Answer:
Explanation:
The instantaneous velocity of a point mass that executes a simple harmonic movement is given by:
Where:
Express the amplitude in meters:
The angular frequency can be found using the next equation:
Using the data provided:
At the equilibrium position:
Answer:
Explanation:
To solve this problem we will use the Ideal Gas Law, which forms the following formula
Where
= Pressure of Gas
= Volume of Gas
= Moles of Gas
= Constant = 0.0821 atm L/mol K
= Temperature of Gas
There are two states to consider
State 1 is given
= 0.741 atm
= 112 mL
= unknown
= 0.0821 atm L/mol K
= 300K
State 2 is based on Standard Room Temperature Pressure (STP) which are fixed values
= 1 atm
= unknown
= unknown
= 0.0821 atm L/mol K
= 273.15K
Since this is the same mass of gas it can be reasoned that the moles of gas are the same. We rearrange the Gas Law Formula to the following
We input the values and equate the formulas for both states by substituting the value of n
Answer
The first energy level can be occupied by a maximum of 2 electrons.
Each hydrogen atom has only one electron which occupies the first energy level.
Therefore, two hydrogen atoms will each share this one electron and form a covalent bond. By doing this (sharing electron), each of the two atoms will now be having 2 electrons (its original electron + the shared one from the other atom) and are now both stable forming a hydrogen molecule.
