Non-polar Covalent bonding is the type of bonding that takes place when two atoms share a pair of electrons with each other. In order to form a molecule, these two electrons are glued to one or more atoms. One important contribution of non-covalent bonding is the oxygen we breathe. On the other hand, polar covalent bonding happens when a pair of electrons are being shared unequally because one of the atoms spends way too much time with another electrons rather than with the atoms.
Radio waves. hope this helps my friend
Answer:
OptionA. 2C4H10 + 13O2 —> 8CO2 + 10H20
Explanation:
Butane burns is air (O2) according to the equation:
C4H10 + O2 —> CO2 + H20
Considering the equation, it is evident that it not balanced. Now let us balance the equation as shown below;
There are a total of 4 carbon atoms on the left and 1 carbon atom on the right. It can be balanced by putting 4 in front of CO2 as shown below:
C4H10 + O2 —> 4CO2 + H20
Next, there are 10 hydrogen atoms on the left and 2 hydrogen atoms on the right. Therefore to balance it, put 5 in front of H2O as shown below:
C4H10 + O2 —> 4CO2 + 5H20
Now, there are a total of 13 oxygen atoms on the right and 2 at the left. To balance it, put 13/2 in front of O2
as shown below
C4H10 + 13/2O2 —> 4CO2 + 5H20
Now we multiply through by 2 clear off the fraction and we obtained:
2C4H10 + 13O2 —> 8CO2 + 10H20
Answer:
2193.8 PSI is the pressure in the tank
Explanation:
We apply the Ideal Gases Law to solve this:
P . V = n . R . T
T° is the temperature in K, so we must do the conversion:
35°C + 273 = 308K
P . 1650L = 9750 mol . 0.082 L.atm/mol.K . 308K
P = (9750 mol . 0.082 L.atm/mol.K . 308K) / 1650L → 149.24 atm
Let's make the conversion:
1 atm = 14.7 PSI → 149.24 atm . 14.7 PSI / 1 atm = 2193.8 PSI
Out of those ones, im sure its c. It's definitely not b or d. It allows motion but also protects vital organs. :)
