Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>
Answer: 35.4 degrees
Explanation: because it cold
The last option: include all of the known electrons for the adam it represents
that statement is not true because Lewis dot structures only show valence electrons
I’m sorry if I wasted your time but I think it’s alkali metals but I’m
Not sure
<span>energy provided=13.4 eV
energy released=0.7 eV
energy absorbed = 12.7eV
initial energy= -13.6eV [ground state]
final energy = -13.6+12.7 = -0.9 eV
This energy corresponds to n=4 in hydrogen atom</span>
