Question

Ice cubes are placed inside a glass of water on a hot day. Before the ice cubes melt, is this an example of a heterogeneous or a homogeneous mixture? Briefly explain.

Answer #1

A **homogeneous mixture** is a mixture where the
components that make up the mixture are uniformly distributed
throughout the mixture. The composition of the mixture is the same
throughout.

There is only one phase of matter observed in a homogeneous mixture.

A **heterogeneous mixture** is a mixture where the
components of the mixture are not uniform or have localized regions
with different properties. Different samples from the mixture are
not identical to each other.

There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (.e.g., liquid, solid).

So, Before the ice cubes melt, as it is a mixture of 2 phases , it is a heterogeneous mixture. After ice cubes melt, it is a homogeneous mixture

Three 100. g ice cubes are dropped in 750. grams of water (at
70.00 C) in a Styrofoam cup.
If the ice cubes were initially at -150C, how much
energy is necessary to warm and melt the ice cubes?
Will the ice cubes
melt?
Cice = 0.53
cal/g*OC
Lf = 79.5 cal/g
What is the final temperature of the system?

The ice maker inside a refrigerator makes ice cubes at 0.0°C
from water that is at 13.2°C when it first enters the ice maker. If
this machine is rated at 224 W and has a 3.56 coefficient of
performance, what is the maximum amount of ice it can produce in a
24 hourperiod without any interruption or stoppage? Assume that the
ice maker works just like a refrigerator. The specific heat of
water is 4184 J/(kg · °C), and the...

42 * A piece of ice is placed in a container before it is filled
to the brim with water. Once the water has been poured, the top of
the piece of ice then exceeds the edge of the container. Does the
container overflow when the ice melts?
A. It depends on the amount of ice placed in the container at the
start
B. Yes, whatever time it takes for the ice to melt
C. Not enough data to answer...

cup of iced water has 50 g of ice cubes in 100 g of water all at
0 degrees celsius in a room where the air temp if 27 degrees
celsius. soemtime later all the ice cubes melt into water still at
0 degrees celsius. what is the change in entropy of A) the iced
water? what is the change in entropy for the room and the change in
entropy for the "universe"?

Two 20.0-g ice cubes at –20.0 °C are placed into 275 g of water
at 25.0 °C. Assuming no energy is transferred to or from the
surroundings, calculate the final temperature of the water after
all the ice melts.

Two 20.0-g ice cubes at –16.0 °C are placed into 295 g of water
at 25.0 °C. Assuming no energy is transferred to or from the
surroundings, calculate the final temperature of the water after
all the ice melts.

Two 20.0-g ice cubes at –15.0 °C are placed into 225 g of water
at 25.0 °C. Assuming no energy is transferred to or from the
surroundings, calculate the final temperature of the water after
all the ice melts.

surroundings, calculate the final temperature of the water after
all the ice melts.

Two 20.0-g ice cubes at –19.0 °C are placed into 275 g of water
at 25.0 °C. Assuming no energy is transferred to or from the
surroundings, calculate the final temperature of the water after
all the ice melts.
