Polar<span> bonds happen when two atoms form a </span>molecule<span> using a covalent </span>bond<span>. When the two atoms share electrons, there is also a change of electron density. If the electrons are not shared equally, then there will be a partial </span>ionic<span> charge. ... The greater the </span>difference<span> in these charges, the more </span>ionic<span> the </span>bond<span> will be</span>
Answer:
Products are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state. This process results in the consumption of the reactants.
Explanation:
hope this helps if not let me know have a great day
In the second energy level, the highest energy subshell is 2p. The subshells are shown by the orbital quantum numbers.
There are four sets of quantum numbers that describe an electron in an atom which are;
- Principal quantum number
- Orbital quantum number
- Magnetic quantum number
- Spin quantum number
The values of the orbital quantum number which shows the energy subshell in which an electron is found must take on values from 0 to (n - 1).
Having said that, for an atom with more than one electron, the highest energy subshell in the second energy level corresponds to l =1 which is the 2p orbital. Remember that s p d f corresponds to 0 1 2 3 .

The heat will flow from copper to aluminum because Cu is at higher temperature. The heat liberated is -7.60kJ
When two metals at different temperatures are kept in contact, heat flows from hotter metal to colder metal until thermal equilibrium is reached.
Here Copper is at a temperature of 60 degree Celsius and aluminum is at 40 degree Celsius. Thus, heat will flow from Cu to Al.
In order to calculate the amount of heat liberated following calculations are required.
m1=262 g
T1=87 oC
Cp=0.385 J/g oC
T2=11.8 oC
The heat liberated can be expressed as follows:
Q=mCp(T2-T1)
Q=262 g*0.385 J/goC(11.8-87)oC
Q=-7585 J
=-7.60kJ
