Answer:
Ionic equation:
Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) → H₂O(l) + Na⁺(aq) + Cl⁻ (aq)
Explanation:
Chemical equation:
NaOH(aq) + HCl(aq) → H₂O(l) + NaCl (aq)
Balanced chemical equation:
NaOH(aq) + HCl(aq) → H₂O(l) + NaCl (aq)
Ionic equation:
Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) → H₂O(l) + Na⁺(aq) + Cl⁻ (aq)
Net ionic equation:
OH⁻(aq) + H⁺(aq) → H₂O(l)
The Cl⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
Hello, there!
In order to solve problems like this DO PEMDAS

So, equals 4
Your problem becomes
Now we have to do what is in the (
( the is a )
And
Problem becomes
So, this means that your answer would be
Good luck on your assignment and enjoy your day!
kjExplanation:
Answer:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
Explanation:
Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants
Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.
The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.
A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.
A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.
According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.
A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.
From the information provided;
Number of moles of acid = 0.002 moles
Volume of solution= 2 L
Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M
pH = - log[H^+]
pH = - log[0.001 ]
pH = 3
From;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 8.5
pOH = 5.5
pOH = - log[OH^-]
[OH^-] = Antilog[-5.5]
[OH^-] = 3.2 × 10^-6 M

The phase in which water molecules form crystal lattice is : B. Freezing
When water undergone a freezing phase, it will trapped a specific amount of Gases inside it. Crystal lattice is basically the gas molecule that trapped within the water
