2
Answer:
Look at the equation below.
→
The equation balanced is:
A. →
Explanation:
The equation balanced is:
→
This can be proved with the amount of atoms of each element in reagents and products:
Reagents:
O=6
C=1
S=2
Products:
O=6
C=1
S=2
The option that shows the that the equation is balanced is:
3O₂ + CS₂ → CO₂ + 2SO₂ (option A)
The equation O₂ + CS₂ → CO₂ + SO₂ can be balanced as shown below:
O₂ + CS₂ → CO₂ + SO₂
There are 2 atoms of S on the left side and 1 atom on the right. It can be balanced by writing 2 before SO₂ as shown below:
O₂ + CS₂ → CO₂ + 2SO₂
There are 2 atoms of O on the left side and a total of 6 atoms on the right. It can be balanced by writing 3 before as shown below:
3O₂ + CS₂ → CO₂ + 2SO₂
Now, we can see that the equation is balanced. Thus, the correct answer to the question is 3O₂ + CS₂ → CO₂ + 2SO₂ (option A)

Answer: The correct answer is Option B.
Explanation:
Photosynthesis is defined as a process in which a plat uses carbon dioxide reacts with water in the presence of sunlight to produce glucose as a product, oxygen and water as a byproduct.
The chemical equation for this reaction follows:
By Stoichiometry of the reaction:
6 moles of carbon dioxide reacts with 12 moles of water in the presence of light to produce 1 mole of glucose, 6 moles of oxygen and 6 moles of water.
Hence, the correct answer is Option B.
(1) FeO (3) Fe3O
(2) Fe2O3 (4) Fe3O=
Every organic molecules/compound contains carbon (c).
Some other very abundant are hydrogen, nitrogen, oxygen, phosphorus, and sulfur.
I learned this with the acronym CHNOPS.
C - Carbon
H - Hydrogen
N - Nitrogen
O - Oxygen
P - Phosphorus
S - Sulfur
Hope this helps!
Answer: The elements which are common for all organic molecules is hydrogen and carbon.
Explanation:
Another name for organic molecules are hydrocarbons. This means that the molecules which consist of hydrogen and carbon atoms is an organic compound.
For Example:
are not organic compounds, because in water, carbon is not there and in carbon dioxide, hydrogen is not there. But, is an organic compound because hydrogen and carbon both are present.
Hence, hydrogen and carbon elements are common to all organic molecules.
