5L O2 x 1 mol O2/ 22.4L O2 x 2 mol H20/ 1 mol O2 x 22.4L H20/ 1 mol H20 = 10 L H2O
For future reference though, since its at STP that means that the coefficient are in proportion. Since oxygen has a coefficient of 1 and water has a coefficient of 2 for every 1 liter of oxygen there is 2 liters of water. Hence you started with 5 liters and ended with 10
Each molecule of Sr₃(PO₄)₂ contains 3 moles of Sr
So 3 moles of Sr⁺² ions are in one mole of Sr₃(PO₄)₂.
Answer: -
Solubility of a substance depend on the balance of intermolecular forces between the solvent and solute, and the entropy change that accompanies this process.
Temperature and pressure also plays a role in solubility.
A solution having Group 1 cations like lithium, sodium, potassium etc are always soluble.
A solution having NH₄⁺ is soluble.
All salts with anion as nitrates, acetates, chlorates, and perchlorates are soluble in water.
Answer:
Option C. 10m/s
Explanation:
Data obtained from the question include:
Wavelength = 5m
Frequency = 2Hz
Velocity =..?
Velocity of a wave is related to the wavelength and frequency by the following equation:
Velocity = wavelength x frequency
With the above equation, we can easily calculate the velocity of the ocean wave as follow:
Velocity = 5 x 2
Velocity = 10m/s
From the calculation made above, we can see that the velocity of the ocean wave is 10m/s.
