Answer:
The rate decreases
Explanation:
When we dissolve a gas in a water, the process is exothermic. This implies that heat is evolved upon dissolution of a gas in water.
Recall from Le Chateliers principle that for exothermic reactions, an increase in temperature favours the reverse reaction. The implication of these is that when the temperature of the gas is increased, less gas will dissolve in water.
Hence increase in temperature decreases the rate of solubility of a gas in water.
Answer:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
sorry if im wrong
Explanation:
Answer:
Explanation:
Applying the Ideal Gas Equation :
Finding n :
- n = 64 g / 32 g/mole (<u>Oxygen is diatomic</u>)
- <u>n = 2 moles</u>
Solving for P :
- P = 2 × 0.0831 × 300 / 10 (<u>Temp. should be converted to K</u>)
- P = 60 × 0.0831
- P = 4.9
∴ The pressure inside the flask in bar is 4.9.
The first one’s 10% and energy is used for movement but i’m not sure what “processes” that would be and the last one is it’s released as heat
Answer:
Sodium atoms due to being smaller in size have high ionization energy and thus, it can't lose electrons easily and is more stable and less reactive. ... Hence, from this it is clear that sodium is less reactive than potassium.
