Answer:

The answer to your question is Cu(NO₃)₂

Explanation:

To write the chemical formula of a molecule:

1.- Look for the symbols of the elements

Copper = Cu has an oxidation number of +2.

Nitrate = NO₃⁻¹ nitrate is a polyatomic ion so it is composed of nitrogen,

oxygen and its oxidation number is -1.

2.- Write the chemical formula and interchange the oxidation numbers.

Cu⁺² + NO₃⁻¹ ⇒ Cu(NO₃)₂

Fittoniya [83]

Answer:

was difficult to place isotopes of elements as they have the same chemical properties but different atomic masses. It was not possible to predict how many elements could be discovered between two heavy elements as the rise in atomic mass is not uniform.

What is the isotope notation for an ion of silver-109 with a charge of positive 1

Arisa [49]

Answer:

The isotope notation for an ion of silver-109 with a charge of positive 1 is $_{47}^{109}Ag^{1+}$ .

Explanation:

The elements with same atomic number with different mass numbers are called isotopes.

The isotopes of silver is as follows.

$_{47}^{109}Ag,_{47}^{107}Ag$

From the above two isotopes have same atomic number and different mass number.

From the given,the isotope notation for an ion of silver-109 with a charge of positive 1

It can be represented is as follows.

$_{47}^{109}Ag^{1+}$

General representation of isotope is as in attachment.

What is the concentration created when 380.0g of Pb(NO3)2 is added to 330.0 mL of solution?

Juliette [100K]

The concentration of lead nitrate is 3.48 M.

Explanation:

The molarity can be found by dividing moles of sucrose by its volume in litres. We can find the number of moles of sucrose by dividing the given mass by its molar mass. Now we can find the moles as,

Here mass of Pb(NO₃)₂ is 380 g

Molar mass of Pb(NO₃)₂ is 331.2 g/mol

Number of moles = $$\frac{given mass}{molar mass}$

= $$ \frac{380 g }{331.2 g/mol}$

= 1.15 moles

Volume in Litres = 330 ml = 0.33 L

Molarity = $$\frac{Moles}{Volume (L)}$

= 3.48 mol/L or 3.48 M

So the concentration of lead nitrate is 3.48 M.
