As a bond between a hydrogen atom and a sulfur atom is formed, are the electrons shared or transferred to form a covalent or ionic bond?
Comparing their electronegativities will help determine the type of bond. is the tendency of a bonded atom to attract shared electrons to itself. The difference in electronegativity $(Delta"EN")$ is used...

What is the type of bond in which electrons are shared unequally?
Covalent bonds result from the sharing of electrons between atoms. For homonuclear diatomics, i.e. $H_2$, $He_2^+$, $C_2$, $N_2$, $O_2$, the atoms participating in the molecule have EQUAL and do not...

How many pairs of electrons are shared between the nitrogen atoms in the triple bond of the nitrogen molecule?
Each nitrogen atom has 5 . When two nitrogen atoms bind to form the dinitrogen molecule, each atom provides 3 electrons to give the treble bond, and the remaining pair...

What is the total number of electrons shared in a double covalent bond between two atoms?
Take ethylene $H_2C=CH_2$; around each carbon atom there are 4 . Two of these electrons combine with 2 hydrogen atoms (each with 1 electron) to form $2xxC-H$ bonds. Each carbon...

What symbols are used to represent the charges on atoms in a polar covalent bond? The polarity of the bond? boble type of bond?
Where the $delta$ symbol denotes a little bit of (or partial) positive or negative charge. Dipoles are drawn from positive to negative. The overall dipole moment is the vector sum...

How do you balance $LiAl(OH)_4 + H_2O -> LiOH + Al(OH)_3 + H_2O$?
It's already balanced. Here, let's see what happens when we check what's on each side. $"LiAl"("OH")_4 + cancel("H"_2"O") -> "LiOH" + "Al"("OH")_3 + cancel("H"_2"O")$ $color(green)("Li")color(highlight)("Al")color(blue)(("OH")_4) -> color(green)("Li")color(blue)("OH") + color(highlight)("Al")color(blue)(("OH")_3)$...

Which option contains a $2*g$ mass of sodium atoms....
$1.$ $5.24xx10^22*"sodium atoms?"$
$2.$ $6.022xx10^24*"sodium atoms?"$
$3.$ $3.12xx10^23*"sodium atoms?"$
$4.$ $5.24xx10^22*"sodium atoms?"$
We know that $1*mol$ contains $6.022xx10^23$ individual sodium atoms, and has a mass of $22.99*g$. And thus for $1.$ there is a $2*g$ mass of $Na$. For $2.$ there is...

How many grams of $H_2O$ will be produced if 750 grams of $Fe$ are produced in the equation $Fe_3O_4 + H_2 -> Fe + H_2O$?
We need (i) a stoichiometric equation...... $Fe_3O_4 + 4H_2 rarr 3Fe+4H_2O$ And thus for each mole of iron produced, $4/3$ mol of water are produced consequently...... And (ii) we work...

At standard pressure, $CH_4$ boils at 112 K and $H_2O$ boils at 373 K. What accounts for the higher boiling point of $H_2O$ at standard pressure?
Between water molecules, hydrogen operates, which is a potent intermolecular force. The $H-O$ bond is quite polar, i.e. $""^(delta+)H-O^(delta-)-H^(delta+)$, and the dipoles can align. No such intermolecular force operates between...

How do you calculate the freezing point and the boiling point of the solution formed when 0.150 g of glycerol ($C_3H_8O_3$) is added to 20.0 g of water? $K_(er) (H_2O)$ = 1.86°C, $K_b (H_2O)$ = 0.52 C?
We're asked to find the new freezing point and boiling point of a solution when glycerol is added to water, with known masses and constants. Freezing Point The...
