A solid rubber ball with a mass of 5.9 grams sank in water. A hollow rubber ball with the same mass floats in water. Explain why

this might be. Please answer ASAP!
Chemistry

Stells [14]3 years ago

Answer:

The hollow ball is more buoyant than the solid ball.

Explanation:

The hollow ball will float while the solid ball sinks because the volume of water displaced by the hollow ball is more than that displaced by the solid ball.

An object floats when it displaces a volume of water equal to its weight.  A solid ball is more compact, and hence, does not displace a lot of water when dropped into a bowl full of water. On the other hand, the hollow ball will have a larger curved surface area, since it has no fill. This will make it displace a larger volume of water and hence make it float.

What is the density of a 6 g of pure copper with a volume of 12 mL?
Sati [7]

Answer:

The density of copper is 0.5 g/mL

Explanation:

Given data:

Mass of copper = 6 g

Volume of copper = 12 mL

Density of copper = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

d = 6 g/ 12 mL

d = 0.5 g/mL

Thus, the density of copper is 0.5 g/mL

How is a polymer like a chain of paper clips
velikii [3]
A polymer is a really long chain of smaller molecules (monomers). It's similar to a chain of paper clips because all of the little monomers will attach to each other, forming a long strain.

Which is the most polar bond?<br><br> a. H-Se <br> b. P-Br <br> c. N-I <br> d. No right answer.
docker41 [41]

Answer:

The answer to your question is: b. P - Br

Explanation:

Difference of electronegativities from the periodic table. The one with the highest electronegativity will be the most polar.

a.

H =  2.2

Se = 2.55

Electronegativity = 2.55 - 2.2 = 0.35

b.

P = 2.19

Br = 2.96

Electronegativity = 2.96 - 2.19 = 0.77

c.

N = 3.04

I = 2.66

Electronegativity = 3.04 - 2.66 = 0.38
