Why isn't this structure possible for an isomer of butanoic acid? Like why does the acid group always be on the end of a molecule?

Answer:

A. Things are measured the same way each time.

Explanation:

Answer:

It goes through a process called absorption. This is when an atom absorbs the energy from its surroundings. The electrons move from the ground state to the excited state because of this process. Once the atoms absorb energy, that affects the inner development when shifting to a new state of being.

Explanation:

The process that is known as absorption is when an atom absorbs energy from its surrounding racing it's energy level causing it to go into an excited state or highly-reactive state. When an atom goes through this process, electrons absorb the energy and raise to higher energy levels, therefore raising the stage of itself. This is how it gets into a excited state.

Answer:

Option 2 is correct.

Answer:

The element that is commonly used to reduce iron oxide would be carbon.

Explanation:

:)

Iron oxide is reduced to a lower oxide or metal by gaseous carbon monoxide or solid carbon.

Reduction is defined as the chemical reaction which involves addition of hydrogen or removal of oxygen or gain of electrons.

For example,

2Na + H2 → 2NaH (addition of hydrogen)

CuO + H2 → Cu + H2O(removal of oxygen)

Fe3+ + e- → Fe2+ (gain of electron)

Above example of reduction reaction is when oxygen reacts with iron to form rust. In this reaction oxygen is reduced because it accepts electrons from iron, which is oxidized.

Thus, Iron oxide is reduced to a lower oxide or metal by gaseous carbon monoxide or solid carbon.

Answer:

Three principal theories about acid-base are,

1. Arrhenius theory

2. Bronsted-Lowry theory

3. Lux-Flood definition

4. Lewis theory

5. Usanovich definition

1. According to the Arrhenius, acids give up hydrogen ion in aqueous medium and a base give up hydroxyl ion in its aqueous medium. Examples are aqueous solution of HCl, CH3COOH, PhCOOH, and H2SO4. These give up H+ in an aqueous medium. Aqueous solutions of NaOH, Ca (OH)2 are Arrhenius bases.

Arrhenius theory has some limitations. This theory cannot explain the acidic nature of BF3 or basic behavior of NH3. This theory fails to give any explanation about acidity and basicity which does not produce H+ and OH- in their aqueous solutions.

2. According to the Bronsted-Lowry, an acid releases proton and a base accepts proton. NH3 accepts proton and forms ammonium ion, so ammonia acts as a base.

But this theory also has limitations. According to this theory acidic behavior of BF3 still cannot be explained.

3. Lux-Flood describes the acid-base theories based on oxide ion transformation. It gives clear explanation for acid-bases theories of non-protonic system. According to them, a base will donate the oxygen atom and an acid will accept oxygen atom.

4. According to the Lewis theory, acids are those substances which accept electron pair and base are those substances which donates electron pairs. Lewis theory can explain the acidic nature of BF3. In BF3, B is two electrons short to fulfil its octet. So it can accept a pair of electrons from an electron donating substituent. So it is an electron pair acceptor compound and acts as an acid.

Substances which have π electrons can donate electron pair to an electron deficient substance and acts as a base. Ethylene and acetylene is Lewis bases. AlCl3, PCl3 are Lewis acids.

5. According Usanovich, an acid is some chemical species which would react with bases and yields cations or accepts anions or electrons. A base is some chemical species which would react with acids, yield anions or electrons or combine with cations.

If a mixture of hydrochloric acid and lithium hydroxide produces lithium chloride and water, 3.25 moles of water are produced from 3.25 moles of hydrochloric acid.

According to this question, a mixture of hydrochloric acid and lithium hydroxide produces lithium chloride and water. The balanced chemical equation is as follows:

HCl + LiOH = LiCl + H2O

Based on the above equation, 1 mole of HCl produces 1 mole of water.

3.25 moles of HCl will produce 3.25 moles of H2O.

Therefore, a mixture of hydrochloric acid and lithium hydroxide produces lithium chloride and water, 3.25 moles of water are produced from 3.25 moles of hydrochloric acid.

The resulting pressure of the gas after decreasing the initial volume from 2 L to 1 L is 3 atm.

According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of that gas.

For the given question we use the below equation is:

P₁V₁ = P₂V₂, where

P₁ = initial pressure of gas = 1.5 atm

V₁ = initial volume of gas = 2 L

P₂ = final pressure of gas = ?

V₂ = final volume of gas = 1 L

On putting all these values on the above equation, we get

P₂ = (1.5atm)(2L) / (1L) = 3 atm

Answer:

- Deep red fire is about 600-800° Celsius

- Answer: {1102.91}

Given: K= °C + 273.15

K = 1,376.06

Since you’re trying to find C (Celsius) you want to get C by itself in the problem. So you subtract 273.15 from that side. Anything you do to one side of the equal sign you have to do to the other side, so also subtract 273.15 from K (1,376.06).

1,376.06 - 273.15 = {1102.91°C}
