In what way and in what form does sodium react with water? A colourless solution is formed, consisting of strongly alkalic
Is sodium and water a single replacement reaction?
Sodium metal reacts with water to produce hydrogen gas. What best describes this reaction? a. A single replacement reaction takes place because sodium is less reactive than hydroxide ions.
What type of reaction is Na H2O -> NaOH H2?
NaH+H 2 O → NaOH+ H 2 is a type of displacement redox reaction .
What type of reaction is sodium?
Reaction with nonmetals
Halogen acids, such as hydrochloric acid, react vigorously with sodium, yielding the sodium halides. The reactions are highly exothermic , with heats of reaction (energy given off) of −71.8 and −76.2 kcal, respectively, for the reactions with hydrofluoric and hydrochloric acids.
What is the chemical equation when sodium reacts with water?
Sodium + Water → Sodium hydroxide + Hydrogen . (A)- 2Na(s) + 2H2O(l)→2NaOH(aq) + H2(g)
What happens when sodium reacts with water class 8?
Sodium being very reactive reacts vigorously with water leading to the production of sodium hydroxide and hydrogen . Therefore it is stored in kerosene.
How do you know if a reaction is single replacement?
A higher ranked element in the activity series is more reactive in a single replacement reaction. We predict a single replacement reaction will occur when a less reactive element can be replaced by a more reactive element in a compound .
What type of reaction is fecl3 and NaOH?
Type of Chemical Reaction: For this reaction we have a double replacement reaction . Balancing Strategies: This is a double displacement reaction. It is helpful to count the OH- as one thing since you have it on both sides of the equation (see video solution in “Show Balanced Equation”).
What happens when sodium reacts oxygen?
Let’s see the complete reaction when sodium metal reacts with oxygen of the air at room temperature. Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide.
What is the formula of sodium and chlorine?
| Names | show SMILES | Properties | Chemical formula NaCl | Molar mass 58.443 g/mol |
|---|
Why is sodium kept in kerosene?
> Sodium is kept in kerosene because it is a highly reactive metal . If it is kept in an open container, it will react with oxygen and water vapor present in the atmosphere producing sodium oxides and sodium hydroxides respectively which is a highly exothermic reaction.
Will sodium reacts with water?
Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H 2 ). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
What happens when sodium is added to water?
When sodium is added to water, the sodium melts to form a ball that moves around on the surface . It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.
Why does sodium react with water?
The sodium immediately gives up its outermost electron to the aqueous solution that is water, ... then the neutral hydrogen becomes molecular hydrogen gas and rises out of the aqueous solution, and finally, if there’s enough energy, the atmosphere’s oxygen reacts with the hydrogen gas, creating a combustion reaction.
