27,000,000,000 or 2.7e10
Both mean the same
Answer:
Tectonic plates
Explanation:
Tectonic plates shifting is long term which creates a short term Earthquake, I hope this helped.
Answer:
b. ΔS° > 0, ΔH° < 0
Explanation:
According the equation of Gibb's free energy -
∆°G = ∆°H -T∆°S
∆°G = is the change in gibb's free energy
∆°H = is the change in enthalpy
T = temperature
∆°S = is the change in entropy .
And , the sign of the Δ°G , determines whether the reaction is Spontaneous or non - Spontaneous or at equilibrium ,
i.e. ,
if
- Δ°G < 0 , the reaction is Spontaneous
- Δ°G > 0 , the reaction is non - Spontaneous
- Δ°G = 0 , the reaction is at equilibrium
The reaction has the value for ∆°H < 0 i.e. negative, and ∆°S > 0 i.e. , positive
Now ,
∆°G = ∆°H -T∆°S
= ( - ∆°H ) - T( + ∆°S )
= ( - ∆°H ) - T( ∆°S )
∆°G = negative
Hence ,
Δ°G < 0 , the reaction is Spontaneous .
Answer:
cobalt (Co) is the correct answer.
Explanation:
The is most likely to bend without breaking element is cobalt because of the following properties.
- Cobalt is a ferromagnetic metal.
- Cobalt is a brittle and hard element.
- cobalt is not a nonmetal, it is a metal and metals are malleable and ductile means they can bend without breaking.
Hence Cobalt in their solid form they can be easily bent and changed into thin films without breaking
