Answer: Alpha radiation
Explanation: Alpha decay : When a larger radioactive nuclei decays into smaller nuclei by releasing alpha radiation, the mass number and atomic number is reduced by 4 and 2 units respectively.
Beta decay : When a larger radioactive nuclei decays into smaller nuclei by releasing beta radiation, the atomic number is increased by 1 unit.
Gamma decay : When a larger radioactive nuclei decays into smaller nuclei by releasing gamma radiation, the mass number remains same.
Volume= mass divided by density
V= m/d
55/3.23
= 17.03
Solution..
---------------
Let's calculate the mass of CO₂.
We have (12+(16*2))
= 12+32
=44gmol¯¹..
a. What is the percent by mass of carbon?
Mass of carbon /mass of CO₂ × 100%
12/44 × 100%
=27.3%...
b. What is the percent by mass of oxygen?
Mass of oxygen/mass of CO₂ × 100%
(2×16)/44 × 100%
32/44 × 100%
=72.7%....
To check.. You'll add this two percentage compositions together and see of it gives 100%... If it does then we're good...
27.3%+72.7% = 100%.... Checked..
Hope this helped....?
hydrogen bond, nucleotides in a base pair complement each other which means their shape allows them to bond together with hydrogen bonds.
Whether an element is classified as a major or as a trace mineral is determined by
"<span>
the amounts daily required by the body".

Calcium, magnesium,
phosphorus, potassium, chloride and sulfur are all examples of the major
minerals and these are the minerals a body needs in large quantity as opposed
to include iron, copper, zinc, manganese, fluoride, selenium and cobalt, which
are all trace minerals and are needed in very little quantity.
