The correct name of the hydrocarbon is based on the arrangement of the substituents present.

Hydrocarbons are named based on the type of structure they have. Here are the most common naming conventions:

Alkanes: Named based on the number of carbons in the chain, with the suffix "-ane".

Alkenes: Named by changing the suffix of the alkane name from "-ane" to "-ene".

Alkynes: Named by changing the suffix of the alkane name from "-ane" to "-yne".

Aromatic hydrocarbons: Named as "benzene", "toluene", "phenol", etc.

Cyclic hydrocarbons: Named based on the number of carbons in the ring, with the prefix "cyclo" and the suffix "-ane", "-ene", or "-yne".

The mechanism of  the reaction of an alkene with an electrophile attached below

There's 2 steps in reaction between alkene and electrophile

The K in the KI electrophile is attacked by the two pi electrons from the double bond during the first step of the process, which is denoted by a curved arrow. The hydrogen from HBr and a carbon from the double bond combine to produce a C-H sigma bond thanks to the two pi electrons. In order to create a halide anion, the electrons from the H-X bond simultaneously transfer to the halogen. One of the carbons becomes an intermediate carbocation with an electron deficit when pi electrons from the double bond are removed. The positive charge is housed in an unhybridized p orbital on this sp2 hybridized carbon atom.

In order to receive an electron pair from the nucleophilic halide anion, the generated carbocation can now function as an electrophile. The neutral alkyl halide is the end result of electrophilic addition, and the electron pair transforms into an X-C sigma bond.

The HBr, HCl, HI, and HF halides can all take part in this reaction and add on in the same way. Although various halides do react at varying rates, this is because the H-X bond weakens with increasing X due to inadequate orbital overlap.

Answer:

1.01×10⁻¹⁶ moles (to 3 significant figures)

Explanation:

Using avocado's constant, we can use it to find the number of moles (x) for 61,000,000 atoms of Ne:

1 mole = 6.02×10²³ atoms

x = 61,000,000 atoms

We can solve this by cross-multiplying:

6.02×10²³ × x = 1 × 61,000,000

6.02×10²³x = 61,000,000

To solve for x, divide both sides by 6.02×10²³x:

[tex] \frac{6.02×10²³x}{6.02×10²³} = \frac{61,000,000}{6.02×10²³ } [/tex]

This cancels out both 6.02×10²³ on the left

The correct Lewis structure for Group 5A element, Arsenic is structure A.

What are Lewis structure?

A very simplified representation of a molecule's valence shell electrons is known as a Lewis structure. The octet rule, which states that atoms share electrons such that each has eight in its outer shell, is the foundation of a Lewis structure. Lewis structures are used to examine and comprehend chemical bonds and atomic structures.

Arsenic is an element that, as far as we are aware, belongs to group 15 and has a total of 5 valence electrons. The structure shows the five covalent bonds that bind arsenic to one another chemically. So, once one electron is filled in isolation, pairing takes place.

Arsenic's true Lewis structure, thus, is structure A for Group 5A element.

Every time a problem provides you with a compound's molar mass, you can use a little trick to help you determine the compound's molecular mass faster.

More specifically, instead of determining the empirical formula first, then using the molar mass to get the molecular formula, you can skip the empirical formula altogether.

As you know, a compound's molar mass tells you what the mass of one mole of that substance is. In this case, one mole of your compound has a mass of 142.00 g.

This means that if you pick a sample of 142.00 g of this compound, you can use its percent composition to get the exact number of moles of each element you get per mole of compound.

So, you know that this compound's percent composition is as follows

carbon→50.7 %

hydrogen→4.2%

oxygen→45.1 %

This means that it contains

Answer:

180 m^2

Explanation:

The total area of the vegetable patch and the orchard can be found by adding 46.2m^2 and 133.6m^2, which equals 179.8m^2. Rounded to the nearest square meter, the total area is 180m^2.

To find the total area of the vegetable patch and the orchard, we simply need to add their respective areas together. From this, the total area of the vegetable patch and the orchard is approximately 179.8 square meters when rounded to the nearest square meter.

Area of the vegetable patch = 46.2 m²

Area of the orchard = 133.6 m²

Total area = Area of the vegetable patch + Area of the orchard

Total area = 46.2 m² + 133.6 m²

Total area = 179.8 m²

The acidic strength gives the pH of the neutralized reaction. When a strong acid solution reacts with a strong base the generated salt can be neither acidic nor basic, it should be neutral.

When a strong acid reacts with a weak base, the formed salt will be acidic in nature. When a strong base will react with a weak acid then the formed salt will be basic in nature and have the pH level of the solution.

Option  (b) and (d) are correct. As the strength of a Bronsted-Lowry base increases, its conjugate acid becomes weaker and the higher the pKa value of its conjugate acid.

According to the Bronsted-Lowry base, base is a proton acceptor. Once an acid has given up a proton the part that remains is called the acid's conjugate base. This species is a base because it can accept a proton to re-form the acid. The part of the base that remains after a base accepts a proton is called the base's conjugate acid. The determination of a substance as a Bronsted-Lowery acid or base can only be done by observing the reaction. In this theory, an acid is a substance that can release a proton like in the Arrhenius theory and a base is a substance that can accept a proton. A Bronsted - Lowry base  accepts proton , H+  from a Bronsted - Lowry acid. As the strength of a Bronsted - Lowry base increases then the strength of its conjugate acid decreases and Ka value of conjugate acid  decreases and pKa value of conjugate acid increases.

To determine the mass of NaCl that reacted with F2 at 290 K and 1.5 atm, we can rearrange the equation as follows: n = PV/RT. Substituting in the values for P, V, R, and T, we get: n = (1.5 atm)(18.0 L)/(0.0821 atm*L/mol*K)(290 K) = 0.835 mol NaCl.

To determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP (standard temperature and pressure), we would use the same equation but with the values for P, V, R, and T corresponding to STP. At STP, P = 0.987 atm, V = 18 L, R = 0.0821 atm*L/mol*K, and T = 273 K. Therefore, n = (0.987 atm)(18 L)/(0.0821 atm*L/mol*K)(273 K) = 0.792 mol NaCl.
