Answer:
Moles of gas collected = 0.952 mole
Explanation:
To calculate the number of moles of the gas collected, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 702 mmHg
V = Volume of the gas = 25.0 L
T = Temperature of the gas = ![22.5^oC=[22.5+273.15]K=295.65\ K](https://tex.z-dn.net/?f=22.5%5EoC%3D%5B22.5%2B273.15%5DK%3D295.65%5C%20K)
R = Gas constant = 
n = number of moles of gas = ?
Putting values in above equation, we get:
<u>Moles of gas collected = 0.952 mole</u>
Answer:
In a primary cell, two electrodes (one of copper and other of zinc) of metal atoms are used. These electrodes are dipped in an electrolyte solution that causes the metals to produce their respective positive and negative ions.
In this way, the flow of charges takes place and supply the electricity to the source.
Unlike a primary cell, a dry cell contains paste of an electrolyte instead of the solution. The contents of electrolyte paste react with each other through a chemical process and convert the chemical energy into electrical energy.
Weak acids contain: acetic acid, citric acid& carbonic acid
I only know those three
And strong acids are:
Sulfuric acid, nitric acid, hydrochloric acid
Hey there,
<span>A scientist triples the temperature of a gas at constant pressure. By what factor does the gas’s volume change?
I believe that when the scientist triples the temperature of the gas at a certain and constant pressure, the factor of the gas volume would change most likely with the double amount of pressure that the scientist put in the first place.
