Answer:

V = 0.0496 L

Explanation:

Given that,

The mass of a sample, m = 352.2 g

The density pf sample, d = 7.10 g/mL

We need to find the volume of the sample. We know that the density of an object is given by :

[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{352.2}{7.1}\\\\V=49.6\ mL[/tex]

or

V = 0.0496 L

So, the volume of the sample is 0.0496 L.

Le Châtelier's Principle states that a change in pressure, temperature, or concentration will push the equilibrium to one side of the chemical equation. So, if you manipulate the conditions to favor the product side, you increase the yield and vice versa.

Answer:

Thermal Energy: It refers to some distinct physical concepts, such as the internal energy of a system or heat or sensible heat. And these mode of transfer of heat include, convection, conduction and radiation which I have explained below.

Convection: This is a mode of transfer of heat in which bulk movement of molecules within fluids takes place, as these molecules move the heat obtained by each of the molecules will reach the new location.

Radiation: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium

Conduction: Conduction is the transfer of internal energy by microscopic collisions of particles and the movement of electrons within an object.

Explanation:

Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.

Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth. Therefore, the correct option is option D.

Any large, gaseous celestial body that is capable of producing its own light and illuminates through radiation. Only a very small portion of the tens of milliards of milliards of stars that make up the observable cosmos are readily visible to the eye.

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness. Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

Therefore, the correct option is option D.

Answer:

2 K(s) + Cl₂ (g) --> 2 KCl(s)

Explanation:

Potassium will just be K

Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂

Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl

Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)

Explanation:

Depending on the kind of substance you have (since ur answer of what substances was vauge) you would want to look at the molecular structure of the substances.

Understanding intermolecular bonds are key here (research this)

For example, Bromine is found as Br2 and only exerts London dispersion forces as there is no difference in polarity. And because this force is weaker, it has a lower boiling point

Another example being something like Hydrochloric acid (HCl). This is where Hydrogen acts as the positive atom while chlorine is the negative atom. This creates a stronger force and thus, a higher boiling point than Br2

Finally, there is Something like H2O where the force in play is Hydrogen bonding as Nitrogen, Oxygen, Fluorine where the bonds are strongest due to the electronegativity is at the greatest difference between these and Hydrogen. and thus having a higher boiling point.

So depending on the substance's bond, that will help determine the boiling point. If they fall under the same group, go based on the greatest difference in electronegativity.

I don't know if this is what you're looking for but, hope this helps. :)

Answer:

a. [tex]r_{N_2O_5}=-0.075M/min[/tex]

b. [tex]r_{N_2O_4}=0.075M/min[/tex]

Explanation:

Hello.

In this case, according to the balanced chemical reaction, we can write the law of rate proportions:

[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}[/tex]

Thus, we proceed as follows:

a. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_5}=\frac{r_{O_2}}{-2} =\frac{0.15M/min}{-2}\\\\ r_{N_2O_5}=-0.075M/min[/tex]

b. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

[tex]\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_4}=\frac{r_{O_2}}{2} =\frac{0.15M/min}{2}\\\\ r_{N_2O_4}=0.075M/min[/tex]

56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

A body's mass is an inherent quality. Prior to the discovery of a atom or particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the very same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to acceleration in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

2 Al + 3 Cl[tex]_2[/tex] → 2 Al C l[tex]_3[/tex]

mole of Al =  135.0/ 26=5.19mol

mole of Cl[tex]_2[/tex] = 75.0/ 35 =2.14 mol

mass of aluminum chloride =  56.8g

Limiting reagent = Al

excess reactant =  Cl[tex]_2[/tex]

Therefore, 56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.
