Answer: solid.
Explanation:
Precipitate is the solid substance produced during a chemical reaction carried out in a solution.
The precipitate is formed when the reactants in a chemical reaction, which are in solution, form a compound that is insoluble, and so it cannot stand dissolved but precipiates, normally going to the bottom of the vessel, in solid form.
The phases in a chemical equation are indicated using letters inside parenthesis placed to the right of the chemical formula of each compound or element.
These are the common uses: s for solid, aq for aqueous solution, l for liquid, and g for gaseous.
This is an example:
2 NaOH (aq) + CuCl₂ (aq) → 2 NaCl (aq) + Cu (OH)₂ (s)
The phases are:
- Reactant side: NaOH and CuCl₂ are dissolved in water, which is indicated by the the word aq, meaning aqueous.
- Product side: NaCl is aqueous, and Cu(OH)₂ is in solid form, meaning that it is a precipitate.
Answer:
Second step
(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)
Explanation:
This reaction involves;
First the ionization of the tertiary halide to firm a carbocation
Secondly the attack of the hydroxide ion on the carbocation to form tert-butanol
First step;
(CH3)3CBr (aq) → (CH3)3C+ (aq) + Br- (aq)
Second step
(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)
This second step completes the reaction mechanism.
Answer:
Chemical energies
Explanation:
We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy - this is one way of making electricity, see Electricity for more information.
Answer:
a
Explanation:
In logic and philosophy, a property is a characteristic of an object; a red object is said to have the property of redness. The property may be considered a form of object in its own right, able to possess other properties.
i just cant understand the question
