Nitrate 2 , Hydrogen Oxygen , and Carbon Oxide
Answer: it would be 0.026 moles
Explanation: PV=nRT, P is the pressure of gas, V is the volume it occupies n is the number of moles of gas present in the sample, R is the universal gas constant which is equal to 0.0821 atm L/mol K and T is the absolute temperature of the gas
Answer:
its a
Explanation:
because a mutation is a change and a change can be a mutation
Answer:
a generator that allows them to convert kinetic energy into potential energy
Explanation:
Rescue workers can accomplish this by using a generator that allows them to convert kinetic energy into potential energy. Such as a crank generator, with these, they spin a crank with their hands and the generator takes that kinetic energy that is building up through the work that the rescuer is exerting and converts it to potential electric energy that can properly be used to provide energy to the batteries for their equipment. This is what is generally used for situations such as what rescuers go through when there is no electricity around.
The given solution is a mixture of 
and 
. It acts as a buffer as it is a combination of the weak acid 
and it's conjugate base 
.
![[Acid] = [HCO_{3}^{-}]=1.0 M](https://tex.z-dn.net/?f=%5BAcid%5D%20%3D%20%5BHCO_%7B3%7D%5E%7B-%7D%5D%3D1.0%20M)
![[Base] =[CO_{3}^{2-}]=0.1 M](https://tex.z-dn.net/?f=%5BBase%5D%20%3D%5BCO_%7B3%7D%5E%7B2-%7D%5D%3D0.1%20M)
pH of the buffer solution can be calculated from Hendersen-Hasselbalch equation as below:
![pH=pK_{a}+log\frac{[CO_{3}^{2-}]}{[HCO_{3}^{-}]}](https://tex.z-dn.net/?f=pH%3DpK_%7Ba%7D%2Blog%5Cfrac%7B%5BCO_%7B3%7D%5E%7B2-%7D%5D%7D%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D)
pH = 10.33+(-1)
= 9.33
