Answer:
equal to
Explanation:
The law of conservation of mass tells us that during a chemical reaction, matter cannot be created or destroyed, but it can change from one form to another. This means that while atoms can rearrange themselves into new substances during a reaction, the mass of the reactants and products will be the same.
Answer:
The volume is 310 L
Explanation:
We use the ideal gas formula, with the constant R = 0.082 l atm / K mol. The STP conditions are 1 atm pressure and 273 K temperature. Solve for the formula, V (volume):
PV= nRT ---> V= (nRT)/P
V=( 14 mol x 0,082 l atm /K mol x 273 K)/ 1 atm
<em>V= 313,404 L</em>
Answer:
10
Explanation:
Basically same as last question but the number is before the compound :)
Answer:
The correct option is;
2) Thermal energy increases by a factor of R
Explanation:
The equipartition energy theorem states that when molecules are in a state of thermal equilibrium, particles within the system posses equal average energy with each degree of freedom which can be known as energy due to a state of having a particular temperature or thermal energy given by the relation
= Kinetic energy of translation + Kinetic energy of rotation + Energy of vibration
For a mono-atomic gas, = 3/2·n·R·T
For a diatomic gas, = 5/2·n·R·T
For a solid element, = 3·n·R·T
Therefore, as the temperature is doubled, the thermal energy increases by a factor of R.
