What type of reaction is sodium and water?
Reaction of sodium with water Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
What is the dark reaction?
Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.

What is reaction time?
Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual.
What’s a reaction?
A reaction is an action taken in response to something. If you’re telling your parents that you want to move out, you’ll see by their reaction that they’re sad about it. A chemical reaction describes the way a chemical behaves when combined with another substance.

Which field of chemistry is best?
Which field of Chemistry is best? Biochemistry is among the most preferred branch for studies as well as for career opportunities.
What is a reactant?
The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
What is a physical reaction?
A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. The molecules are not chemically altered. So, the difference is that with a physical reaction, a chemical change in the molecule is not observed, but a physical change is observed.
