Answer 2

The type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.

What are bonds?

Bonds are defined as any of the interactions that lead to atoms joining together to form molecules, ions, crystals, and other stable species that make up the familiar materials found in everyday life. The ability to build molecules is made possible by a chemical bond, which is a strong attraction between atoms, ions, or molecules. Chemical bonds that hold molecules together also form temporary connections vital for life.

Covalent bond are defined as a type of chemical link where atoms share electrons to create electron pairs. Low melting and boiling temperatures, low vaporization heat, low water solubility, and poor conductivity are four characteristics of covalent compounds.

Thus, the type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.

Answers

Answer:

Ok, so the process here is to convert the mass of H2 (hydrogen gas) to moles by dividing the mass by the molar mass of H2. Once you have the moles then you have to multiply by the STP (standard temperature and pressure) molar volume which should be 22.4.

Molar mass of H2 = (1.01)x2 = 2.02g/mol

19.3/2.02 = 9.55 moles

Now just multiply the moles by the molar volume

9.55 moles x 22.4 = 213.92 Litres of H2 are in 19.3g of H2

Tom pushes on a 50-kilogram box with a force of 25 newtons. Assuming the surface on which the box moves is frictionless, at what rate does the box accelerate?

Answers

Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 [tex]m/s^2[/tex].

Given the following data:

Mass of box = 50 kilogramForce = 25 newtons.

To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:

Mathematically, Newton's Second Law of Motion is given by the formula;

[tex]Force = mass \times acceleration[/tex]

Making acceleration the subject of formula, we have:

[tex]Acceleration =\frac{Force}{mass}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Acceleration = \frac{25}{50}[/tex]

Acceleration = 0.5 [tex]m/s^2[/tex]

Calculating Heat during Phase Changes

question below in photo :)

Answers

Answer:

Q1= 9.42

Q2= 227 KJ

Q3= 31.4 KJ

Qt=269 KJ

Explanation:

First you have to find the heat needed to make ice at a temperature of -45 C to pass to a temperature of 0 C.

You're given the formula so all you have to do is replace by the data you're given (remember to make the Celsius, Kelvin by adding 273.15 to the Celsius since the magnitudes of temperature they're giving you in the constants are the Kelvin)

Q1= (2.093 J/gxK)(100 g)(45 K)

Q1=9418.5 J

Q1=9.4185 KJ≈9.42 Kj(you're asked to give your answer in KJ)

You know have to find the energy needed to liquify the ice, in other words you need to use the enthalpy of fusion to determine the energy that's being used, and since you have 100 grams of water, you only need to find the number of moles present in 100 grams of water by dividing the number of grams by the molar mass of water (18 g/mol) and then replace in the equation.

Q2=(5.56 mol)(40.7 KJ/mol)

Q2=227 KJ

You know have to find the energy needed to raise the temperature of water from 0 C to 75 C. You do the same thing as you did in the first step:

Q3=(4.184 J/gxK)(100 g/)(75K)

Q3=31380 J

Q3=31.38 KJ≈31.4 KJ

For the final step, you only add the Qs of each step:

9.42KJ+227KJ+31.4KJ= 267.82 KJ ≈ 267.8 KJ

Why do you use these procedures?

Well, you could simply have made a unique equation at first sight that involved the changes of temperature from -45 C to 75 C, but you have a phase change in the middle. Phase change keep temperature constant but they require heat from the surroundings in order to, in the case of ice, break the bonds that keep the molecules tight together.

This heat required from the surroundings is the Enthalpy of phase change, in this case enthalpy of fusion.

10. Would it be possible for an earthquake at this same location to be felt where you live? Why or why not ?

Answers

Answer:

yes if big  no if weak

Explanation:

According to new research, a large earthquake can not only cause other quakes, but also large ones on the opposite side of the Earth.

What is an earthquake and how it is caused?

An earthquake is a sudden movement of rock materials beneath the earth's surface that causes a weak to violent shaking of the ground. The earthquakes are caused by tectonic plate boundaries.

Every day, earthquakes occur all over the world, along both tectonic plate edges and interiors. Earthquakes happen along faults, which are fractures in the rock that allow the blocks to move relative to one another.

Earthquakes are typically caused by underground rock suddenly breaking and rapid movement along a fault. The seismic waves that cause the ground to shake are caused by this sudden release of energy.

A large earthquake can not only cause other quakes, but also large ones on the opposite side of the Earth, according to new research.

Thus, it is possible for an earthquake at this same location to be basically felt where you live.

The balanced equation for this process is shown below. 3H2 N2 Right arrow. 2NH3 The molar mass of NH3 is 17. 03 g/mol. The molar mass of H2 is 2. 0158 g/mol. In a particular reaction, 0. 575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures? 0. 1 0. 102 0. 10209 0. 1021.

Answers

Answer:

B

Explanation:

We are given that ammonia can be produced from hydrogen gas and nitrogen gas according to the equation:

[tex]\displaystyle 3\text{H$_2$} + \text{N$_2$} \longrightarrow 2\text{NH$_3$}[/tex]

We want to determine the mass of hydrogen gas that must have reacted if 0.575 g of NH₃ was produced.

To do so, we can convert from grams of NH₃ to moles of NH₃, moles of NH₃ to moles of H₂, and moles of H₂ to grams of H₂.

We are given that the molar masses of NH₃ and H₂ are 17.03 g/mol and 2.0158 g/mol, respectively.

From the equation, we can see that two moles of NH₃ is produced from every three moles of H₂.

With the initial value, perform dimensional analysis:

[tex]\displaystyle \begin{aligned} 0.575\text{ g NH$_3$}& \cdot \frac{1\text{ mol NH$_3$}}{17.03\text{ g NH$_3$}} \cdot\frac{3\text{ mol H$_2$}}{2\text{ mol NH$_3$}} \cdot \frac{2.0158\text{ g H$_2$}}{1\text{ mol H$_2$}} \\ \\ & = 0.102\text{ g H$_2$}\end{aligned}[/tex]

*Assuming 100% efficiency.

Our final answer should have three significant figures. (The first term has three, the second term has four (the one is exact), the third term is exact, and the fourth term has five. Hence, the product should have only three.)

In conclusion, our answer is B.

How many grams of barium chloride are produced when 1.25 x 1023 molecules of HCl reacts with barium?

Answers

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

Balanced reaction

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Moles of HCl that react

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

Reaction stoichiometry

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HCl: 2 moles Ba: 1 mole BaCl₂: 1 mole H₂: 1 mole

Mass of barium chloride produced

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.
