Use the formula for second order reaction:
C = concentration at time t
C0 = initial conc.
k = rate constant
t = time

Answer:
Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus.
Answer:
1.25 Moles
Explanation:
1.25 moles of solute
Explanation:
Molarity is defined as the number of moles of solute per liter of solution.
Molarity = moles of solute / liter of solution
We are given the molarity and volume, both of which have the correct units. All we have to do is rearrange the equation to find the number of moles. You can do this by multiplying both sides of the equation by the volume to cancel it out on the right hand side. Afterwards, you should end up having the volume multiplied by the molarity equaling the number of moles of solute like so:
Moles of solute = Molarity * Volume
2.5M HCl * 0.5 L = 1.25 moles of HCl
I hope this made sense.
Answer:
Volume = 4.28L
Explanation:
Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:
So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.
