B. A body at rest will stay at rest until it is acted upon by another object

Explanation:

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

The true statement concerning visible light and electromagnetic radiation is considered to be - d. Visible light is a small portion of the electromagnetic spectrum.

The electromagnetic spectrum is the range of frequencies of electromagnetic waves or radiations. This spectrum also gives an idea about the wavelengths of electromagnetic radiations. The part of the spectrum on their higher to lower energy or frequency range from  Hz to  Hz are:

gamma rays

X-rays

ultraviolet radiation

visible light

infrared radiation

radio waves.

The visible light is the very small part of the electromagnetic spectrum that ranges from the to, Visible light is the light that the human eye can see.

The final pressure in the container if the temperature remains constant is 68.3 kPa.

Given the following data;

To find the final pressure in the container if the temperature remains constant, we would use Boyle's Law:

Mathematically, Boyle's law is given by the formula;

[tex]P_1V_1 = P_2V_2[/tex]

Where;

Substituting the values into the formula, we have;

[tex]205[/tex] × [tex]4 =[/tex] [tex]12P_2[/tex]

[tex]820 = 12P_2\\\\P_2 = \frac{820}{12}[/tex]

Final pressure, P2 = 68.3 kPa

Therefore, the final pressure in the container if the temperature remains constant is 68.3 kPa.

In the combustion of 28.0 g of gasoline, 1348.1 kilojoules of energy are released.          

To find the energy released, we need to convert the energy in kilocalories to kilojoules.

We need to remember that:

Hence, the energy in kJ is:

[tex] E = 322 \:kcal*\frac{4.1868 \:J}{1 \:cal}*\frac{1000 \:cal}{1 \:kcal}*\frac{1 \:kJ}{1000 \:J} = 1348.1 \:kJ [/tex]

Respuesta:

Las fuerzas intermoleculares que actúan entre las moléculas se clasifican en : Dipolos permanentes. Dipolos inducidos. Dipolos dispersos.

Explicación:

Dentro de una molécula, los átomos están unidos mediante fuerzas intramoleculares (enlaces iónicos, metálicos o covalentes, principalmente). Estas son las fuerzas que se deben vencer para que se produzca un cambio químico. Son estas fuerzas, por tanto, las que determinan las propiedades químicas de las sustancias.

Sin embargo existen otras fuerzas intermoleculares que actúan sobre distintas moléculas o iones y que hacen que éstos se atraigan o se repelan. Estas fuerzas son las que determinan las propiedades físicas de las sustancias como, por ejemplo, el estado de agregación, el punto de fusión y de ebullición, la solubilidad, la tensión superficial, la densidad, etc.

Answer:

See below

Explanation:

2C2H6 + 7O2 = 4CO2 + 6H2O

2C2H2 + 5O2 = 4CO2 + 2H2O

A lot of this is trial and error.  I start from left to right.  For the first reaction, you had

C2H6 + O2  =  CO2  +  H2O

You have 2 carbons on the left so you can try adding a 2 in front of the carbons on the right and keep going from there.  Now you have

C2H6  +  O2  =  2CO2  + H2O

You now have 2 C on each side.  C2 is the same as 2C.

The next step is to look at the hydrogens on the left.  You have 6 so you need 6 on the right.  You can add a 3 in front of the H on the right.  The H already has a subscript of a 2 so having the 3 in front will now make it 6H.  You now have this

C2H6  +  O2  =  2CO2  +  3H2O

So your C are equal (2 on each side) and your H is equal (6 on each side).  All that is left is the O.  So far you have 2 on the left but you have 7 on the right (4 from the 2CO2 and 3 more from 3H2O).  Since you have an even number on one side and an odd number on the other, there is no way to make this work.  So it's time to start over.

My next step was to put a 2 in front of C2H6 and keep going as we did above.  Start with this

2C2H6   + O2  = CO2  + H2O

You have 4 C on the left.  So you need to add a 4 in front of CO2 to get 4 C on the right.  Now you have this

2C2H6  +  O2  =  4CO2  +  H2O

Now on the left you have 12 H (2 in front times the 6 subscript on the H).  You need to have 12 on the right.  We can get that by putting a 6 in front of the H2O ( again the 6 in front times the 2 subscript of the H is 12 total).  You have this now

2C2H6  +  O2  = 4CO2  +  6H2O

You now have 4 C on both sides, 12 H on both sides.  All that is left now is the O.

On the right side, you have a total of 14 ( 8 from the 4CO2 and 6 from 6H2O).  So you'd need to add 7 in front of the O2 to make it 14.

You're done.  4 C on both sides, 12 H on both sides and 14 O on both sides.

Answer:

About 10.2 g Li₃N.

Explanation:

We are given the reaction:

[tex]\displaystyle \text{6 Li(s) + N$_2$(g) }\longrightarrow \text{2 Li$_3$N(s)}[/tex]

And we want to determine the amount of Li₃N that can be formed from 6.07 g of Li and an excess of nitrogen.

To convert from g Li to g Li₃N, we can: (1) convert from g Li to mol Li, (2) mol Li to mol Li₃N, and (3) mol Li₃N to g Li₃N.

Molecular weight of Li₃N:

[tex]\displaystyle \begin{aligned}\text{MW}_\text{Li$_3$N} & = (3 (6.94) + 14.01) \text{ g/mol} \\ \\ & =34.83\text{ g/mol} \end{aligned}[/tex]

This yields three ratios:

[tex]\displaystyle \frac{1 \text{ mol Li}}{6.94 \text{ g Li}}, \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}}, \text{ and } \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}}[/tex]

From the initial value, multiply:

[tex]\displaystyle 6.07 \text{ g Li} \cdot \frac{ 1 \text{ mol Li}}{6.94 \text{ g Li}} \cdot \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}} \cdot \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}} = 10.2\text{ g Li$_3$N}[/tex]

In conclusion, 10.2 g of Li₃N is formed from 6.07 g of Li and an excess of nitrogen.

Answer: a) sp and sp hybrid orbitals:

180 degrees

(b) sp and sp hybrid orbitals:

es

120 degrees

(c) sp and sp2 hybrid orbitals:

109.5 degrees

Explanation:

The angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Hybrid orbitals are defined as the outcome of a model that generates a new set of orbitals by combining atomic orbitals on a single atom.

It can also be defined as a form of atomic orbital that emerges when two or more atomic orbitals of an isolated atom mix.

It can be defined as the forming new atomic orbitals by combining two or more common atomic orbitals.

The process which forms hybrid orbitals are known as hybridization.

There are mainly five types of hybridization.

Thus, the angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Explanation:

Water has three states of matter namely gas, solid or ice form and liquid. Molecules in solid state are not able to move since they are tightly packed.

Molecules can move in liquid state and they moves easily in gaseous state.

Every substance have three states, that are gas, liquid and solid. In solid state, molecules are tightly packed and are unable to move apart. In liquid state, molecules have some space to move and motion of liquid is easy.

The movement of molecules in a substance depends on the space allotted for them or called the volume. More volume between molecules, easy to move apart.

Gaseous state is composed of molecules located far apart from each other and they diffuse easily. Therefore, motion in three states of water is different and moves faster in gaseous state.
