Answer:

Answer B

Explanation:

By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.

A concentration cell consists of two sn/sn2+ half-cells. the electrolyte in compartment a is 0.24 m sn(no3)2. the electrolyte in
Vikentia [17]
A:-      sn(s) =>  Sn +2(0.24 M) + 2e-
B:-     Sn +2 (0.87 M) +2e-  =>   Sn(s) 

solution will become more concentrated and solution B become less concentrated 

Sn(s)+ Sn +2(0.87 ) ----> Sn(s) + Sn  +2(0.24)
E  =   Eo  -   0.0592 / 2 * log   [   (0.24 / 0.87 ) ]
E  = 0.0   -   0.0592 / 2   *   log ( 0.275) 
( n=2 two electrons are transferred)

E =  -0.0296 *  ( - 0.560) 
E =  0.0165 volts

Which type of bond is present in hydrogen sulfide (H2S)? The table of electronegativities is given
LuckyWell [14K]

Bonds formed between atoms can be classified as ionic and covalent

Ionic bonds are formed between atoms that have a high difference in the electronegativity values.

In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds.  If the atoms have very similar electronegativities, they form non-polar covalent bonds.

In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).

A sample of an ideal gas has a volume of 0.500 L at 25 degrees celcius and 1.20 atm pressure. What is its volume at 75 degrees c
NemiM [27]
The ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K

Which of these is a reason an engineer may choose to use a prefabricated
Maksim231197 [3]

Answer:

B.

Explanation:

customization requires more material, more machine time which can creates a greater impact on the environment in the sense of pollution (travel by the extra employees, creation of custom materials, increased machine running time). Good luck in your studies. Hope this answers your question in full.
