g 8. A hydrogen atom is initially a rest and in the ground state. A proton with kinetic energy 1000 eV scatters off the atom. In

the process the hydrogen atom is ionized. The kinetic energy of the ionized electron is measured to be 15.2 eV and the kinetic energy of the proton produced from the ionization of hydrogen is 4.3 eV. What would be the final kinetic energy of the projectile proton after the collision

Answer:

Explanation:

Ionization energy of hydrogen atom is 13.6 eV . This energy will be provided by energetic proton , the kinetic energy of which is 1000 eV.  The kinetic energy of ionized electron is 15.2 eV . Kinetic energy of proton produced from from the ionization of hydrogen or the nucleus of the hydrogen atom is 4.3 eV . All these energy must have come from kinetic energy of initial proton.

So kinetic energy of projectile proton after collision

= 1000 - ( 13.6 + 15.2 + 4.3 ) eV.

= 966.9 eV .

What can be a personal question about atoms
Damm [24]

Heres a list of questions

1. Define atom.

Atom is the smallest particle of a substance.

2. What are the subatomic particles found in an atom?

The subatomic particles found in an atom are electrons, protons, and neutrons.

3. Define charged particle.

Charged particle is a particle that has an electric charge.

4. Define electric charge.

Electric charge is the physical property of particles such as electrons and protons. Electric charge causes other particles to experience a force.

5. What are the charged particles found in an atom?

Electrons and protons are the charged particles found in an atom.

6. What are the different types of charged particles?

Charged particles are of two types: positive charges and negative charges.

7. What are the negatively charged particles in an atom?

Electrons are the negatively charged particles in an atom.

8. What are the positively charged particles in an atom?

Protons are the positively charged particles in an atom.

9. What is the mass of an electron?

The mass of an electron is 9.107 × 10-31 kilograms.

10. What is the mass of a proton?

The mass of a proton is 1.672 × 10-27kilograms.

11. Define atomic number.

The total number of protons in the nucleus of an atom is called atomic number.

12. Define neutron number.

The total number of neutrons in the nucleus of an atom is called neutron number.

13. Define mass number.

Mass number is the total number of protons and neutrons in the nucleus of an atom.

Mass number can be mathematically written as

Calculate the amount of water required to prepare 500g of 2.5% solution of sugar.
Snowcat [4.5K]

(i) We start by calculating the mass of sugar in the solution:

mass of sugar = concentration × solution mass

mass of sugar = 2.5/100 × 500 = 12.5 g  

Then now we can calculate the amount of water:

solution mass = mass of sugar + mass of water

mass of water =  solution mass - mass of sugar

mass of water = 500 - 12.5 = 487.5 g

(ii) We use the following reasoning:

If       500 g solution contains 12.5 g sugar

Then    X g solution contains 75 g sugar

X=(500×75)/12.5 = 3000 g solution

Now to get the amount of solution in liters we use density (we assume that is equal to 1):

Density = mass / volume

Volume = mass / density

Volume = 3000 / 1 = 3000 liters of sugar solution

Sodium metal reacts with chlorine gas to produce sodium chloride. What mass (grams) of sodium metal would be needed to fully rea
gulaghasi [49]

Answer:

105.8 g of Na would be required

Explanation:

Let's think the reaction:

2Na(s)  + Cl₂(g)  →  2NaCl (s)

1 mol of chlorine reacts with 2 moles of sodium

Then, 2.3 moles of Cl₂ would react with (2.3 .2) / 1 = 4.6 moles

Let's determine the mass of them.

4.6 mol . 23 g/mol = 105.8 g

In which mutation does one base take the place of another?
Neporo4naja [7]

Answer: A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced.

Explanation: I know this is correct just trust me and please mark me as brainiest.
