Why are very few 2+ ions formed in a mass spectrometer?

Chemistry
1 answer:
sattari [20]2 years ago
5 0
A mass spectrometer measures the masses of different substances in molecular form by ionizing them. The molecules are identified by observing their movement in electric and magnetic fields. Most of the ions formed carry a charge of +1. This is because it takes a tremendous amount of energy to remove an electron from an atom that is already positive; the remaining electrons are more tightly held in orbit.

Is material that has a density of 0.2g/ml good for building a bridge or for making couch cushions
lisov135 [29]
D = 0.2 g / ml = 0.2 g / cm³
For example, density of steel is 7.85 g / cm³.
Density of pure water is 1.0 g/cm³. An object which has a density < 1.0 g/cm³ will float in water.
Answer: Material that has a density of 0.2 g/ml ( 0.2 g/cm³ ) is good for making couch cushions.

1. Which graph shows the melting of crystalline solids? Explain your reasoning.
madreJ [45]
(1) The melting of a crystalline solid is best depicted by the second graph. This is because, the second graph shows a horizontal line which means that for a while there was no change in temperature. This zone is the latent heat of fusion. 

(2) The first graph shows the graph of a solid that is just heated but does not experience phase change. However, the second graph shows a solid that changes phase (from crystal/solid to liquid).

How many atoms are in 163 g of calcium?
I am Lyosha [343]
<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

163 g Ca (1 mol / 40.08 g) ( </span>6.022 x 10^23 atoms / 1 mol ) = 2.45 x10^24 atoms Ca
