Answers

Answer 1

They prefer the path of least resistance due to flux density. With a magnet, the lines of force are peacefully lying with the iron nail

What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?

Answers

Answer:

Electric Current

Explanation:

The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit.  Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.

Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.

Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.

The yellow arrow in the diagram shows the flow of electrons.

Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.

Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.

How many moles of O2 will be produced from 2.25 moles of KCIO3?

Answers

Answer:

3.375moles of O₂

Explanation:

The reaction expression is given as;

                   2KClO₃ → 2KCl + 3O₂

Number of moles of KClO₃  = 2.25moles

Now;

To find the number of moles of O₂ produced we use known number of moles.

So;

                  2 mole of KClO₃ will produce 3 moles of O₂

                 2.25moles of KClO₃ will produce [tex]\frac{2.25 x 3}{2}[/tex]   = 3.375moles of O₂

You have a shiny metal disc that weighs 1.31 kg that you want to find out what its made of. When you put the disc into a graduated cylinder with 5L in it, you see that the water level rose by about 125 mL. You have a list of densities for various shiny metals: silver= 10.5 g/ mL, nickel= 8.9 g/mL, titanium = 4.5 g/mL, and rhodium = 10.7 g/ mL. What is the disc made of?

Answers

Answer:

The disc is made of silver.

Explanation:

To solve this question we need to calculate the metal's density. To do so we need its mass (already given by the problem, 1.31 kg) and its volume.

Following Archimedes' principle, the volume of water displaced by the disk is equal to the disk's volume. This means the metal's volume is 125 mL.

Now we convert 1.31 kg into g, to better compare with the given options:

1.31 kg * 1000 = 1310 g

Finally we calculate the metal's density:

Density = Mass / VolumeDensity = 1310 g / 125 mL = 10.48 g/mL

Looking at the densities given by the problem, the closest one is silver.

The identity of the element shown in the model above is determined by the number of -

Answers

Answer:

The number of protons or electrons in its atomic structure

Explanation:

Elements are substances which constitute the building block of matter. The smallest particles of elements that can ever exist are known as atoms. Atoms of different elements are different in their structure properties. This difference is due to to the number of sub-atomic particles present in the atom of each element.

The three sub-atomicparticles are protons, neutrons and electrons. Protons and neutrons are present in the nucleus of an atom, while the electrons revolve around the nucleus in orbits. The identity of each element is determined by the number of protons present in the atomic nucleus of that element. This is known as the atomic number of that element. For neutral atoms, the proton number is equal to electron number.

For the given element, the electron and proton number are respectively 4, therefore, the atomic number of the element is 4. The element with atomic number 4 is Beryllium.

Criminalist Julie Sandel is investigating a series of threatening notes written in pencil and sent to a local politician. A suspect is arrested and Julie directs the suspect to prepare writing samples to compare to the writing on the notes. She has the suspect sit at a desk in an empty office and gives him a pen and a piece of paper. She begins to read one of the notes and asks the suspect to write the words she dictates. After reading about half a page, she stops, then dictates the same part of the note a second time for the suspect. At one point, the suspect indicates that he does not know how to spell one of the words, so Julie spells it for him. After completing the task, Julie takes the origi- nal notes and the dictated writing from the suspect to a document examiner. What mistakes, if any, did Julie make?

Answers

Answer:

See explanation

Explanation:

Julie Sandel, the Criminalist  made several mistakes in handling this investigation. They include;

It is true that handwriting can be deduced by comparing a suspects's handwriting to the questioned document, however Julie made a mistake by not making the suspect to write many pages. The suspect may intentionally decide to change his/her hand writing. This trick can be neutralized by asking the suspect to write several pages.

Secondly, the suspect ought to have been given a pencil and paper similar to the one used to write the threatening document. Rather, Julie gave the suspect a pen.

Thirdly, the suspect only wrote half a page instead of a full page. Secondly, Julie took only two exemplars when she should have taken more.

She should not have dictated the spelling of any word to the suspect. The examiner is not supposed to do that.

The threatening documents should have first been shown to the document examiner before taking the exemplars.

A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the given Lewis structure and what you know about VSEPR theory, identify the shape of the molecule. A molecule with atom Y single bonded with 2 X substituents. The Y atom has two lone pairs.

Answers

Answer:

Orbital geometry is Tetrahedral

Molecular geometry is Bent/V shape

Explanation:

Using the VSEPR theory which states that

The shape of a molecule depends upon the number of valence shell electron pairs  (bonded or nonbonded) around the central atom. Pairs of electrons in the valence shell repel  one another since their electron clouds are negatively charged. These pairs of electrons tend to occupy such positions in space that minimize  repulsion and thus maximize distance between them. The valence shell is taken as a sphere with  the electron pairs localizing on the  spherical surface at maximum distance  from one another. A multiple bond is treated as if it is a single  electron pair and the two or three electron  pairs of a multiple bond are treated as a single super pair. Where two or more resonance structures  can represent a molecule, the VSEPR  model is applicable to any such structure

so we have Y as the central atom and it has 2X substituents on its either sides with two lone pairs on Y. This is a case of Y which has

2 bonds with X on either sides

2 lone pairs on Y

The orbital geometry will be Tetrahedral but its Molecular geometry will be Bent/V shaped

The formula of the compound will be YX2

Water with chemical Formula of H2O bears the same features.

The shape of the given molecule according to the VSEPR theory has been Bent/V shape.

VSEPR theory has been the Valence Shell Electron Pair Repulsion theory. It helps in the determination of the molecular and geometrical shape based on the presence of the atoms attached.

The given molecule has the presence of 2 single-bonded X atoms.

The atoms repel each other, while the presence of loan pairs results in the force for the molecule to occupy the tetrahedral orbital geometry. The repulsion from the loan pair to the X atoms acquires the Bent V shape as molecular geometry.
