D because strong bases ( and 14 is a strong base ) will make a strong acid neutral
Hear n = 1000 to n = 2 pairs of quantum states of hydrogen has the biggest energy difference between the states
A quantum state is a mathematical concept used in quantum physics that gives a probability distribution for the results of each potential experiment on a system. All that can be predicted about the behaviour of the system is exhausted by knowledge of the quantum state and the laws governing the system's evolution across time. Another quantum state is a combination of quantum states. All other quantum states are known as mixed quantum states, whereas pure quantum states are those that cannot be described as a combination of other states. A ray in a Hilbert space over the complex numbers can represent a pure quantum state, but density matrices, which are positive semidefinite operators acting on Hilbert spaces, can represent mixed states.To know more about ray, visit to: -brainly.com/question/17491571#SPJ4
If ALL individuals of a species were not able to have offspring, then that species would eventually become extinct.
Answer:
Volume of water
Initial temperature of the solution
Final temperature of the solution
Mass of NH₄Cl
Explanation:
There are two heat transfers involved in this experiment.
Heat of solution of NH₄Cl + heat lost by water = 0
q₁ + q₂ = 0
nΔH + mCΔT = 0
nΔH = -mCΔT
ΔH = -mCΔT/n
So, you must measure
- the volume of water (you will probably use its density to calculate its mass)
- the initial and final temperatures of the solution (to calculate ΔT)
- the mass of NH₄Cl (to calculate the number of moles)
You will probably assume that the specific heat capacity of the solution is the same as that of water, so you won't be measuring it.
