A cube with sides 3cm.Its mass is 54g. will it sink or float

Chemistry
1 answer:
zloy xaker [14]3 years ago
7 0

Answer:

It will sink.

Explanation:

Density of water=1gm/cc (In CGS)

Volume of cube=l^3 =3^3= 27cc

Mass of cube =54gm

Density of cube=M/V =54/27 =2gm/cc

Here, density of cube is greater than that of water. So, the cube sinks.

during a rising tide, ocean waves often become larger. if the amplitude of a wave increases by a factor of 1.1, by how much does
Sergio039 [100]

Answer:

1.21 times

Explanation:

The energy of a wave is proportional to the square of the amplitude of the wave.

Mathematically:

E\propto A^2

where

E is the energy of the wave

A is its amplitude

In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as

A'=1.1 A

Therefore, this means that the energy of the wave increases by a factor:

E'\propto A'^2=(1.1 A)^2 = 1.1^2 A^2 =1.21 A^2 = 1.21 E

Therefore, the energy of the wave increases by a factor 1.21.

Which change of state is shown in the model?
Romashka [77]
I believe the change of state shown in the model is deposition. 
Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.
One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase changed from gases to solids.

Carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs2 will be generated if 8.0
trapecia [35]
<span>The equation that produces carbon disulfide from the reaction of coke and sufur dioxide is expressed in the balanced equation: c+ 2sO2 = CS2 + 2O2. For every mole of coke reacted, there is one mole of carbon disulfide produced. Hence the answer here is 8 moles of CS2 </span>
