Answer:

Conserving water can help alleviate the effects of water shortages in any given community. Water use drains other resources. Using in-house water resources requires energy to deliver the water to your home. This energy-use increases when you use hot water since a lot of energy goes into heating.

An isotope of potassium with a half-life of roughly one billion years is often used in radioactive dating. This isotope decays t

Archy [21]

Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.

Explanation :

Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.

$_Z^A\textrm{X}+_{-1}^0\textrm{e}\rightarrow _{Z-1}^A\textrm{Y}$

The equation for the given reaction is,

$_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}$

Thus, the chemical symbol for the element that results from this process is, argon (Ar).

To three significant digit,what is the mass percentage of iron in the compound Fe2O3

svlad2 [7]

69.9%

Explanation:

To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.

Mass percentage = $\frac{molar mass of Fe}{Molar mass of Fe_{2}O_{3} }$ x 100

Molar mass of Fe = 55.85g/mol

Molar mass of O = 16g/mol

Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7‬g/mol

Mass percentage = $\frac{2(55.85)}{159.7} x 100$ = 69.94% = 69.9%
