Hybridization is the process of mixing or two atomic orbitals to become a new atomic orbital. In the given, there are three carbons that are hybridized to sp2. The oxygen labelled 4 is the sp while the 5 is the sp2. The atoms that are being hybridized are the oxygen and the hydrogen.

What is the molarity of the two solutions <br> 0.150 mol of NaOH in 1.80 L of solution

padilas [110]

1 mole of MgS = 24.3 + 32.1 = 56.4 g

35.1 g MgS x 1 mol / 56.4 g = 0.622 mol

M = 0.622 mol / 0.835 L = 0.745 mol/L

To what volume (in milliliters) should you dilute 100.0 mL of a 5.50 M solution of CaCl2 solution to obtain a 0.950 M solution o

Alexxx [7]

Dilution law is given as:

$M_{1}V_{1}=M_{2}V_{2}$ (1)

where, $M_{1}$ = molarity of initial concentrated solution.

$V_{1}$ = volume of initial concentrated solution.

$M_{2}$ = molarity of final diluted solution.

tex]V_{2}[/tex] = volume of final diluted solution.

Volume of initial concentrated solution of $CaCl_{2}$ = 100.0 mL

Molarity of initial concentrated solution of $CaCl_{2}$ = 5.50 M

Volume of final diluted solution of $CaCl_{2}$ = 0.950 M

Put the values in formula (1),

$5.50 M\times 100.0 mL=0.950 M\times V_{2}$

$V_{2} =\frac{5.50 M\times 100.0 mL}{0.950 M}$

$V_{2} =578.9 mL$

Hence, final diluted volume of the solution is $578.9 mL$ .

How does the density of solid water compare to the density of liquid water

jenyasd209 [6]

The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water. What is the exact change in volume of the water when it freezes as ice? Example: Calculate the volume in a 100 g ice cube with a density of 0.92 g per mL.
