Describe three properties of a frozen fruit bar

Chemistry
1 answer:
kondor19780726 [428]2 years ago
8 0

Answer:

The state of matter of a frozen fruit bar is solid. One property of solids is that they have a fixed shape, because the particles are tightly compressed and cannot move about. Another property is that solids can’t be compressed, because the particles have no space to move as a result of the compression. The frozen fruit bar has no free electrons so, like most other solids, it cannot conduct electricity.

How many grams of Cl are in 465g of CaCl2
Rama09 [41]
2 ways to do this
a. find %Cl in CaCl2
2 x 35.45g/mole = 70.9g Cl
70.9g Cl / 110.9g/mole CaCl2 = 63.93% Cl in CaCl2
0.6963 x 145g = 92.7g = mass Cl

b. determine moles CaCl2 present then mass Cl
145g / 110.9g/mole = 1.31moles CaCl2 present
2moles Cl / 1mole CaCl2 x 1.31moles = 2.62moles Cl
2.62moles Cl x 35.45g/mole = 92.7g Cl

Describe two physical and two chemical changes involved in cooking. (4 points)
Ivenika [448]
Physical changes are when things get changed without altering chemical consistencies, which is melting solid butter into liquid one, or boiling water. Chemical changes are things such as caramelizing sugar when making sweets, or when carbon dioxide is created and released when baking bread.

Please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2?
lara31 [8.8K]

Answer:

20N

Explanation:

Given parameters:

        Force(N)     Acceleration(m/s²)  

            10                   0.2

           ?                      0.4

Unknown:

The force applied when the acceleration is 0.4m/s²

Solution:

From newton's second law of motion;

 Force = mass x acceleration

 Since we are using the same box, let us find the mass of the box;

      Force  = mass x acceleration

         10 = mass x 0.2

            mass = \frac{10}{0.2}  = 50kg

Now,

 The force in the second instance will be;

      Force  = 50 x 0.4  = 20N

oksano4ka [1.4K]

Answer:

Calculating Atomic Mass

Change each percent abundance into decimal form by dividing by 100. Multiply this value by the atomic mass of that isotope. Add together for each isotope to get the average atomic mass.

Which waves can travel through empty space?
bagirrra123 [75]

Answer:

light waves a

Explanation:

because there's all kinds of different light in space if you think about it like the bright stars or the bright moon it's kind of like light it just makes sense when it's traveling for space water waves obviously it's not possible that travels through the air or like on a beach sound waves you can't really cure much in space and mechanical waves is pretty much the action of an object or something like that kind of it's pretty much happens on Earth but light waves happen for like asteroids or shooting stars a comments it happens all the time for space so it makes just perfect sense
