Answer:
Explanation:
State symbols are used in chemical equations to delineate the state of matter in which the reaction is taking place.
They give a good perspective of the state of the reactants and products obtainable.
There are basically four states of matter in every chemical reaction:
- Solids are symbolized by small letter (s)
- Liquids are represented by (l)
- Gases are shown by (g)
- Aqueous solutions having water as the medium by (aq)
These symbols appear as subscript in front of the chemical species.
Answer:
gravity that's what I rellat think it is
Answer : The number of moles of oxygen needed are, 1.5 moles.
Explanation :
The balanced chemical reaction will be:
Now we have to calculate the moles of oxygen.
From the balanced chemical reaction we conclude that,
As, 6 moles of water vapor produces from 5 moles of oxygen
So, 1.80 moles of water vapor produces from 
moles of oxygen
Therefore, the number of moles of oxygen needed are, 1.5 moles.
Answer: Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by the wind. These pollutants cause acid rain.
