32 You have two objects made of the same substance. Object 1 is a cube with a mass of 257.7 g. You measure the side of the cube

using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 128.9 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume is 135.8 mL.

The complete question requires that we verify the density of both objects.

The density of object 1 is; 8.1g/cm³ while the density of object 2 is; 8.16g/cm³

<h3>Density of substances</h3>

The density of a substance is given as;

Density = Mass/Volume

Therefore, for Object 1;

  • Volume= l³ (for cubes)

Volume = (3.17)³ = 31.86cm³

Density (1) = 257.7/31.86 = 8.1 g/cm³

For Object 2;

  • Volume = 135.8 - 120 = 15.8mL

  • Volume = 15.8mL = 15.8 cm³

Density = 128.9/15.8

Density = 8.16g/cm³

Which of the following molecules experience dipole-dipole forces as its strongest IMF? A) H2 B) SO2 C) NH3 D) CF4 E) BCl3
Xelga [282]

Answer: NH_3

Explanation:

a) H_2: This  is a non polar covalent compound which are held by weak vanderwaal forces of attraction.

b) SO_2: This  is a covalent compound which is polar due to the presence of lone pair of electrons and are held by dipole-dipole forces of attraction.

c) NH_3: These are joined by a special type of dipole dipole attraction called as hydrogen bond. It forms between electronegative nitrogen atom and hydrogen atom and is the strongest interaction.

d) CF_4: This  is a covalent compound and is non polar which are held by weak vanderwaal forces of attraction.

e)  BCl_3: This  is a covalent compound and is non polar which are held by weak vander waal forces of attraction.

Oxidation Number of fe in fe3o4​
oee [108]

Oxidation number of fe in the compound...,

Let the oxidation number of (Fe) be x

The oxidation number of oxygen(o) is (-2)

; 3x + 4(-2) = 0...where zero is the total charge on the compound(fe3o4)

; 3x = 8...then divide both sides by 3

Oxidation number of fe is( 2.67 )

if a standard die is rolled twice what is the probability of getting a perfect square,then a number that is less than 5.
solniwko [45]
There are three perfect squares in a standard die; 1, 2, 4. If there is two standard dies, then the probability of getting a perfect square is 1/3 x 1/3 = 1/9. 
There are 4 numbers less than 5 in a standard die, making it 1/4 x 1/4=1/16.
