Answer:

C) Fluorine has the strongest tendency to attract electrons.

Explanation:

Electronegativity is the tendency of the atom in a covalent bond to attract the shared pair of electron towards itself.

Down the group, size increases which means that the nucleus become far from the valence electrons and thus decreased electronegativity as there will be less tendency to attract the shared electrons.

Fluorine and iodine are in the same group and thus fluorine has higher tendency to attract electrons and thus has the highest electronegativity.

GREYUIT [131]

The answer is most likely that the answer is B. Because Space is a dangerous place in which you need certain things to explore it. If you want to go to to Jupiter, for example you need lots of Oxygen, fuel, a good rocket, willing people and many more things, but there is a way technology can skip all that. the technology we have now is not capable of doing that though.

A student prepares a solution by dissolving 60.00 g of glucose (molar mass 180.2 g mol-1) in enough distilled water to make 250.

anyanavicka [17]

Answer:

1.332 Molar is the molarity of the glucose solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

$Molarity=\frac{\text{Mass of compound}}{\text{Molar mas of compound}\times Volume (L)}$

Mass of glucose = 60.00 g

Molar mass of glucose = 180.2 g/mol

Volume of the solution = V = 250.0 mL = 0.250 L

(1 mL = 0.001 L)

$Molarity=\frac{60.00 g}{180.2 g/mol\times 0.250 L}=1.332 mol/L$

1.332 Molar is the molarity of the glucose solution.

Heating a particular ether with HBr yielded a single organic product. Which of the following conclusions can be reached?

saw5 [17]

Only C is correct.

A will produce either an methylbromide + alcohol

B will produce alcohol and alkyl bromide as well

C cyclic ether when reacted with HBr will only produce 1 product which has alcohol group (-OH group) on one end and Bromide group on the other end
