Answer: IM IN LOVE:3
Explanation:
B) C + O = CO2
C) C+ O -> CO2
D) C, O, CO2
The correct option is C.
When writing chemical equations, the chemical symbols of the element are usually used together with numbers to indicate the ratio of each element in the chemical compounds. The additional sign is usually used in between the reactants and the products. The arrow sign in used to show the direction in which the reaction is proceeding. In the correct option given above, the arrow sign is used to indicate that the reaction is moving in the forward direction.
Answer:
C) C+ O -> CO2
Explanation:
I took the test k12
We have that for the Question "how many atoms are in Na2CrO4" it can be said that The total number of atoms is
From the question we are told
how many atoms are in Na2CrO4
Generally
In identifying the atoms are in Na2CrO4 we must first look closely at the compound Na2CrO4
We have
Na=1
Cr=2
O=4
Therefore
The total number of atoms is
X=1+2+4
X=7 atoms

True. The balanced equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O represents the combustion of ethane (C₂H6).
A substance (often a hydrocarbon) combines with oxygen (O₂) in a combustion reaction, resulting in the major byproducts of carbon dioxide (CO₂) and water (H₂O). According to the equation, four molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) are produced when two molecules of ethane (C₂H₆) and seven molecules of oxygen (O₂) react.
The number of atoms in each element is equal on both sides of the reaction arrow, indicating that the equation is balanced. This guarantees that the law of conservation of mass—according to which, in a chemical reaction, mass is never created nor destroyed—is upheld.
In conclusion, the combustion of ethane is accurately represented by the following balanced equation.

2C2H6 + 7O2 → 4CO2 + 6H2O
C2H6 is ethane,
Ethane reacts with oxygen, so it is the combustion.
The equation is balanced.
Answer is True.
Answer:
19.264×atoms are present in 3.2 moles of carbon.
Explanation:
It is known that one mole of each element is composed of Avagadro's number of atoms. This is same for all the elements in the periodic table.
So, as 1 mole of any element = Avagadro's number of atoms = 6.02× atoms
It is as simple as understanding a dozen of anything is equal to 12 pieces of that object.
As here the moles of carbon is given as 3.20 moles, the number of atoms in this mole can be determined as below.
1 mole of carbon = 6.02 × atoms
Then, 3.20 moles of carbon = 3.20 × 6.02 × atoms
Thus, 19.264×atoms are present in 3.2 moles of carbon.
