What is the identity of an alpha particle?

Chemistry
2 answers:
Marianna [84]3 years ago
7 0

Answer: It is a helium nuclei.

Explanation: Alpha particles are produced when a larger nuclei decays into smaller nuclei in radioactive decay. Alpha particles have mass number and atomic number as 4 and 2 respectively.

General representation of alpha decay :

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}Y+_2^4\textrm{He}

Alpha particles are identical to helium nucleus. So alpha particles and helium nucleus are infact the same.
its Atomic Mass = 4
its Atomic number = 2
So it has two electrons , two neutrons.
It generally occurs in the decaying of a substance.

the relationship between the heated air particles inside a hot air balloon and the cooler air outside the balloon?
Tamiku [17]
The heated air temperature from inside the balloon more likely rises since it can't escape its trapped resulting in different density from the cooler air, the cooler air from the outside is a bit denser than the heated.

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4
balu736 [363]

Answer:

51.53 grams .

Explanation:

Na₃PO₄    ⇄  3Na⁺¹   +    PO₄⁻³ .

1 mole           3 mole

725 mL of 1.3 M Na⁺  ions

= .725 x 1.3 moles of Na⁺ ions

= .9425 moles

3 mole of Na⁺  is formed by 1 mole of Na₃PO₄

.9425 mole of Na⁺  is formed by .9425/3  mole of Na₃PO₄

Na₃PO₄ needed =  .9425/3  moles = .3142 moles

Molecular weight of Na₃PO₄ = 164

grams of Na₃PO₄ needed = .3142 x 164 = 51.53 grams .

How is primary selection different from secondary succession?
PIT_PIT [208]

Answer:

Explanation:

Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Hope this helped :)
