Answer:
<u><em>=355.5K</em></u>
Explanation:
Specific heat, Q = mcΔT
where
- Q= 4250J
- ΔT= change in temp = final temp - initial temp
- c = specific heat capacity = 1.7
- m = mass of substance in grams
[1 mole of Ne = 20g; 2 moles of Ne = 2 × 20 = 40g]
4250 = 40 × 1.7 × (final - 293K)
final - 293k = 4250 / ( 40 × 1.7)
Final temp = 62.5 + 293
<em>=355.5K</em>
I hope this steps are simple to follow and understand.
Answer:
C. is less than 0
Explanation:
The Gibbs free energy (G) of a system is defined as the energy that is used for the work done. The change in Gibbs free energy during a reaction shows the spontaneity and energetics of the reactions.
A reaction will be spontaneous if the change in Gibbs free energy will be negative or less than 0. Reactions with positive Gibbs free energy are non-spontaneous.
Hence, the correct answer is "C. is less than 0".
Answer:
By closely observing the sedimentary rock and the presence of organic materials and mineral grains in sedimentary rocks
Explanation:
The rock cycle explains how the three types of rock are formed over time from each other.
To use a sedimentary rock to prove that the rock cycle is a valid scientific model is by, closely observing the sedimentary rock. when the sedimentary rock is closed observed the principle of superposition will be seen ( i.e. younger segments deposited on top ), the presence of organic materials and mineral grains that can be found in Igneous or Metamorphic rocks can also be seen and this shows that Sedimentary rocks pass through the rock cycle. hence this proves that the rock cycle is a valid scientific model overtime
Answer: this relationship would be mutualism
Explanation: it is a relationship where both species benefit
