Answer: +2

Explanation:

It would be positive/plus 2 because electrons are negative. Think of it this way, if you subtract a negative, the answer is would be positive. (Ex: 3-2=1 because you are taking away 1 but if it were 3-(-2) it would be positive 5 bc it 2 negatives cancel each other and make a positive answer)

What is the final volume of a 400 ML sample that is subjected To a temperature change from 22 Celsius to 30 Celsius in a pressur
bija089 [108]

Answer:

The answer to your question is  V2 = 867.3 mL

Explanation:

Data

Volume 1 = V1 = 400 ml

Temperature 1 = T1 = 22°C

Pressure 1 = P1 = 760 mmHg

Volume 2 = V2 = ?

Temperature 2 = T2 = 30°C

Pressure 2 = P2 = 360 mmHg

Process

1.- Convert Celsius to Kelvin

T1 = 22 + 273 = 295°K

T2 = 30 + 273 = 303°K

2.- Use the Combined gas law

              P1V1/T1 = P2V2/T2

- Solve for V2

            V2 = P1V1T2 / T1P2

- Substitution

            V2 = (760 x 400 x 303) / (295 x 360)

- Simplification

            V2 = 92112000 / 106200

-Result

            V2 = 867.3 mL

Treatment of ethyl acetoacetate with NaOEt (2 equiv) and BrCH2CH2Br forms compound X. This reaction is the first step in the syn
valkas [14]

Answer:

See explanation below

Explanation:

In this reaction we have the ethyl acetoacetate which is reacting with 2 eq of sodium etoxide. The sodium etoxide is a base and it usually behaves as a nucleophyle of many reactions. Therefore, it will atract all the acidics protons in a molecule.

In the case of the ethyl acetoacetate, the protons that are in the methylene group (CH3 - CO - CH2 - COOCH2CH3) are the more acidic protons, therefore the etoxide will substract these protons instead of the protons of the methyl groups. This is because those hydrogens (in the methylene group) are between two carbonile groups, which make them more available and acidic for any reaction. As we have 2 equivalents of etoxide, means that it will substract both of the hydrogen atoms there, and then, reacts with the Br - CH2CH2 - Br and form a product of an aldolic condensation.

The mechanism of this reaction to reach X is shown in the attached picture.

Answer:

Corresponds to a covalent compound.

Explanation:

Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.

It is synthesized by the reaction between hydrogen fluoride and boron oxide:

B2O3 + 6 HF → 2 BF3 + 3 H2O
