What type of compound does the formula, CuCl2, represent? a. ionic salt b. covalent molecule

1 answer:

7 0

The answer is: [B]: "ionic salt" .
___________________________________________________
Note: There is no "sharing of electrons" among the elements in this compound; so this compound in NOT a "covalent molecule".

However, there is ionic bonding: Cu²⁺ and Cl⁻ ; to form: "CuCl₂" .

How many protons, neutrons, and electrons are in 195Pt2+ ?

ladessa [460]

Answer:

The answer to your question is Protons = 78, Neutrons = 117, Electrons = 76

Explanation:

¹⁹⁵Pt²⁺

Protons are equal to the atomic number, Platinum has an atomic number of 78 so the number of protons = 78.

The number of neutrons = Mass number - Number of protons

= 195 - 78

= 117

The number of electrons is equal to the number of protons - two, we know this because of the 2+ exponent next to the Platinum symbol.

Number of electrons = 78 - 2

= 76

what is the molarity of a solution of hcl if 250 ml of a 0.50 m solution of naoh will completely neutralize 100.ml of this acid

frez [133]

The molarity of the acid is 1.25 M.

<u>Explanation:</u>

We have to find the molarity of HCl by writing the balanced equation that is the neutralization reaction of Hydrochloric acid with the base, Sodium Hydroxide, NaOH.

HCl + NaOH → NaCl + H₂O

From the balanced equation, we can find that one mole of an acid is used to neutralize one mole of a base.

As per the law of volumetric analysis, we can write the equation as,

V1M1 = V2M2

Here V1 and M1 being the volume and molarity of the NaOH

V2 and M2 being the volume and molarity of HCl

V1 = 250 ml

M1 = 0.50 M

V2 = 100 ml

M2 = ?

Now the above equation can be rearranged to find the molarity of the acid as,

M2 = $$\frac{V1M1}{V2}$

= $$\frac{250 ml \times 0.50 M}{100 ml}$

= 1.25 M

So the molarity of the acid is 1.25 M.
