Explanation:
The most common reaction of epoxide rings is the ring opening reaction. This ring opening reaction serves to relieve the stress in the ring.
Now, The first step in the acid catalysed epoxide ring opening reaction is the protonation of the epoxide.
This is now followed by the attack of the nucleophile. Subsequent deprotonation regenerates the acid catalyst and yields the product.
The structure of the product formed in the reaction of an epoxide with ethoxide ion is attached below as we get 2 substituted alcohol product.
What are epoxides?Epoxides are comes under the category of ether, which are the three membered ring structure.
Due to its ring structure, strain or stress is present in the three membered ring which makes it available to react easily with nucleophile. Ethoxide ion acts as a nucleophile in this reaction which attacks on the electrophilic carbon of the epoxide and resulting into the break up of bond and opening of ring.
As a result of this reaction we get the 2 substituted alcohol as attached in the image.
Hence structure of the product is attached below.

1) How many moles of water does 6.02 x 1023 molecules
represent?
Answers
Answer:
1.00 mol
Explanation:
Step 1: Given data
Molecules of water: 6.02 × 10²³ molecules
Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water
In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)
6.00 moles of sodium perchlorate contains the same number of atoms as __________. 6.00 moles of sodium perchlorate contains the same number of atoms as __________. 6.00 moles of sodium permanganate 6.00 moles of strontium oxide 6.00 moles of sodium cyanide 6.00 moles of lithium phosphate 6.00 moles of sodium nitrite
Answers
Answer:
6.00 moles of sodium permanganate
Explanation:
Let us attempt to count the number of atoms present in sodium perchlorate. The formula of the compound is NaClO4
Sodium atoms - 1
Chlorine atoms - 1
Oxygen atoms -4
Total number of atoms = 6
Among the options, only KMnO4 also has six atoms. One atom of potassium, one atom of manganese and four atoms of oxygen.
6.00 moles of sodium perchlorate contains the same number of atoms as: A. 6.00 moles of sodium permanganate.
How to calculate the number of atoms.First of all, we would determine the chemical formula and the number of atoms contained in each chemical compound as follows:
For sodium perchlorate:
Sodium perchlorate = [tex]NaClO_4[/tex]
[tex]NaClO_4[/tex] = [tex]1+1+2[/tex] = 6 atoms.
For sodium permanganate:
Sodium permanganate = [tex]KMnO_4[/tex]
[tex]KMnO_4[/tex] = [tex]1+1+2[/tex] = 6 atoms.
For strontium oxide:
Strontium oxide = [tex]SrO[/tex]
[tex]SrO[/tex] = [tex]1+1[/tex] = 2 atoms.
In conclusion, we can deduce that 6.00 moles of sodium perchlorate contains the same number of atoms as 6.00 moles of sodium permanganate.

pH = 7.14.
Explanation:
Hello there!
In this case, since the pH of a solution is computed via the negative logarithm of the concentration of hydrogen ions:
[tex]pH=-log([H_3O^+])[/tex]
Therefore, we plug in the given concentration to obtain:
[tex]pH=-log(7.2x10^{-8})\\\\pH=7.14[/tex]

1.29×10²⁴ atoms are in 2.15 moles of water. Atom is also the smallest piece of substance with chemical element-like characteristics.
What is atom?The smallest unit of matter that may be divided without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. As a result, the atom serves as the fundamental unit of chemistry.
Space makes up the majority of an atom. The rest is made up of a cloud of electrons that are negatively charged surrounding a nucleus that is positively charged made up of protons and neutrons. The behaviour of the electron in an atom can be compared to that of particles surrounding the nucleus.
number of atoms = number of moles ×6.022×10²³
= 2.15×6.022×10²³
= 1.29×10²⁴
Therefore, 1.29×10²⁴ atoms are in 2.15 moles of water.

Can someone help me over here? I need an negative charge and also another thing is that in a question it asked me to use something that would represent an ion. I’m not sure on what to choose either Hydrogen or Helium but just please send help.
Answers
Answer:
You could use a hydrogen anion which has 2 electrons.
Explanation:
An ion is an atom or molecule with a net electric charge because it has more or less electrons compared to the original atom or molecule.
An anion is a negatively charged ion.
A cation is a positively charged ion.
Normally a hydrogen atom has one proton and one electron.
So a hydrogen anion (H-) means that it has one proton and two electrons, which means the positive charge will be +1 and the negative charge will be -2.
Ultimately, giving the entire molecule a net charge of -1 because -2+1 = -1.
(I hope this helps! I am not 100% sure what's the format of this question. Like is it interactive? online? Did you draw all those electrons on the diagram? or were they given? Are the numbers given as well? or did you type those in? So I just tried my best to give you something that might work.)
Styrofoam has a density of 0.075 g/mL. What is the volume of 21.80 g of Styrofoam?
Answers
The answer is 290.66 mL
Explanation:
The density of any substance including styrofoam is determined by two main factors: mass (atoms in the substance) and volume (space occupied). Moreover, the volume or mass of the substance can be calculated by using the density as these variables are related. Below I show the process:
density = mass / volume
mass = density x volume
volume = mass / density
volume = 21.80 g / 0.075 g/mL
volume = 290.66 mL

What is the mass in mg of 9.3 x 1016 lead atoms? Give answer with correct
significant figures and units.
Answers
Answer:
the answer would be 9,448.8
The mass of 9.3 × 10¹⁶ lead atoms is equal to 0.032 mg.
What is Avogadro's number?Avogadro’s number represents the number of entities in one mole of any substance. Generally, these units can be molecules, atoms, ions, electrons, or protons, depending upon the type of chemical reaction or reactant and product.
The value of Avogadro’s constant is approximately equal to 6.022 × 10²³ mol⁻¹.
Given, the number of atoms of the lead = 9.3 × 10¹⁶
The atomic mass of the lead = 207.2 g/mol
So 6.022 × 10²³ atoms of lead have mass = 207.2g
Then 9.3 × 10¹⁶ lead atoms will have mass [tex]=\frac{207.2\times 9.3\times 10^{23}}{ 6.022\times 10^{23}}[/tex] = 31.998 ×10⁻⁷g
As we know, 1 gram = 1000 mg
The mass of the 9.3 × 10¹⁶ lead atoms = 31.998 ×10⁻⁴ mg = 0.0032 mg
Therefore, the mass of 9.3 × 10¹⁶ lead atoms is 0.032 mg.
