Which term best describes the molecule shown below?

Answer:

One orientation

Explanation:

A s orbital is a sphere like shape that surrounds the atomic nucleus that consists of electrons that can be found at the highest or lowest region of the orbital. S orbitals only consist of "one orientation" and is commonly mistaken by the p orbital because the p orbital also consists of electrons that can be found the most.

A good look at the attached colour wheel reveals that blue Cu2+ ions absorbs light around the red and orange portions of the visible spectrum.

Answer: Provide the nuclear power plant with a plan to properly dispose of and recycle the wastes.

Explanation:

The nuclear power plant is producing huge amounts of electricity which is beneficial to the economy as it pushes growth. Shutting it down or relocating it is therefore not the right solution.

The problem is the radioactive waste being produced so a solution that is specific to this problem should suffice. That solution would be the provision of the nuclear plant with plans to properly dispose of the waste.

Should this happen, the nuclear plant can still stay in the same area and keep contributing to economic growth without adversely affecting people's heath.

Answer:

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.

Explanation:

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. ... These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements

Answer:

Mass of solute = 0.0036 g

Explanation:

Given data:

Concentration of Cl⁻ = 15.0 ppm

Volume of water = 240 mL

Mass of Cl⁻ present = ?

Solution:

1 mL = 1 g

240 mL = 240 g

Formula:

ppm = mass of solute / mass of sample ×1,000,000

by putting values,

15.0 ppm = (mass of solute / 240 g) ×1,000,000

Mass of solute = 15.0 ppm ×  240 g / 1,000,000

Mass of solute = 0.0036 g

Answer:

1. The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

2. A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction.

3. Toxicity and acidity.

4. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

5. The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.

pH of the Sr(OH)₂ solution : 12.6

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

Sr (OH) ₂ solution is a base with valence 2, so we determine the pOH from the OH ion concentration - which is expressed by pOH = - log [OH -]. After that we determine the pH value from the relationship:

[H⁺] [OH⁻] = Kw=10⁻¹⁴

pH + pOH = 14

Sr(OH)₂⇒Sr²⁺+2OH⁻

From equation [Sr(OH)₂] : [OH⁻]=1 : 2, so [OH⁻]=

[tex]\tt [OH^-]=2\times 2.10^{-2}=4.10^{-2}~M[/tex]

[tex]\tt pOH=-log[OH^-]\\\\pOH=-log~4.10^{-2}\\\\pOH=2-log~4\rightarrow 1.398 \\\\pH+pOH=14\\\\pH=14-1.398\\\\pH=12.6[/tex]

pH is the measurement of the concentration of hydrogen or hydronium ion in an aqueous solution. The pH of strontium hydroxide is 12.6.

The pH is the potential of hydrogen or the negative log of its concentration.

First, calculate the pOH of strontium hydroxide by:

[tex]\begin{aligned} \rm pOH &= \rm - log [OH ^{-}]\\\\&= \rm -log [4\times10^{-2}]\\\\&= 1.398\end{aligned}[/tex]

Now, calculate pH from pOH as:

[tex]\begin{aligned}\rm pH &= 14 - \rm pOH\\\\&= 14 - 1.398\\\\&= 12.6\end{aligned}[/tex]

Therefore, 12.6 is the pH of strontium hydroxide.

Answer:

Giant covalent are characterized by having high melting and boiling points as well as being solid at room temperature. Hence, option C is correct.

A covalent bond shares one or more pairs of electrons between two atoms.

Giant covalent structure:

Polythene: long chains of atoms that are able to rotate along the bonding axis.

Graphite: layers of (hexagonal) carbon sheets; each individual sheet are rigid (allows no rotation.)

Silicon dioxide: three-dimensional (tetrahedral) network of carbon and oxygen atoms; the entire network is very rigid (allows no rotation.)

Diamond: three-dimensional (tetrahedral) network of carbon atoms and is very rigid.

Hence, giant covalent are characterized by having high melting and boiling points as well as being solid at room temperature.

Answer:

5.The limiting reactant is completely used up in the reaction

Explanation:

The limiting reactant is completely used up in the reaction is the correct answer because a limiting reactant is a reactant in chemical reaction that is completely consumed or used up in the chemical reaction. Limiting reactant when it is completely used up limits the amount of products that will be formed. The reaction will be halted or will stop when the limiting reactant is totally used up.

The statement that is right as regards a limiting reactants in a reaction is 5:.The limiting reactant is completely used up in the reaction.

Therefore, option 5, is correct.

Explanation: Hope this helps!!!

Answer:

Explanation:

The given compound is:

           KC₈H₆O₄

Mass of the compound = 25g

Molar mass of the compound

KC₈H₆O₄

   Atomic mass of K  = 39

                             C  = 12

                             H = 1

                             O = 16

Molar mass of the compound  = 39 + 8(12) + 6 (1) + 4(16)

                                                   = 205g/mol

Number of molecules of fuel there in:

Find the number of moles then convert this to number of molecules;

    Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

    Number of moles  = [tex]\frac{25}{205}[/tex]   = 0.12mol

1 mole of a compound contains 6.02 x 10²³ molecules

 0.12 mole of the phthalate will contain 0.12 x 6.02 x 10²³ =

              7.34 x 10²²molecules

Number of moles of Carbon

  1 mole of the phthalate contains 8 mole of carbon

  0.12 mole of the phthalate will contain 0.12 x  8  = 0.96mole of carbon
