This is true, vapor is just evaporated water. Like in machines, you have to fill it up with water so your machine can produce the water vapor. Hope this helps!!
127.88 grams of ethanol were present at the beginning of the reaction
Explanation:
Firstly, let's make the combustion reaction:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
By 1 mol of ethanol, you can make 3 mole of water.
Mole of water = Water mass / Molar mass
150g / 18g/m = 8.3 mole
3 mole of water came from 1 mol of ethanol
8.3 mole came from (8.3 .1)/3 = 2.78 mole of ethanol
Molar mass ethanol = 46 g/m
Mole . molar mass = mass
2.78 m . 46g/m = 127.88 g
Answer:
on the right side, because it is a product
Explanation:
photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.
_______________________________________________
The general standard for writing chemical reaction is that
- The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
- The output of chemical reaction are written on right side. They are termed as product.
- Transition of reactant to product is shown by arrow.
Chemical reaction for photosynthesis is given by below equation
6CO2 + 12H2O + light ----------------> C6H12O6 + 6O2 + 6H2O
We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.
As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.
.
Thus, of the options given below for
In an equation for photosynthesis does oxygen belong
on the right side, because it is a product
