erik [133]

Answer:

0.35 weight fraction is liquid Forsterite and 0.65 weight fraction is liquid Fayolite

Explanation:

The lever rule is typically used to calculate the weight fractions of phases in a binary equilibrium phase diagram. It is also used in the estimation of the fraction of solid and liquid phases for a specific binary composition and temperature condition existing between the solid and liquid lines. Therefore, using the Figure. 8.9 and the use of lever rule, the composition of the remaining liquid would be 0.35 weight fraction of liquid Forsterite and 0.65 weight fraction of liquid Fayolite.

When placed in a 200-mL square box, a substance has a spherical shape and has a volume of 75 mL. When placed in a 200-mL circula
Anastasy [175]

Answer:

a. Solid

Explanation:

<em>Solid substances do not change size or shape according to their containers</em>. In other words, solid substances keep their size and shape.

<em>Liquid and gas substances take the shape of their container</em>, so any of them would be square-shaped when put in a square box, and they would be spherical shaped when put in a spherical container.
