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.

Virty [35]

Answer: 0.0009 moles of octane were used up.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

Given mass of octane = 0.1 g

Molar mass of octane = 11.23 g/mol

Putting in the values we get:

$\text{Moles of octane}=\frac{0.1g}{114.23g/mol}=0.0009moles$

Thus 0.0009 moles of octane were used up.

What is Dalton's law of partial pressure

Leto [7]

If 3 substances be x,y,z

$\\ \tt\longmapsto P_{net}=P_x+P_y+P_z$

Where

$\\ \tt\longmapsto P_x=\dfrac{n_xRT}{V}$

$\\ \tt\longmapsto P_y=\dfrac{n_yRT}{V}$

$\\ \tt\longmapsto P_z=\dfrac{n_zRT}{V}$

P is partial pressure
n is number of moles
V is volume
T is temperature
