When a beta particle<span> is emitted from the </span>nucleus<span> the </span>nucleus<span> has one more proton and one less neutron. This means the </span>atomic<span> mass number remains unchanged and the </span>atomic<span> number increases by 1.
Best answer :
</span><span>b. the number of electrons in the atom increases by one as the beta particle leaves the nucleus and joins the valence electrons</span>
NH₃ would. This is because of the fact that ammonia is a molecular gas while the other options are ionic crystals. Crystals increase in solubility when the temperature increases while gases increase in solubility while temperatures deceases.
I hope this helps. Let me know in the comments if anything is unclear or if you want me to explain anything is more detail.
Answer:
<h2>The answer is 63.24 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 62 mL
density = 1.02 g/mL
The mass of the water is
mass = 1.02 × 62
We have the final answer as
<h3>63.24 g</h3>
Hope this helps you
The mass of 5.2 x 10^22 manganese atoms in grams would be 635.784 grams.
What is Avogadro's constant?
Avogadro's number tells us how many particles are in one mole (or mol) of a substance. <u>Electrons</u><u>, molecules, or atoms</u> could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³ mol⁻¹. Avogadro's number tells us how many particles are in one mole (or mol) of a substance. <u>Electrons, molecules, or atoms </u>could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³.
Computation of mass
Avogadro calculated that every material had 6.022 x 10^23 atoms per mole.
5.2 x 10^22 atoms of Mn would contain how many moles?
= 6.022 x 10^23 /1 x 5.2 x10^22
=11.58 moles
Mn mass equals 11.58 moles multiplied by 54.9
= 635.784 grams

Answer:
The third option
Explanation:
If people have found more volcanic rock layers in the past that would mean that volcanic activity was more common in the past.
