<u>Answer:</u> The daughter element produced will be _{85}^{217}\textrm{At}

<u>Explanation:</u>

Alpha decay is defined as the process in which a heavier nuclei decays into lighter nuclei while producing alpha particle. The alpha particle released carries a mass of 4 units and a charge of +2 units.

The mass number of the element produced is reduced by 4 units and the atomic number of the element produced is reduced by 2 units.

The chemical equation representing the alpha decay of francium-221 follows:

_{87}^{221}\textrm{Fr}\rightarrow _{85}^{217}\textrm{At}+_2^4\alpha

Hence, the daughter element produced will be _{85}^{217}\textrm{At}

Which object(s) formed last in our solar system?
AnnyKZ [126]

Long year ago In space, gravity attracts dust and gas together which created the young solar system. It pulled low-density cloud together to produce initially the solar nebula. These clouds are made of interstellar gas and dust.  

The sun formed first from these nebula and dust.

Planetesimals is just a process indicates the formation of Earth and the other planets from concentrations of dust and diffused matter in the solar system.

Inner planets are the planets located closure to the sun in comparison to outer planets. These inner planets are mercury, venus, earth and mars. Thus, 4.5 billion year ago Inner planets formed at last.

Magnetite is a binary compound containing only iron and oxygen. the percent, by weight, of iron is 72.360%. what is the empirica
hram777 [196]
Answer is: <span>c. Fe</span>₃<span>O</span>₄<span>.
</span>ω(Fe) = 72,360%.
ω(O) = 100% - 72,36% = 27,64%.
For example, if we the mass of compound is 100 g:
m(Fe) = 72,36 g.
n(Fe) = m(Fe) ÷ M(Fe).
n(Fe) = 72,36 g ÷ 55,85 g/mol.
n(Fe) = 1,296 mol.
n(O) = 27,64 g ÷ 16 g/mol.
n(O) = 1,727 mol.
n(Fe) : n(O) = 1,296 mol : 1,727 mol.
n(Fe) : n(O) = 1 : 1,33 or 3 : 4.
