Respuesta:

292 g / mol;

Por favor, consulte la explicación.

Explicación:

El número de átomos de cada elemento en el compuesto: Fe2 (co3) 3.

Fe = 2; C = 3; 0 = 3 * 3 = 9

Fe2 = 112 g / mol

C = 12 g / mol

O = 16 g /

Masa molecular = ((112 + (12 * 3) + (16 * 9)

= (112 + 36 + 144)

= 292 g / mol.

Total = 2 + 3 + 9 = 14

Fe2 = 112/292 * 100% = 38,356%

C = 36/292 * 100% = 12,328 * '

O = (16 * 9) / 292 * 100% = 49,32%

Molality = moles of solute/mass (in kg) of solvent

The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.

The solvent here is water, of which you have 1500 g or 1.500 kg H2O.

The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.

If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.

The theoretical yield is 6 sapphire rings.

This is the total product formed as a result of the complete conversion of

the reactants. In this scenario, the reactant is the 12 sapphires in which 2

of it is needed to produce one sapphire ring.

This however translates to the theoretical yield being 6 sapphire rings

which is gotten by:

2 sapphires = 1 ring

12 sapphires = x

Cross multiply

2x = 12

x= 12/2 = 6 sapphire rings.

Answer:

The correct answer would be = 1/32.

Explanation:

The half-life is the time required for a quantity to reduce to half of the initial value of an object or element.

it is given that Fluorine-21 has a half-life time = 12 seconds

then in a minute the number of half-lives,

12 seconds = 12/60 of a minute or 1/5 of a minute

This means in 1 minute we will half the sample 5 times.

(1/2)^5 = 1/32 is the fractional remainder

Thus, the correct answer would be 1/32.

Answer:

E. Cl2 + 2NaBr ----> Br2 + 2NaCl

Explanation:

Number of Cl molecules is 2 on the reactant and product side of the equation.

Number of Na molecules is  2 on the reactant and product side of the equation.

Number of Br molecules is 2 on the reactant and the product side of the equation.

As the reactant side is equal to the product side, the equation is balanced.

Answer:

There were originally 8 atoms of Potassium-40.

Explanation:

The half-life of a radioactive material is the time taken for half the original material to decay or the time required for a quantity of the radioactive substance to reduce to half of its initial value.

If the original material formed without any Argon-40, it means that the atoms originally present were Potassium-40 atoms.

Presently, there are 7 Argon-40 atoms for every 1 of Potassium-40, we can deduce the number of half-lifes the Potassium-40 has undergone as follows :

After one half-life, (1/2) there will be one Potassium-40 atom for every Argon-40 atom.

After a second half life, 1/2 × 1/2 = 1/4: there will be one Potassium-40 atom for every three atoms of Argon-40.

After a third half-life, 1/4 × 1/2 = 1/8: there will be one Potassium-40 atom for every 7 atoms of Argon-40.

Since there are 1/8 atoms of Potassium-40 presently, there were originally 8 atoms of Potassium-40.

Answer:

P₂ = 113.49 kPa

Explanation:

Given that,

Initial pressure, P₁ = 101 kPa

Initial temperature, T₁ = 10.0°C = 283 K

Final temperature, T₂ = 45°C = 318 K

The relation between pressure and temperature is given by :

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

Where

P₂ is the new pressure

So,

[tex]P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{101 \times 318}{283 }\\\\P_2=113.49\ kPa[/tex]

So, the new pressure is equal to 113.49 kPa.

Answer:

17.5moles

Explanation:

The number of moles in a substance can be calculated by using the formula;

Number of moles (n) = mass (m) ÷ molar mass (MM)

According to this question, mass of ammonia (NH3) = 297g

Molar Mass of NH3 = 14 + 1(3)

= 17g/mol

n = 297/17

n = 17.47

Number of moles of NH3 = 17.5moles

Answer:

Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. ... Those are both good examples of convection, the movement of warm particles from warmer to cooler locations, Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.

Explanation:

Hope this helps!

Answer:

thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)

heat is the thermal energy that flows from one substance to another due to a temperature difference.  

Thermal energy is measured in temperature change.

Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).

conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.

convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.

radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.

Answer:

228.4 kPa

Explanation:

From thw question,

PV/T = P'V'/T'..................... Equation 1

Where P = Inital pressure, T = Initial Temperature, V = Initial Volume, P' = fInal Pressure, V' = Final volume, T' = Final Temperature.

Make P' the subject of the equation

P' = PVT'/TV'...................... Equation 2

Given: P = 115 kPa, V = 15.0 dm³, T = 33°C = (33+273) K = 306 K, T' = 51.2°C = 51.2+273 = 324.2 K, V' = 8.00 dm³

Substitute these values into equation 2

P' = (115×15×324.2)/(306×8)

P' = 228.4 kPa.

Answer: a.  [tex]11.9\times 10^{23}atoms[/tex] of carbon

b. [tex]35.7\times 10^{23}atoms[/tex] of hydrogen

c. [tex]5.96\times 10^{23}atoms[/tex] of oxygen

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}=\frac{45.6g}{46.07g/mol}=0.989moles[/tex]

a) 1 mole of ethanol [tex](C_2H_5OH)[/tex] contains = [tex]2\times 6.023\times 10^{23}=12.05\times 10^{23}atoms[/tex] of carbon

Thus 0.989 moles ethanol [tex](C_2H_5OH)[/tex] contains = [tex]\frac{12.05\times 10^{23}}{1}\times 0.989=11.9\times 10^{23}atoms[/tex] of carbon

b) 1 mole of ethanol [tex](C_2H_5OH)[/tex] contains = [tex]6\times 6.023\times 10^{23}=36.14\times 10^{23}atoms[/tex] of hydrogen

Thus 0.989 moles ethanol [tex](C_2H_5OH)[/tex] contains = [tex]\frac{36.14\times 10^{23}}{1}\times 0.989=35.7\times 10^{23}atoms[/tex] of hydrogen

c)  1 mole of ethanol [tex](C_2H_5OH)[/tex] contains = [tex]6.023\times 10^{23}atoms[/tex] of oxygen

Thus 0.989 moles ethanol [tex](C_2H_5OH)[/tex] contains = [tex]\frac{6.023\times 10^{23}}{1}\times 0.989=5.96\times 10^{23}atoms[/tex] of oxygen
