Electrospray ionization mass spectroscopy often results in analyte molecules fragmenting

FALSE

<u>Electrospray ionization mass spectroscopy</u>

It is a technique using electrospray to generate ions for mass spectrometry by applying high voltage to the liquid.

Electrospray ionization is a soft ionization technique.

It is used for production of gas phase ions.

The process of Electrospray ionization mass spectroscopy

1. dispersal of a fine spray charge droplets

2. solvent evaporation

3. ion ejection from highly charged droplets

What is the empirical formula of a compound that contains 27.0% s

eduard

Answer:

Empirical formula of the compound = SOCl₂

Explanation:

QUESTION:What is the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass?

The empirical formula of a compound is its simplest formula. It tells us

* The component element present in a molecule of the compound.

* The ratio in which these elements are combined together, i.e mole ratio.

To calculate the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass. ( Relative atomic mass of S=32gmol⁻¹, 0=16gmol⁻¹, Cl=35.5gmol⁻¹)

Sulphure S, Oxygen O, Chlorine Cl

percentage by mass: 27.0% 13.4% 59.6%

Step 1:

Divide by their relative

atomic mass: 27.0/32.0 13.4/16.0 59.6/35.5

⇒⇒⇒⇒⇒⇒⇒⇒⇒ 0.844 0.838 1.679

Step 2:

Divide by the

smallest mole ratio: 0.844/0.838 0.838/0.838 1.679/0.838

∴ 1 : 1 : 2.

from the analysis above, the compound contains Sulphur, Oxygen and Chlorine in the ratio of 1:1:2.

∴ Empirical formula of the compound = SOCl₂

If the star Alpha Centauri were moved to a distance 10 times farther than it is now, its parallax angle would

steposvetlana [31]

Answer:

B. get smaller

Explanation:

The parallax angle of a star measured with respect to the Earth is inversely proportional to the distance of the star from the Earth:

$\theta = \frac{1}{d}$

where

$\theta$ is the parallax angle, measured in arcsec

d is the distance between the star and the Earth, measured in parsec

Therefore, if the star Alpha Centauri is moved farther from Earth, then d increases, and therefore the parallax angle will get smaller.

Noaptea, aflându-te într-o odaie întunecată, observi pe peretele opus ferestrei deplasarea petelor luminoase provenite de la far

alina1380 [7]

Answer:

The car evidently moved in the South-North direction.

Mașina se deplasa în mod evident în direcția Sud-Nord.

Explanation:

English Translation

At night, in a dark room, you notice on the wall opposite the window the movement of light spots from the headlights of a car in a south-north direction. In what direction did the car move?

Solution

Light rays fall obliquely on walls but move in the same direction as the car's direction of travel. And from the question, it is stated that the light rays move in the south-north direction, hence, the car in question, moved in the South-North direction too.

In Romanian/In limba romana

Razele de lumină cad oblic pe pereți, dar se mișcă în aceeași direcție ca direcția de deplasare a mașinii. Și din întrebare, se precizează că razele de lumină se deplasează în direcția sud-nord, prin urmare, mașina în cauză se deplasa și în direcția Sud-Nord.

Hope this Helps!!!
