Answer:
The mass of iron piece = 586.84
Explanation:
Given,
Heat absorbed by iron piece(Q) = 5575 Joules.
specific heat capacity(Cp) = 0.95 J/g°C.
initial temperature(T₁) = 20.0°C
Final temperature(T₂) = 30.0°C
Mass of iron piece(m) = ?
The mass of iron piece can be calculated by using the formula
,
Q = (mass) (ΔT) (Cp)
Here, ΔT = T₂ - T₁ = 30°C - 20°C = 10°C
Substituting values we get,
5575 = (m)(10)(0.95)
Solving, we get,
m = 586.84 grams.
Therefore, mass of iron piece = 586.84 grams.
The possible number and location of all subatomic are one of them is electrically neutral, while the other has a stable electronic configuration.
<h3>What are subatomic particles?</h3>
Subatomic particles are those particles that are present inside the atoms. They are electron, neutron, and proton. They are charged particles, protons are positively charged, electrons are negatively charged and neutrons are neutral.
The protons and electrons totally contribute to the atomic mass of the elements.
Thus, the subatomic particles are electrically neutral and stable to electronic configurations.

Answer:
100 grams of C-14 decays to 25 grams in 11,460 years.
The C-14 isotope is only useful for dating fossils up to about 50,000 years old
If an ancient bone contains 6.25% of its original carbon, then the bone must be 22,920 years old.
Explanation:
We already know that the half life of C-14 is 5,730 years. After the first half life, we have 50 grams remaining. This takes 5,730 years. After the second half life (11,460 years now gone) we have 25 grams of C-14 left.
If a fossil material is older than 50,000 years an undetectable amount of 14C is left in the sample hence Carbon-14 is no longer suitable for dating the sample.
From;
0.693/5730 = 2.303/t log (No/0.0625No)
Where;
t = time taken and No = initial amount of C-14
0.693/5730= 2.77/t
t = 22,920 years
Noble gases having col:18
so the valence shell is D.8
