The formula for pH is -log [H+] where [H+] is the Molarity. Therefore if you plug the numbers in your answer will be 2.77
Answer:
Does a reaction occur when aqueous solutions of copper(II) nitrate and calcium chloride are combined?
Explanation:
The given reaction is an example of a chemical double displacement reaction.
The mutual interchange of the ions takes place.
The balanced chemical equation of the reaction is:
All the products formed are also highly soluble.
So, all the ions are spectator ions.
Hence, all will cancel with each other and ions remain in the net ionic equation and hence, the reaction does not take place.
The particle that is identical to a high energy electron is known as a beta particle.
The formula of this reaction is 2C3H7OH + 9O2 = 6CO2 + 8H2O. So there is 0.45 mol O2 for combustion of 0.1 mol 1-propanol. At STP, 0.45 mol has volume of 10.08 dm3. The room temperature usually is 20℃. According to the formula V1/T1=V2/T2, you can get the finally volume is 10.8 dm3.
A) It would increase.
Explanation:
The gravitational force between the two masses will increase.
This is in compliance with universal law of gravitation proposed by newton.
Newton's law of universal gravitation states that "the gravitational force of attraction between two masses is directly proportional to the product of the masses and inversely proportional to the square of the distance them".
From law, we can establish that the gravitational force is directly proportional to the product of the masses between two bodies.
The higher the mass, the higher the gravitational force.
