Answer:
5
Explanation:
Balance the equation in order of C,H,O and then you should be able to find the coefficient
Extrusive Rocks. Igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow.
Answer:
c. ΔH° is positive and ΔS° is positive.
Explanation:
Hello,
In this case, as the Gibbs free energy for a reaction is defined in terms of the change in the enthalpy and entropy as shown below:
Thus, as the reaction becomes spontaneous (ΔG°<0) at temperatures above 1100K (high temperatures), it necessary that c. ΔH° is positive and ΔS° is positive as the entropy will drive the spontaneousness as it becomes smaller than TΔS°.
Best regards.
Answer:
6 J
Explanation: Work done(J) = Force(N) × Distance(m) along the direction of force.
Given, Force=2 N, Distance=3 meters
∴ Wok done (J) = 2 × 3 = 6 J.
