Answer:

Potential

Explanation:

Gravitational potential is the energy the object has of it's position of the earth's surface. When the object is lifted, work is done.  When work is done in raising the height of an object, energy is transferred as a gain in the gravitational potential energy of the object.

One method for determine the purity of a sample of titanium ( IV) oxide, an important industrial chemical, is to combine the sam
Tems11 [23]

The reaction between titanium ( IV) oxide and bromine trifluoride to give  liquid bromine , and oxygen is:

3TiO_{2}+4BrF_{3} -->3TiF_{4}+2Br_{2}+3O_{2}

Thus from each three moles of  titanium ( IV) oxide we will get three moles of oxygen molecule

The mass of oxygen obtained = 0.143g

The moles of oxygen obtained

      = \frac{Mass}{Molar mass}=\frac{0.143}{32}=  0.00447mol

So moles of  titanium ( IV) oxide required will be 0.00447mol

the molar mass of  titanium ( IV) oxide is 79.87g/mol

mass of titanium ( IV) oxide used will be = molesXmolarmass=0.00447X79.87=0.357g

This mass of  titanium ( IV) oxide is present in 2.367g of impure sample

the mass percent will be

Mass=\frac{mass titanium ( IV) oxideX100}{mass impure sample}

Masspercent=\frac{0.357X100}{2.367}=15.08

The percentage of titanium ( IV) oxide in impure sample is 15.08% (w/w)

alukav5142 [94]

The question is incomplete, here is the complete question:

A chemist prepares a solution of copper(II) sulfate (CuSO_4) by measuring out 69.2 g of copper(II) sulfate into a 400. mL volumetric flask and filling the flask to the mark with water.

Calculate the concentration in mol/L of the chemist's copper(II) sulfate solution. Round your answer to 3 significant digits.

<u>Answer:</u> The molarity of copper (II) sulfate solution is 1.08 mol/L

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Given mass of copper (II) sulfate = 69.2 g

Molar mass of copper (II) sulfate = 159.6 g/mol

Volume of solution = 400. mL

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{69.2\times 1000}{159.6\times 400}\\\\\text{Molarity of solution}=1.08M

Hence, the molarity of copper (II) sulfate solution is 1.08 mol/L

How many grams of ethanol (density 0.80 g/cm 3) should be added to 5.0 g of chloroform (density 1.5 g/cm 3) if the resulting mix
kaheart [24]

Answer:

9.2 grams of ethanol should be added.

Explanation:

Let the mass of ethanol be x

Density of an ethanol = d_1=0.80 g/cm^3

Volume of the ethanol =V_1=\frac{x}{0.80 g/cm^3}

Mass of chloroform = 5.0 g

Density of an chloroform= d_2=1.5 g/cm^3

Volume of the ethanol =V_2=\frac{5.0 g}{1.5 g/cm^3}=\frac{1}{3}

Mass of the mixture,m  = x + 5.0 g

Density  of the mixture = d=1.2 g/cm^3

Volume of the mixture=V=\frac{m}{1.2 g/cm^3}=\frac{x+5.0 g}{1.2 g/cm^3}

V=V_1+V_2

\frac{x+5.0 g}{1.2 g/cm^3}=V_1+\frac{1}{3}

\frac{x+5.0 g}{1.2 g/cm^3}=\frac{x}{0.80 g/cm^3}+\frac{1}{3}

Solving for x , we get

x = 9.2 g

9.2 grams of ethanol should be added.
