The formula for a lutetium carbonate compound is Lu2(CO3)3. What would be the formula for a lutetium nitrate compound given that

the charge of lutetium is the same in both compounds

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.

What causes the output work of a machine to be less than the input work?????
melisa1 [442]

Inefficiency of the material or engine causes the output work of a machine to be less than the input work. It is governed by the second law of thermodynamics wherein no product of work can produce 100 percent efficiency. Only the Carnot engine can produce a 100 percent effieciency.

What volume of 0.200 M ethanol solution contains each of the following amounts?
Papessa [141]

Answer:

A. 2.3 L

B. 6.10 L

C. 0.060 L

Explanation:

The question asks the volume of a 0.200 M solution of ethanol that contains certain number of moles of ethanol.

The M in the 0.200 M stands for Molarity. This is a unit of concentration that can be expressed as:

Molarity = moles of solute / Liters of solution

In this case:

0.200 M = moles of ethanol / Liters of solution

So from the formula we can get that we can calculate the volume of the solution, as Liters of solution, given the moles in each case as:

Liters of solution = moles of ethanol / 0.200 moles/L

_______________________________________________

A. <u>0.45 mol ethanol</u>

Liters of solution = 0.45 moles / 0.200 moles/L = 2.25 L = 2.3 L

B. <u>1.22 mol ethanol</u>

Liters of solution = 1.22 moles / 0.200 moles/L = 6.10 L

C.<u> </u><u>1.2 x 10⁻² mol ethanol</u>

Liters of solution = 1.2 x 10⁻² moles / 0.200 moles/L = 0.060 L

_______________________________________________

Note: Each answer is given with the correct number of significant figures which results from the least number of significant figures in the given used values in each calculation.

A sample of Element X is found to contain 67.25% of isotope type 1 (85.91) and 32.75% of isotope type 2 (87.91). Calculate the a
KengaRu [80]

Answer:

The average atomic mass is 86.565

Explanation:

An element's average atomic mass is the sum of the products of the masses of the isotopes of the element and their percentage abundance divided by 100

The average atomic mass of the Element X is given as follows;

Isotope type 1 (85.91) ×

Isotope {}   Abundance (%)        Mass         /100        Portion of average mass

Type 1 {}             67.25       ×       85.91      ÷  100        57.774475

Type 2 {}            32.75       ×       87.91       ÷  100       28.790525

{}                                 Average atomic mass         =  86.565

The average atomic mass = 86.565.
