Vilka [71]3 years ago
8 0

Answer:

It is a fundamental concept that atomic spectra are discontinuous the electron's energy levels are quantized which is a quantum mechanics concept that a system is limited to certain energy states which depends on the particular system being refereed to

Explanation:

Atomic electrons posses only specific energy levels with nothing in between those levels, it can be excited to a higher energy level by gaining the required energy or lose energy in quantized packets to drop to a lower energy level hence the discontinuous spectral lines

The trend in electronegativity is F >Cl >Br; therefore, the most ionic compound (CH2F2) has the lowest boiling point, and
bulgar [2K]

Answer:

False

Explanation:

Increase in polarity of a molecule leads to higher boiling points. The more polar a molecule is, the higher the energy required to breaks intermolecular forces of attraction hence the higher the boiling point. This is the reason why ionic compounds and compounds having polar covalent bonds in them tend to have high boiling points.

1. Take a look at all the elements in period 3. What do you notice? *
Vedmedyk [2.9K]

Answer:

D

Explanation:

beacause all the elements in period 3 has different valence electrons hence you look at the first element in period 3 is sodium which has a valence electron of 1 when you go across the period to the right their valence electron decreases to be negative

imagine that you go into the lab and perform a titration. you measure 40 ml of your analyte and add it to an erlenmeyer flask. t
mote1985 [20]

The Molar concentration of your analyte solution is 1.17 m

<h3>What is titration reaction?</h3>
  • Titration is a chemical analysis procedure that determines the amount of a sample's ingredient by adding a precisely known amount of another substance to the measured sample, with which the desired constituent reacts in a specific, known proportion.

Make use of the titration formula.

The formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base.

if the titrant and analyte have a 1:1 mole ratio. (Molarity is a measure of a solution's concentration represented as the number of moles of solute per litre of solution.)

26 x 1.8 = 40 x M

M = 26 x1.8 /40

M = 1.17

The Molar concentration of your analyte solution is 1.17 m
