Answer:
1. From water vapor to the dry ice;
2. The potential energy is higher before the water vapor condenses;
3. The thermal energy is higher in the 2.0 kg block.
Explanation:
1. The heat flows from the system with high temperature to the system with low temperature. The water vapor is at 298 K, and the dry ice is at 194.5 K.
2. The energy of the molecules is related to the temperature and the physics state. At the gas state, the molecules are more agitated, and the energy is higher than the liquid state. So, when the vapor condenses to a liquid, the energy decreases.
3. The thermal energy can be calculated by:
Q = m*c*ΔT
Where m is the mass, c is the specific heat, and ΔT the variation in the temperature. So, when the mass increase, thermal energy also increases.
To counter the removal of A the equilibrium change by <u>s</u><em>hifting toward the left</em>
<em> </em><u><em>explanation</em></u>
<u><em> </em></u>If the reaction is at equilibrium and we alter the condition a new equilibrium state is created
<u><em> </em></u>The removal of A led to the shift of equilibrium toward the left since it led to less molecules in reactant side which favor the backward reaction.( equilibrium shift to the left)
Answer:
-
Alcohol-related diseases frequently cause low Mg+ levels.
- Mg+ deficiencies must be treated before potassium (K+) deficiencies.
- Mg+ deficiencies often result in low serum potassium (K+)
- Mg++ levels present similarly to calcium (Ca++) levels in the blood.
- Vomiting is not generally seen as a major cause of Mg+ loss
It is scandium or titanium iron chroniclemium vanadium manganese
Answer:
i believe this is a chemical or physical question? well your answer to that is no the element does not change because the gold is still gold it is still physical because you have just cut it into piece it is still gold
Explanation:
lmk if it was helpful :/
