That would be Protons and Neutrons.
The total pressure is calculated as below
Total pressure = partial pressure of (nitrogen +oxygen + argon gas)
= 587 mm hg + 158 mm hg + 7 mm hg = 752 mmhg is the total pressure
Answer:
Option E!
Explanation:
If we were to draw the lewis dot structure for IBr2 -, we would first count the total number of valence electrons ( " available electrons " ). Iodine has 7 valence electrons, and so does Bromine, but as Bromine exists in 2, the total number of valence electrons would be demonstrated below;

Don't forget the negative on the Bromine!
Now go through the procedure below;
1 ) Place Iodine in the middle and draw single bonds to each of the bromine.
2 ) Add three lone pairs on each of the Bromine's
3 ) Now we have 6 electrons left, if we were to exclude the electrons shared in the " single bonds. " This can be placed as three lone pairs on Iodine ( central atom )!
The molecular geometry can't be linear, as there are lone pairs on the atoms. This makes it bent.
Answer: entropy
Explanation:
Entropy is the measure of degree of randomness or disorder of the system.
Bond energy is the energy possessed by a substance by virtue of its bonding of electrons
Enthalpy is the amount of energy absorbed or released in a chemical reaction.
Internal energy is the energy possessed by a body by virtue of rotational, vibrational and transitional modes.
Heat flow is the phenomenon of thermal equilibrium in which heat flows from hotter body to colder body to maintain equilibrium temperature.
Answer:
hydroperoxyethane
Explanation:
tomsFor the Lewis structure we have to remember that all the atoms must have <u>8 electrons</u> (except for hydrogen). In this structure, we have three types of atoms, Carbon, Hydrogen and Oxygen. So, we have to remember the <u>valence electrons</u> for each atom:
-) Carbon : 4 electrons
-) Hydrogen: 1 electron
-) Oxygen: 6 electrons
We can start with the "
" part. We can put 3 hydrogen bond arroun the carbon. We can use this same logic with "
". Finally for oxygens, we can put it one bond with
and a bond between oxygens with a final bond with hydrogen to obtain <u>hydroperoxyethane</u>.
See figure 1 for further explanations.
