Answer:
3
Explanation:
The plates are moving away from each other
The idea here is that one mole of any ideal gas that is kept under standard temperature and pressure, STP, conditions will occupy 22.4 L
<h2>
Answer:</h2>
CH4 + 2O2 → CO2 + 2H2O
<h2>
Explanation:</h2>
10 grams of methane reacts with 40g of oxygen in the air. This means that mass from the oxygen in the air is also present in the carbon dioxide, so the mass can appear to increase, whereas in reality it is the mass of the oxygen that has caused the increase.
This reaction obeys the law of conservation of mass. Even though it may to appear so until balanced, all reactions follow the law.

The molar solubility is 7.4× M and the solubility is 7.4× g/L .
Calculation ,
The dissociation of silver bromide is given as ,
→ +
S
- S S
Ksp = [ ] [ ] = [S] [ S ] =
S = √ Ksp = √ 5. 5× = 7.4×
The solubility =7.4× g/L
The molar solubility is the solubility of one mole of the substance.
Since , one mole of is dissociates and form one mole of each and ion . So, solubility is equal to molar solubility but unit is different.
Molar solubility = 7.4× mol/L = 7.4× M
