Answer:
I think beaker three will take longer to boil since there is more water present,compared to the other beakers
<span>Suda karıştırıldıysa, kaynatma ile hacmi azaltmayı deneyebilirsiniz, ancak bir veya daha fazla çözüm bulunmaması durumunda çok uzun sürecektir. Çözeltiye fazla aseton ilavesi, filtrelenebilen tuzu çöktürmelidir. Asetondan buharlaşma şeker üretecektir.</span>
<u>Answer:</u> The number of carbon and oxygen atoms in the given amount of carbon dioxide is 
and 
respectively
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of carbon dioxide gas = 3.45 g
Molar mass of carbon dioxide gas = 44 g/mol
Putting values in above equation, we get:
1 mole of carbon dioxide gas contains 1 mole of carbon and 2 moles of oxygen atoms.
According to mole concept:
1 mole of a compound contains 
number of molecules
So, 0.0784 moles of carbon dioxide gas will contain 
number of carbon atoms and 
number of oxygen atoms
Hence, the number of carbon and oxygen atoms in the given amount of carbon dioxide is and respectively
Answer:
d. its effective nuclear charge is lower than the other noble gases.
Explanation:
Xenon belongs to group O on the periodic table. Most of the elements here are unreactive.
Due to the large size of Xenon, the outermost electrons have very low effective nuclear charge. Effective nuclear charge is the effect of the positive charges of the nucleus on the electrons in orbits. This effect decreases outward as atomic shell increases.
Xenon has a very large atomic radius and there is weak a nuclear charge on the outermost electrons. The more electronegative elements would be able to attract some of its outermost electrons easily and form chemical bonds with xenon much more readily.
