What is the highest energy to which doubly ionized helium atoms (alpha particles) can be accelerated in a DC accelerator with 3

MV maximum voltage
Chemistry

pentagon [3]3 years ago
5 0

Answer:

Highest energy will be equal to 9.6\times 10^{-13}J

Explanation:

Charged on doubly ionized helium atom q=2e=2\times 1.6\times 10^{-19}C=3.2\times 10^{-19}C

It is accelerated with maximum voltage of 3 MV

So voltage V=3\times 10^6volt

Now energy is given by E=qV=3.2\times 10^{-19}\times 3\times 10^6=9.6\times 10^{-13}J

So highest energy will be equal to 9.6\times 10^{-13}J

Answer:       H

               H- C- H

                    H

Explanation:

Lewis structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.

Carbon is an element which belong to group 14. Atomic number of carbon is 6 that means it contains 6 electrons, Thus the electronic configuration is represented as: 1s^22s^22p^2 . Thus the valence electrons are 4.

Hydrogen is an element which belong to group 1. Atomic number of hydrogen is 1 that means it contains 1 electron, Thus the electronic configuration is represented as: 1s^1 . Thus the valence electron are 1.

The four valence electrons of carbon are shared with one valence electron of hydrogen each.

What does the host mean when he says that the acid has "donated a proton" to the water?
weqwewe [10]

Answer:

Option B

Explanation:

As Brønsted-Lowry theory states, acids are the ones that can donate protons.

When a proton is donated, it is released to become medium more acidic.

HCl is a strong acid.

HCl (l) + H₂O (l)  →  H₃O⁺ (aq) +  Cl⁻(aq)

These always reffers to strong acid where the dissociation is 100% completed.

In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.

HA (l) + H₂O (l)  ⇄  H₃O⁺ (aq) +  A⁻(aq)                   Ka
