Answer:

RESHAPE BY A FORCE.

Explanation:

1. It can be reshaped by a force. Physical property can be observed and measured without any changes in molecular composition.

2. A physical property is one that can be change without altering the identity of the substance. These set of properties is not concentration dependent they are use to describe matter. Example are: density, solubility, melting point and color and odor. For this case the second option seems to fit the description it can be reshape by force.

A sealed glass jar has a small amount of water on the bottom. The rest of the volume in the jar is taken up by helium gas at a p

Natalija [7]

<u>Answer:</u>

The temperature of the water is 70°C

<u>Explanation:</u>

Partial pressure of helium gas = 526 mmHg

Total pressure inside the jar= 760 mmHg

Suppose partial pressure of helium gas is $P_H_e$ and partial pressure of water is $P_H__2O$

And total pressure is $P_T$

As we know

$\mathrm{P}_{\mathrm{T}}=\mathrm{P}_{\mathrm{HE}}+\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}$

Hence

Putting the values

$760=526+\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}$

$\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}=760-526$

$\mathrm{P}_{\mathrm{H} 20}=234 \mathrm{mm} \mathrm{Hg}$

In bar,

$\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}=234 \mathrm{mm} \mathrm{Hg} \times \frac{1.01325 \mathrm{bar}}{760 \mathrm{mm} \mathrm{Hg}}$

= 0.312 bar

Now according to the steam table

With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C

What is the net ion equation and spectator ions for the reaction of (aq) NaC2H3O2 and aq (NH4)2 CO3?

mestny [16]

The reaction is:

(C₂H₃O₂)²⁻ + NH₄⁺ = (NH₄)(C₂H₃O₂).

$Na^+$ and $CO_3^2 -$ are the spectator ions.

<h3><u>Explanation:</u></h3>

The reactants in the reaction is sodium acetate and ammonium carbonate. They form the soluble molecule sodium carbonate and slightly soluble ammonium acetate. This is a double displacement reaction.

Spectator ions in the reaction are those ions which are present in the reaction but they actually don't take part in the reaction that's happening and they remain same before and after the reaction. In this reaction, the spectator ions are sodium and carbonate which remain in ionized form in the solution before and after the reaction.
