Volgvan2 years ago
4 0

Answer:

308.7 mL

Explanation:

V1/T1 =V2/T2           T must be in K units

V2 = V1T2/T1

     =  (.250)(95 + 273.15) / (25 + 273.15)  = .3087 LITER

If a student has 125 mL of a 4.00 M CuSO4 solution and needs a 1.50 M solution, what volume do they need to dilute it to?
lara31 [8.8K]

Answer:

333.3mL

Explanation:

Using the formula as follows:

C1V1 = C2V2

Where;

C1 = initial concentration (M)

C2 = final concentration (M)

V1 = initial volume (mL)

V2 = final volume (mL)

According to the information provided in this question,

C1 = 4.00M

C2 = 1.50M

V1 = 125mL

V2 = ?

Using C1V1 = C2V2

4 × 125 = 1.5 × V2

500 = 1.5V2

V2 = 500/1.5

V2 = 333.3mL

Therefore, the CuSO4 solution needs to be diluted to 333.3mL to make 1.50 M solution.

Question : The above compound is an ether. Give thestructure
Sphinxa [80]

Answer:

The above compound is an ether. Give thestructure  of the product(s) and indicate the major mechanism of the reaction  (SN1, SN2, E1 or E2). Indicate stereochemistry when necessary.

The mechanism that explains this transformation begins with the protonation of the  ether, which allows the subsequent SN2 attack of the iodide ion. This reaction forms  ethyl iodide and ethanol, which is also converted to ethyl iodide by reaction  with excess HI.

Explanation:

The SN2 reaction (also known as bimolecular nucleophilic substitution or as an attack from the front) is a type of nucleophilic substitution, where a pair of free electrons from a nucleophile attacks an electrophilic center and binds to it, expelling another group called the leaving group. Consequently, the incoming group replaces the outgoing group in one stage. Since the two reactant species are involved in this slow limiting stage of the chemical reaction, this leads to the name bimolecular nucleophilic substitution, or SN2. Among inorganic chemicals, the SN2 reaction is often known as the exchange mechanism.

Calculate the molar concentration of the Cl⁻ ions in 0.098 M MgCl2(aq).
SVETLANKA909090 [29]
MgCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MgCl2 that dissolves.
MgCl2(s) --> Mg+(aq) + 2 Cl⁻(aq)
            [Cl⁻] = 0.098 mol MgCl2/1L × 2 mol Cl⁻ / 1 mol MgCl2 = 0.20 M
The answer to this question is [Cl⁻] = 0.20 M
