a. Anna's chemistry class is going to be experimenting with AgNO3 today, which
can stain hands and clothes. Anna is concerned about her jewelry, so as she
gets ready for school, she removes her gold (Au) ring andreplaces it with a
cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (3 points)

Answers

Answer:

No. While gold would not react with a silver nitrate solution, nickel would.

Explanation:

Refer to the metal reactivity series.

Reactivity: [tex]\text{Gold} < \text{Silver} < \text{Nickel}[/tex].

Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.

However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.

Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.

activation energy in reaction is used to:
A- Overcome repulsion force between colliding molecules
B- Breaking bonds
C- Merge Valence electrons
D- All of them ​

Answers

Answer:

D — All of them

Explanation:

The activation energy in a reaction is the minimum amount of energy required for a chemical reaction to take place. Since all the options are processes in a chemical reaction, D should be the answer.

Activation energy is Reaction is used to: Overcome repulsion force between colliding molecules, breaking bonds and Merge Valence electrons. So the obvious answer is D all of them


i. Three different representations of glucose are
given below. Identify each type
of model.

Answers

Answer:

Ball and stick model is 3D and has the atoms depicted as different Coloured balls Conected to each other by "sticks"

fischer projection has the atoms on the side coming out of the plane, the atoms at the ends going behind (going away from you)

bond line notation Is the most common it does not show the C or H bonds but instead carbons are represented by the bends

The three structures of glucose represent three different models, they are ball and stick model, Fischer projection and bond line notation, respectively.

Glucose is a type of simple sugar (carbohydrate) that does not further hydrolyze to give monosaccharides.

Ball and stick model: The atoms are portrayed as different colored balls connected to each other by "sticks." Fischer projection: The atoms on the sides of the plane are coming out of the plane, while the atoms at the ends are moving behind.Bond line notation: It is the most frequent representation method used; it lacks C and H bonds but instead depicts carbons through bends.

Therefore, the three glucose structures reflect three distinct models: the ball and stick model, the Fischer projection, and the bond line notation, respectively.

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: CaCO,CaO+CO, He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer.​

How many atoms of lead are present in 78.40 grams of lead?

Answers

mole = 78.40/207.2

1 mol = 6.02 × 10^23 atoms

0.379 mol = X

X = 0.379/1 × 6.02 × 10^23

= 6.296 × 10^-25 atoms

Solve for x if 1/2x-3 + 5x/2x+6 =2​

Answers

Answer:

by which method do you need

The value of x is "[tex]\bold{(2, \frac{21}{2})}[/tex]".

Given:

[tex]\to \frac{1}{2x-3} + \frac{5x}{2x+6} =2[/tex]

To find:

x=?

Solution:

[tex]\to \frac{1}{2x-3} + \frac{5x}{2x+6} =2 \\\\[/tex]

Taking lcm:

[tex]\to \frac{2x+6 +5x(2x-3)}{(2x-3)(2x+6)} =2\\\\\to \frac{2x+6 +10x^2- 15x}{(4x^2+ 12x-6x-18)} =2\\\\\to \frac{10x^2- 13x+6}{4x^2+ 6x-18} =2\\\\[/tex]

[tex]\to 10x^2- 13x+6 = 2(4x^2+ 6x-18)\\\\\to 10x^2- 13x+6 = 8x^2+ 12x-36\\\\\to 10x^2- 13x+6 - 8x^2- 12x +36=0\\\\\to 2x^2-25x+42=0\\\\[/tex]

compare the value with the [tex]ax^2+bx+c=0[/tex]:

[tex]\to a=2\\\\\to b= -25\\\\\to c=42\\\\[/tex]

Using formula:

[tex]\to \bold{x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}[/tex]

       [tex]\bold{=\frac{- (-25) \pm \sqrt{(-25)^2-4\times 2 \times 42}}{2 \times 2}}\\\\ \bold{=\frac{25 \pm \sqrt{ 625 - 336}}{4}}\\\\ \bold{=\frac{25 \pm \sqrt{289}}{4}}\\\\ \bold{=\frac{25 \pm 17 }{4}}\\\\ \bold{=(\frac{8}{4} , \frac{42}{4})}\\\\ \bold{=( 2 , \frac{21}{2})}\\\\[/tex]

What kind of elements form covalent compounds?

Answers

Well, covalent bonding usually occurs between non-metals.
So some examples of covalent compounds may include:

O2 – oxygen.
Cl2 – chlorine.
H2 – hydrogen

as these all occur between non metals.

Answer:

Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between elements that are far apart on the periodic table.

dubnium chloride chemical formula

Answers

Answer:

Db

Dubnium/Symbol

Explanation:

please mark my answer in brainlist plz

Answer:

DbCl5

Explanation

Dubnium has 2 electron in 7s orbital and 3 electron in 6d orbital. Because Dubnium is synthetically produced with atomic number of 105, it is highly radioactive and quickly decay. Like other transition, it can have different oxidation state and it is assumed that dubnium have +3,+4,+5 oxidation state number(that most likely involves electron from 6d orbital). Hence chloride ions with -1 oxidation number would react to form Dubnium Chloride as DbCl3, DbCl4, and DbCl5. Now it is highly unlikely these compounds can really be formed. However if you read nature chemistry article https://www.nature.com/articles/nchem.2610, there is mention that DbCl5, DbBr5, and DbOCl3 may be expected to form.

Pure silver has a brilliant white metallic luster. How many moles of silver, Ag, are in 7.54 × 1023 atoms of silver?

Answers

The number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles

From the question,

We are to determine the number of moles of silver, Ag, that are present in 7.54 × 10²³ atoms of silver

From the formula

[tex]Number\ of\ moles =\frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]

Avogadro's  constant = 6.022 × 10²³  atoms mol⁻¹

and

From the given information

Number of silver atoms = 7.54 × 10²³ atoms

Putting the parameters into the formula, we get

Number of moles of silver present = [tex]\frac{7.54\times 10^{23} }{6.022\times 10^{23}}[/tex]

Number of moles of silver present = 1.2520757 moles

Number of moles of silver present ≅ 1.25 moles

Hence, the number of moles of silver, Ag, that are in 7.54 × 10²³ atoms of silver is 1.25 moles
