Term1/13

How do you find out how many battles you have done on ssbb

Definition1/13

Well first you go to options an see data scroll down and explore good luck

Term1/13

Where do trees get carbon dioxide

Definition1/13

Out of the air. There is a lot of carbon dioxide in the air. You exhale carbon dioxide, because your cells use oxygen and turn it into carbon dioxide.

Term1/13

What kind of changes contribute to spontaneity

Definition1/13

An increase in entropy.

Term1/13

What most determines the entropy of a solid

Definition1/13

The crystalline structure of the solid most determine the entropy of a solid.

Term1/13

What does a negative H tell about a reaction

Definition1/13

The reaction is exothermic.

Term1/13

What form a spontaneous reaction at 298 K

Definition1/13

H = 28 kJ/mol, S = 0.109 kJ/(molK)

Term1/13

What is the value for G at 300 K if H 27 kJmol and S 0.09 kJmolK

Definition1/13

G = 0 kJ/mol

Term1/13

How does the entropy change in the reaction 2c3h6g 9o2g 6co2g 6h2og

Definition1/13

The entropy increases

Term1/13

Which is a statement of the second law of thermodynamics

Definition1/13

Entropy tends to increase in a system.

Term1/13

How much energy is required to raise the temperature of 0.2 kg of aluminum from 15C to 18C

Definition1/13

538 J

Term1/13

What describes the entropy change as a solution is made from a liquid to a solid

Definition1/13

S > 0

Term1/13

Definition1/13

Chemical rocket

Term1/13

An aerospace engineer is designing a rocket to have three stages. Which is not a reasonable explanation for this decision

Definition1/13

to simplify the design of the rocket.
