Answer:

Ethyl methyl ether.

Explanation:

  • The mono ether is named commonly by <em>dividing the molecule into two parts, writing them in alphabetical order, and adding ether in the end of the name.</em>
  • In this compound; we have two parts CH₃ (methyl) and CH₃CH₂ (ethyl).

So, it is named ethyl methyl ether.

  • The IUPAC name of this name is Methoxyethane.

What would be the products for the reaction Br2 + KI →? (Just identify the correct products for the reaction. You do not need to
Savatey [412]

<u>Answer:</u> The products of the reaction will be I_2\text{ and }KBr

<u>Explanation:</u>

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The general chemical equation for the single displacement reaction follows:

A+BC\rightarrow AC+B

The given chemical equation follows:

Br_2+2KI\rightarrow I_2+2KBr

Bromine element is more reactive than iodine element. Thus, can easily replace iodine from its chemical reaction.

Hence, the products of the reaction will be I_2\text{ and }KBr

Calculate the oxidation state of the underlined elements of K2 Cr2 O7
Semenov [28]

Answer:

+4

Explanation:

In PbO2, oxygen exhibits an oxidation number of -2 (since it's not a peroxide or superoxide):

Let the oxidation number of Pb be x. Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero.

⇒ x + (−2) + (−2) = 0

x = +4

So the oxidation no. of Pb is +4.

I hope this helps.

28 Which compound yields H + ions as the only positive ions in an aqueous solution?
MrMuchimi

Answer: (4) CH_3COOH

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydronium ions (H_3O^+) in water.

1. KOH is a strong electrolyte and thus dissociate in water.KOH\rightarrow K^++OH^-

2. CH_3OH is a non electrolyte and thus do no dissociate in water.

CH_3COOH\rightarrow no reaction

3. NaOH is a strong electrolyte and thus dissociate in water.

NaOH\rightarrow Na^++OH^-

4. CH_3COOH is a weak electrolyte and thus partially dissociate in water.

CH_3COOH\rightleftharpoons CH_3COO^-+H^+

What mass of each solute is present in 294 g of a solution that contains 4.86% by mass NaCl and 7.54% by mass Na2CO3
Angelina_Jolie [31]
In order to compute the mass of each solute in the sample, we simply multiply the percentage mass of each solute with the total mass of the solution. This is ad such:
Mass (NaCl) = 0.0486 x 294
Mass (NaCl) = 14.29 grams

Mass(Na₂CO₃) = 0.0754 x 294
Mass(Na₂CO₃) = 22.17 grams
