Answer:

C=0.596\frac{J}{g\°C}

Explanation:

Hello there!

In this case, according to the first law of thermodynamics it is possible to compute the gained heat by the water as shown below:

Q=\Delta U+W\\\\Q=9185J+346J=9531 J

Thus, it is possible to solve for the specific heat of the gas as shown below:

Q=mC\Delta T\\\\C=\frac{Q}{m\Delta T}=\frac{9531J}{80.0g*(225-25)\°C}\\\\C=0.596\frac{J}{g\°C}

Best regards!

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 :

<u>False</u>

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,

<u>Chemical reactions do involve changes in the chemical bonds that join </u>

<u>atoms in compounds</u>

The frequency of an x-ray wave is 3.0 x 1012 MHz. Its wave speed is 3.0x 108 m/s. Calculate the wavelength of the x-ray wave bel
elena55 [62]

Answer:

λ = 1*10⁻¹⁰m

Explanation:

Frequency (f) = 3.0*10¹²MHz = 3.0*10¹⁸Hz

Speed (v) = 3.0*10⁸m/s

Speed (v) of a wave = frequency (f) * wavelength (λ)

V = fλ

Solve for λ,

λ = v / f

λ = 3.0*10⁸ / 3.0*10¹⁸

λ = 1*10⁻¹⁰m

λ = 0.
