Os H2O an acid or base? Answer it....don\'t google it...

Answer» Then
Haa to acid or bases ko amphoteric n khte h

Bronsted Lowry later was disapproved by others
Mai sahi hu???
Then it is known as amphoteric oxide
It follows bronsted lowry principle
Guys u r fogotting that water can be mixed with bith base ans acid so it is amphoteric
H2o acts both as an acid and base as Kevin said
Acid
How?? Dollon
Because it\'s Ph is 7
Its a base not neutral
Yes naina...u r partially correct
Neutral.
Amphoteric
Source google..
Base
Then??
In this reaction, the water molecule donates a proton to the NO 2 − ion, making OH −(aq). As the proton donor, H 2O acts as a Brønsted-Lowry acid. In this reaction, the water molecule accepts a proton from HC 2H 3O 2, becoming H 3O +(aq). As the proton acceptor, H 2O is a Brønsted-Lowry base.
No guys
It is neutral as its ph value is 7
I think amphoteric oxide
H2O means water is a neutral substance
Base

write stages that occur during photosynthesis

Answer» Dark reaction and light reaction
Photosynthesis: Two StagesWhile the mechanisms of photosynthesis are complex, the overall reaction is as follows: carbon dioxide + sunlight + water --> glucose (sugar) + molecular oxygen (O2). This reaction takes place through several steps which occur during two stages, or phases: the light phase and the dark phase.In the light phase, energy from light, powers reactions that split water to release oxygen. In the process, high energy molecules, called ATP and a reducing agent and NADPH are formed. Actually, it is the the chemical bonds in these compounds that stores the energy. The dark phase is also known as the Calvin Cycle. In this phase, which uses the ATP and NADPH from the light phase, carbcarbon dioxide used to make the sugar, glucose. Oxygen is a byproduct of the reaction.
The three events that occur during the process of photosynthesis are:(i) Absorption of light energy by chlorophyll.(ii)\tConversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.\t(iii)\tReduction of carbon dioxide to carbohydrates.
Light dependent phase and light independent phase
