Answer:

The mass of 8.250 moles of Cu2O is 1180.5g

Explanation:

HOW TO CALCULATE MASS OF A SUBSTANCE:

Mass (g) = no. of moles (mol) × molar mass (g/mol)

Mass of Cu2O = 8.250 mol × 143.09 g/mol

Mass of Cu2O = 1180.5 g

Therefore, the mass of 8.250 moles of Cu2O is 1180.5 g.

Answer:

It's called the “The Three Sisters” because it comes from an Iroquois legend. The Legend says corn, beans and squash are inseparable sisters that were given to the people by the “Great Spirit.” It is important to note, however, that the “Three sisters” are also found in many other areas and tribes around North America.

The compound with the presence of higher inter-molecular forces has been Acetic acid. Thus, option A is correct.

The boiling point has been the temperature, at which the liquid has been started to convert to steam. The boiling has been mediated with the application of the energy to the substance for the breaking of the inter-molecular forces.

The higher the inter-molecular forces in the compound, the higher will be the boiling point of the compound. The higher concentration has also resulted in a higher boiling point.

In the following compounds, acetic acid has the highest boiling point of 118 degrees Celsius. Thus, it has been constituted of the higher inter-molecular forces. Hence, option A is correct.

The mass of oxygen required for complete utilization of 4 mol of Mg has been 64 g. Thus, option B is correct.

The balanced equation for the reaction has been:

[tex]\rm 2\;Mg\;+\;O_2\;\rightarrow\;2\;MgO[/tex]

From the balanced chemical equation, for complete utilization of 2 moles of Mg, 1 moles of oxygen has been used.

The given moles of Mg has been 4 mol. The moles of oxygen required can be given as:

[tex]\rm 2\;mol\;Mg=1\;mol\;O_2\\4\;mol\;Mg=2\;mol\;O_2[/tex]

Thus, the moles of oxygen required has been 2 mol for complete utilization of 4 mol Mg.

The mass from moles can be calculated as:

[tex]\rm Mass=Moles\;\times\;molecular\;mass[/tex]

The molecular mass of oxygen has been 32 g/mol.

The mass of oxygen has been:

[tex]\rm Mass=2\;\times\;32\;g\\Mass=64\;g[/tex]

Answer:

211.0

Explanation:

∆G(free energy) = ∆H(enthalpy) - T∆S(entropy)

∆H = 215KJ/mol

T = 90°C = 273 + 90

= 363K

∆S = 11J/mol/K or 11 × 10^-3kJ/mol/K

∆G = 215- 363(11 × 10^-3)

= 215 - 3.993

= 211.007

Explanation:

Material properties are dependent on the temperature. The tensile strength, yield strength and modules of elasticity decrease with increasing temperature. It should be expected that fatigue properties are also affected by the temperature.

Answer:

Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

Explanation:

Answer: It is conserved.

Explanation: When the box is pushed across the floor, then floor and box becomes warm which resembles the condition of conservation of energy.

The given problem can be resolved by the concept of energy conservation. The statement of energy conservation says that, "Energy is neither be created nor be destroyed, but it is converted from one form to another.

In the given problem, the person pushes the box across the floor, such that the mechanical energy from the moving arms of person is transferred to the box, and the box and floor becomes warm.

During this process, the energy from the person moving arm is transferred to the box in the form of kinetic energy. And thus kinetic energy is then being transferred to thermal energy or heat energy, due to which the box and floor becomes warm.

Thus, we can conclude that the given case reflects the process of transformation of energy from one state to another, which highlights that during the process, energy is conserved.
