Lu(NO₃)₃ would be the formula for a lutetium nitrate compound, given that the charge of lutetium is the same in both compounds.

From Lu2(CO₃)₃, we can determine the charge of the variable charge transition metal Lu has a charge of 3, as CO₃ has a 2⁻ charge (3⁻² = 6⁻¹, 6/2 = 3). Then, we apply this to nitrate, which has a charge of 1⁻. Balance charges, reduce, and you get Lu(NO₃)₃.

<h3><u>Nitrates:</u></h3>

With the chemical formula NO⁻₃, nitrate is a polyatomic ion. This ion is found in salts, which are known as nitrates. Fertilizers and explosives frequently contain nitrates as a component. Nearly all inorganic nitrates are water soluble. Bismuth oxynitrate is an illustration of an insoluble nitrate.

Natural compounds called nitrates (or nitrites) can be found in the soil, air, and water. In order to prevent the growth of germs and to improve the flavor and color of food, nitrates are also employed as a food additive.

- Standard state refers to
yulyashka [42]

Answer: The standard state refers to 1 atm and 25^{o}C.

Explanation:

It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.

So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of 25^{o}C then it known as standard state of substance.

Thus, we can conclude that standard state refers to 1 atm and 25^{o}C.

A compound has an empirical formula of AB and a molar mass of 90 g/mol. What is its
Lelu [443]

Answer:

A3B3

Explanation:

Molecular formula = n x empirical formula

(AB) n = 90

MM of AB = 30 g/mol

30n = 90

Divide both side by the coefficient n i.e 30

n = 90/30 = 3

Molecular formula = n x empirical formula

Molecular formula = n x (AB)

Molecular formula = 3(AB) = A3B3

13. How many moles of sodium hydroxide are needed to neutralize 50grams of sulfuric acid?
Phoenix [80]

Answer:

1.02mole

Explanation:

The reaction equation is given as:

     2NaOH  +  H₂SO₄ →  Na₂SO₄  + 2H₂O

Given:

Mass of H₂SO₄  = 50g

Unknown:

Number of moles of NaOH = ?

Solution:

To solve this problem, we first find the number of moles of the acid given;

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

Molar mass of H₂SO₄ = 2(1) + 32 + 4(16)  = 98g/mol

Now;

   Number of moles = \frac{50}{98}   = 0.51mole

From the balanced reaction equation:

       1 mole of H₂SO₄ will be neutralized by 2 mole of NaOH

     0.51 mole of H₂SO₄ will be neutralized by 2 x 0.51  = 1.02mole of NaOH
