Answer:
Climate is long time intervals and weather is short time intervals
Explanation:
In order to find out the number of electrons present in s orbital of Phosphorous we have to write the electronic configuration of phosphorous.
As the Atomic number of Phosphorous is 15 so it will have 15 electrons in neutral state. So,
P = 15 = 1s², 2s², 2p⁶, 3s², 3p³
Now analyzing electronic configuration, we found that it contains 3 s orbitals, i.e. 1s, 2s and 3s, and each s orbital is completely filled with two electrons each.
Result:
Therefore, a total of six electrons are present in all s orbitals of neutral Phosphorous Atom.
Answer:
b. Bakelite
Explanation:
Bakelite -
Bakelite is a form if plastic , and is the very first plastic synthesized .
The handles of the cooking utensils are used to hold the utensil firmly , and hence need not turn hot while cooking , and need to be strong enough to take care of the food .
Hence , the handle should be of the material which is poor conductor of heat and strong .
Hence , bakelite is used for making the handle.
The scientist should make a new hypothesis and do a new experiment! That is what I say!
Answer: 41.2 atm
Explanation
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
The maximum pressure (in atm) that will be attained in the tank before the plug melts and releases gas is 41.2
