Answer:
The new pressure is 0.167 atm
The correct answer is option A
Explanation:
Step 1: Data given
Volume of the gas = 22.4 L
Pressure of the gas = 0.265 atm
The volume increases to 35.52 L
Step 2: Calculate the new pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 0.265 atm
⇒with V1 = the initial volume = 22.4 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the increased volume = 35.52 L
0.265 atm * 22.4 L = P2 * 35.52 L
P2 = (0.265 atm * 22.4 L) / 35.52 L
P2 = 0.167 atm
The new pressure is 0.167 atm
The correct answer is option A
B. Taxonomy
C. Categorization
D. Spectrometry
Answer:
Yes, this is possible.
Explanation:
It is possible that a cup of tea and teapot filled with tea has the same thermal energy. This often occurs in the real world, when two different thermal energy bodies are placed next to each other.
When two bodies are placed next to each other and these two bodies have different temperatures, there is a transfer of thermal energy between them, which allows them to present the same thermal energy.
With that we can conclude that the teapot received thermal energy from the stove and passed that energy to the tea that was inside it, in this way, tea and teapot had equal thermal energy. This tea, with high thermal energy, was placed in a cup with low thermal energy. The tea promoted a transfer of heat between him and the cup, allowing them to equalize their temperatures and consequently the thermal energy.
In this way, the cup has the same temperature as the tea, which has the same temperature as the teapot.
This equilibrium for a buffer solution: CH3COOH + H2O CH3COO- + H3O + When a small amount of acid is added to this system,
E. [CH3COO-] has increased and pH remains relatively constant.
acidic buffer
A mixture of a weak acid and its salt with a strong base serves as an acidic buffer. The reaction shows that some acetic acids react with the OH– from the base and converts it to water.
HCl and NaCl. Buffer is an equimolar mixture of weak acid and salt with a strong base.
