Answer: Chemical equation
Explanation: In writing a chemical equation, the correct formula and symbols of the reactants are written on the left hand side of the equation while those of the products are written on the right hand side. A horizontal arrow is drawn between the two sides to indicate the direction of the reaction.
Example: Na + Cl -> NaCl

Explanation:
Chromatography is a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. The mobile phase is the phase that moves in a definite direction
You must use 134 g O₂ to produce 118 g H₂O.
M_r: 32.00 18.02
2H₂ + O₂ ⟶ 2H₂O
Moles of H₂O = 150.9 g H₂O × (1 mol H₂O/18.02 g H₂O) = 8.374 mol H₂O
Moles of O₂ = 8.374 mol H₂O × (1 mol O₂/2 mol H₂O) = 4.187 mol O₂
Mass of O₂ = 4.1877 mol O₂ × (32.00 g O₂/1 mol O₂) = 134 g O₂
For this problem, we will use the formula setup for Molarity.
The formula is M= moles
---------
liters
So, lets plug in the numbers we have. We know M= 0.954, and L (liters)= 3.63. Lets plug that into our equation.
x
0.954= -----
3.63
As we can see, our moles are unknown.
So, lets multiply 0.954 times 3.63 to get our moles.
0.954 x 3.63 equals 3.46302.
We know this is our correct answer, because when we divide 3.46302 and 3.63, we get 0.954.
Why?
Because when we divide the moles by liters, we get the molarity.
I hope I helped!!!!!
Here are some common units to know if my units confused you.
M= Molarity, which is what we find by dividing moles by liters
mol= Moles
L= Liters
