Answer:

D) N-Cl.

Explanation:

The electronegativity of the elements in Group 5 (N. P As and Bi) decreases as we go down the Group so N is the most electronegative and chlorine is less able to draw electrons away from N than from the other elements in Group 5.

The mechanical advantage of a device refers to
Savatey [412]

Answer:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

Sodium thiosulfate, Na 2S 2O 3, is used as a "fixer" in black and white photography. Identify the reducing agent in the reaction
Tatiana [17]

Answer: Reducing agent in the given reaction is S_{2}O^{2-}_{3}.

Explanation:

A reducing agent is defined as an element which tends to lose electrons to other element leading to an increase in its oxidation number.

In the given reaction, oxidation state of sulfur in S_{2}O^{2-}_{3} is +2 and I_{2}(aq) has 0 oxidation state.

In S_{4}O^{2-}_{6}(aq) oxidation state of S is 2.5 and in 2I^{-}(aq) oxidation state of I is -1.

Since, an increase in oxidation state of S is occurring from +2 to +2.5. Hence, it is acting as a reducing agent.

Thus, we can conclude that reducing agent in the given reaction is S_{2}O^{2-}_{3}.

Marianna [84]

Answer:

Carbonated drinks in cans have a headspace to avoid explosion

Explanation:

  • When we see in carbonated drinks in cans we can see there is a small amount of space above the liquid level known as the headspace. This space is not a wasted space. The gas filled in the can is compressed highly which when opened comes out with a high pressure with an explosion.
  • Therefore, to avoid the carbonated drinks not to explode when shaken the carbonated drinks and the bottled juices have headspace. This means the headspace is not wasted.
