D.
This happens because in warmer temperatures, the atoms are more active. This increases the pressure because each atom uses up more space as they become more active.

Which of the following types of equations will include spectator ions

krek1111 [17]

Answer:- B) Full ionic equation

Explanations:- A molecular equation does not have ions. It is the non charge form of the elements of compounds. When we write the full or total ionic equation for the molecular equation then ions are written for the aqueous species. The ions present on both sides(reactant and product sides) in a full ionic equation are known as spectator ions or common ions. These ions are canceled to get the net ionic equation. For example, reaction of aqueous solution of silver nitrate with aqueous solution of barium chloride to form aqueous solution of barium nitrate and a precipitate of silver chloride.

Balanced molecular equation:-

$BaCl_2(aq)+2AgNO_3(aq)\rightarrow Ba(NO_3)_2(aq)+2AgCl(s)$

Full ionic equation:-

$Ba^+^2(aq)+2Cl^-(aq)+2Ag^+(aq)+2NO_3^-(aq)\rightarrow Ba^+^2(aq)+2NO_3^-(aq)+2AgCl(s)$

If we look at the above full ionic equation then barium ion and nitrate ions are the spectator ions are they are present on both sides.

So, while writing the net ionic equation, these spectator ions are canceled.

Net ionic equation:-

$2Cl^-(aq)+2Ag^+(aq)\rightarrow2AgCl(s)$

So, it is also clear from the above example that it's the full ionic equation that include spectator ions.

The acceleration due to gravity of all objects in free fall is the same. Why, then, do some objects fall through the air at a di

kenny6666 [7]

Answer:

Displacement. (I think)

Explanation:

When you observe both a bowling ball and a feather falling to the ground at the same time, you see that the feather falls much slower. This is because the feather displaces the air around it.

Look closer at the feather. Notice that all the feather is are fibers sprouting from the quill. The air moves through these fibers slower and displaces the air around them. this is what helps birds to fly and glide.

Now observe someone in a flight suit. A flight suit has a type of fabric webbing in-between the arms and legs of the wearer. This allows them to glide through the air (when they gain lift) because the higher surface area of a light material displaces the air around it.

Regards! (And sorry if I'm wrong!)
