Answer:

Blues

Explanation:

Colors of Rainbow => ROYGBIV

Red    Orange   Yellow   Green   Blue   Indigo   Violet

low energy  => => => => => => => => => => high energy

low frequency => => => => => => => => =>  high frequency

long wavelengths => => => => => => => => short wavelengths

Note: All L's on the Left => low, low, long; other end are opposites.

The first IE of neon (atomic number 10) is significantly higher than that of argon (atomic number 18) but significantly
lbvjy [14]

Explanation:

Different atoms binds their outermost shell electrons with different amount of energy.

The amount of energy required to remove an electron from an atom is the ionization energy.

  • Ionization energy measures the readiness of an atom to lose electrons.
  • From the given problem, we can infer that in group O the ionization energy decreases down the group.
  • Helium has the highest ionization energy.
  • Down a group on the periodic table, ionization energy decrease because:
  1.  atomic radii increases down the group.
  2. there is an increasing shielding/screening effect of inner shell electrons on the outermost shell electrons.

The amount of gas that occupies 36.52 L at 68.0°C and 672 mm Hg is __________ mol.
ASHA 777 [7]
We assume that this gas is an ideal gas. We use the ideal gas equation to calculate the amount of the gas in moles. It is expressed as:

PV = nRT
(672) (1/760) (36.52) = n (0.08206) ( 68 +273.15)
n = 1.15 mol of gas

Hope this answers the question. Have a nice day.

Calculate the molarity of 13.1 g of NaCl in 727 mL of solution
valentina_108 [34]

Answer:

The molarity of the solution is 0,31 M

Explanation:

We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)

Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g

58, 5 g-----1 mol NaCl

13,1 g ---------x= (13,1 g x 1 mol NaCl)/58, 5 g= 0, 224 mol NaCl

727 ml solution------ 0, 224 mol NaCl

1000ml solution------x= (1000ml solutionx0, 224 mol NaCl)/727 ml solution

x=0,308 mol NaCl---> <em>The solution is 0,31 molar (0,31 M)</em>
