Which orbital would the electron of a ground state hydrogen atom occupy? 1s 1p 2p none of the above 0s?

1 answer:

6 0

From the periodic table, we can see that:
At ground state, the hydrogen atom has one electron
Based on the electronic configuration, at ground state this electron should be occupying the orbital (1s)

Since (1s) is not one of the choices, therefore, the answer is "none of the above"

A hot-air balloon is filled with air to a volume of 3000 m3 at 750 torr and 21°C. The air in the balloon is then heated to 60.°C

Answer: 1.47

Explanation:

The combined gas equation when pressure is constant:

$\frac{V_1}{n_1T_1}=\frac{V_2}{n_2T_2}$

where,

$n_1$ =original number of moles of air in the balloon = ?

$n_2$ = number of moles of air in the heated balloon = ?

$V_1$ = initial volume of gas = $3000m^3$

$V_2$ = final volume of gas = $5000m^3$

$T_1$ = initial temperature of gas = $21^oC=273+21=294K$

$T_2$ = final temperature of gas = $60^oC=273+60=333K$

Now put all the given values in the above equation, we get the final pressure of gas.

$\frac{3000}{n_1\times 294K}=\frac{5000}{n_2\times 333K}$

$\frac{n_2}{n_1}=1.47$

Therefore, the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon is 1.47

Answer:

The human body is composed of the different systems or controlling parts, and among these organs the brain and spinal cord functions for the regulation of nerves and for the regulation of communication inside the human body. As, there are small basic units or cells called as neurons which makes up the basic framework for the functioning of this nervous system.

Now, each of our body's function is either voluntary or involuntary in nature. As, they arise to having a chemical imbalance or in other words a synapse inside the structure or body of the neurons. While, all of the actions are full controlled by the central nervous system but some of them are controlled by the processing system which are called as the voluntary changes or actions. And on the other those which are not controlled all by the human body, as such actions are said to be involuntary in nature.
While, the nervous system outside the more organized and becomes more complex when we analyze the nervous system outside the CNS and such neural system is then termed as the peripheral nervous system.
Some of the response are quick and do not require any longer for the body to react in and such body responses are termed as the autonomic fight-or-flight responses. As, such functions or changes inside the body posture and system included inside the sympathetic relaxing responses.
