Write down a balanced chemical equation for a neutralizing reaction of a titration

Chemistry

Balanced chemical equation for a neutralizing reaction:

NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l).

Neutralization is is reaction in which an acid and a base react quantitatively (same omount of substance) with each other.

pH of sodium hydroxide (NaOH) solution is above seven (basic), when solution of hydrochloric acid (HCl) is added, pH slowly dropping until it became neutral solution (pH is equal seven) and that is the endpoint of titration.

Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine an equivalence point.

Caculate the mass of a solid with a density of 14.2 g/cm cubed and a volume of 350 cm cubed​
shepuryov [24]

Answer:

The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.

Explanation:

Formula for density is given below :

density = \frac{mass}{volume}

volume = 350 cm^{3}

density = 14.2 g/cm^{3}

Insert the values in the formula

14.2 = \frac{mass}{350}

on cross multiplication :

mass = density\times volume

mass = 14.2\times 350

mass = 4970 g

1 g = 0.001 Kg

mass =4970\times 0.001 Kg

mass = 4.97 Kg

Note : Check the units of volume and density carefully

What makes a charged object attract an uncharged object?
Ratling [72]

Answer:

its c I think C)

 

The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.

The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.

So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.
