Missing question: Express the salt concentration in kg/m³.
Answer is: the salt concentration is 9.8 kg/m³.
m(NaCl) = 9.8 g ÷ 1000 g/kg.
m(NaCl) = 0.0098 kg.
V(solution) = 1 L = 1 dm³.
V(solution) = 1 dm³ ÷ 1000 dm³/m³.
V(solution) = 0.001 m³.
d(solution) = m(NaCl) ÷ V(solution).
d(solution) = 0.0098 kg ÷ 0.001 m³.
d(solution) = 9.8 kg/m³.

The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.

<h3>How do molecules act at different temperatures?
</h3>

In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:

Cold molecules:

  • Molecules together.
  • Molecules with little movement.

Hot molecules:

  • Separate molecules.
  • Molecules with active movement.

A simple example to understand this behavior of molecules is water because:

  • When water is frozen its molecules are almost static and close together.
  • When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.

A piece of lead loses 78.0 J ofheat and experiences a decrease in temperature of 9.0C the specific heat of lead is .130J/gC what
Ratling [72]
The  mass of  the piece  of  lead   is    calculated  using the  below  formula
Q(heat)= mC delta T

Q = 78.0  j
M=mass =?
C=specific heat capacity (   0.130 j/g/c
delat T=change in temperature =  9.0 c

by  making  M  the  subject  of  the formula
M = Q/ c delta T

M=  78.0 j/ 0.130 j/g/c  x  9.0 c =  66.7 g  of  lead

How would I Determine the number of moles in 3.51 x 10^23 formula units of CaCl2
Andrej [43]

Answer:

by using this formula you will get it

Explanation:

number of mole = number of particles÷ Avogadro's number

n=3.51×10^23÷ 6.02×10^23

n = 0.58 moles

Describe the three main types of plate boundary interactions:
bulgar [2K]

Answer:

In the explanation

Explanation:

Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.

Convergent: When two plates are moving towards each other.

If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.

If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.

Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

Hope this helps!
