Answer:

3Ca₍s₎ + 2FeCl₃ -------------------------------------------------------------> 3CaCl₂ + 2Fe₍s₎.

Explanation:

Iron(III) chloride is also known as Iron trichloride and it has the molar mass value of 162.2 g/mol and density of 2.9 g/cm³.

The balanced equation for the chemical reaction between solid calcium and iron (III) chloride is given below as:

3Ca₍s₎ + 2FeCl₃ -------------------------------------------------------------> 3CaCl₂ + 2Fe₍s₎.

This kind of chemical reaction is known as single displacement reaction or single replacement reaction.

Individual particles move with the wave.

MArishka [77]

Answer:

No.

Explanation:

No, individual particles do not move with the wave, it only oscillates back and forth its mean position. The particles in the medium transfer its energy to their neighboring particles and in that way the energy moves in the form of wave. The particles only vibrates on its means position instead of moving from one place to another. So we can conclude that Individual particles do not move with the wave.

46. True or false. Chemical reactions do not involve changes in the chemical bonds that join

Naddika [18.5K]

Answer:

Chemical reactions do not involve changes in the chemical bonds that join

atoms in compounds :

False

Explanation:

Chemical reaction are the reaction in which old bonds break and new bonds are formed . The formation of new bond result in formation of new compounds . This happen because new bond are result of linking different atoms by the bond.

For example : Water formation from Oxygen and Hydrogen is a chemical process :

$2H_{2}+O_{2}\rightarrow 2H_{2}O$

Original(old) bonds are :

H-H bond in H2 and O-O bonds in O2

In H2 = Hydrogen is joined to Hydrogen

IN O2 = Oxygen is joined to oxygen

New Bonds =

O-H bonds in water (H2O)

Oxygen is joined to hydrogen = New Bond formation

Hence,

Chemical reactions do involve changes in the chemical bonds that join

atoms in compounds

How many kilojoules are needed to convert 77.5 grams of ice at -8.00°C to water at 95.0°C?

Over [174]

Q=mcθ
m= 0.0775 kg
c= 4184 J·kg−1·K−1.
θ= T(final) - T(initial), 95-(-8)

Q=33398.78 J so kJ divide 1000

= 33.39878 kJ
