Based on location in the periodic table, which element has chemical properties that are most similar to iodine
xenon (Xe)
calcium (Ca)
Selenium (Se)
fluorine (F)
Answer:fluorine
Explanation:
Based on location in the periodic table, fluorine (F) has chemical properties that are most similar to iodine.
In the periodic table, elements are classified in groups and periods. The elements in the same group are chemically similar and they have the same number of valence electrons. Elements in the same period have the same highest energy level.
Hence, when looking for an element that is most chemically similar to iodine, we have to consider the element that is in the same group with iodine.
Both fluorine are iodine are both in group 17 hence, fluorine is most chemically similar to iodine.

at 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. what is the mass % of ammonium chloride in the solution? the formula weight of nh4cl is 53.50 g/ml.
At 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. The mass percent of the ammonium chloride in the solution is 2.003%.
The number of moles of a substance can be estimated as:
[tex]\mathbf{number\ of\ moles = \dfrac{mass}{molar \ mass}}[/tex]
Given that:
number of moles = 0.376 Mmolar mass of ammonium chloride = 53.50 g/mlMass = number of moles × molar mass
Mass = 0.376 × 53.50
Mass = 20.116 grams
In one mL of ammonium chloride; the grams of ammonium chloride is:
[tex]\mathbf{= \dfrac{20.116 \ grams}{1000 \ mL}}[/tex]
= 0.020116 g/mL
The mass of ammonium chloride in the solution can be computed as:
[tex]\mathbf{=(\dfrac{mass \ of \ NH_4Cl}{density \ of \ the \ solution})\times 100}[/tex]
[tex]\mathbf{=(\dfrac{0.020116 }{1.0045})\times 100}[/tex]
= 2.003%
Therefore, we can conclude that the mass percent of the ammonium chloride in the solution is 2.003%.

a space probe identifies a new element in a sample collected from an asteroid. successive ionization energies, in attojoules per atom, for the new element are given in the table. i1 i2 i3 i4 i5 i6 i7 0.507 1.017 4.108 5.074 6.147 7.903 8.294 to what family of the periodic table does this new element probably belong?
The element belongs to group 17 of the periodic table.
In the periodic table, elements are arranged in groups depending on their properties. Usually, elements whose atoms have the same number of valence electrons are placed in the same group.
All the elements in group 17 have seven electrons on their outermost shell. Since an ionization energies of the electrons on the valence shell of an atom are always close together, the ionization energies of the seven electrons as shown indicate that they must be on the same shell.
Hence, the new element must be a member of group 17 of the periodic table.

Elements have different properties because they are made up of different types of
atoms.
Right a 5 sentence paragraph explaining this!!!
Answer:
,
Explanation:
Answer:
An atom is the smallest partical in the universe that makes up everything you see around you. Every chemical element is also made up of atoms. Since atoms are what give each element their defining characteristics, each element can be composed of multiple atoms but you must have all of the same type of atoms combined in order for it to be considered an element. For example the element gold can only contain gold atoms. If you mix the atoms of one element with the atoms of another your substance has then been changed from an element to a compound.

Explanation:
Which property accounts for the fact that atoms can be identified by an examination
of the emission spectrum?
A. Each kind of atom has a different mass number.
B.Each kind of atom has a different atomic number.
C.Each kind of atom has a different isotopes.
D. Each kind of atom has a characteristic difference in energy levels for electrons.
Answer:
Explanation:
D is the answer
Each kind of atom has a characteristic difference in energy levels for electrons, this property accounts for the fact that atoms can be identified by an examination, therefore the correct answer is option D.
What is the photoelectric effect?It is the process of emission of electrons from the material because of absorption of electromagnetic radiation in form of photons of light waves.
The photoelectric effect explains the particle behavior of the light waves.
Each kind of atom has a characteristic difference in energy levels for electrons this fact can be used to identify the different atoms by using inspection.
Thus, the correct answer is option D.

during the process of nuclear decay what form of energy is released?
Answer:
Mostly Kinetic
Explanation:
electronegativities of the elements be, mg, ca, and sr follow a specific trend within their group. based on this trend, the atoms of which element will have the least attraction for an electron?
Based on the trend of electronegativities values of the elements Be, Mg, Ca, and, Sr within their group (increasing from bottom to top), the atoms of the element Sr will have the least attraction for an electron.
We need to remember that electronegativity indicates the affinity or attraction of an element for an electron. Hence, the higher the electronegativity, the higher the attraction of that element for an electron.
The values of electronegativities of the given elements are the following:
Be = 1.57
Mg = 1.31
Ca = 1.0
Sr = 0.95
We can see that the increasing trend of electronegativities in this group is from the bottom to the top, having the Sr with the lowest electronegativity value and the Be with the highest.
This trend is related to atomic size, the larger the atomic size, the lower the electronegativity because the electron in the outermost shell will feel less attraction towards the nucleus of an atom. In a group of the periodic table, the size of an atom will increase from top to bottom.
Therefore, according to the said above, the atoms of the Sr will have the least attraction for an electron (it has the lower electronegativity value).

2. How many atoms of hydrogen do you have in the reactants? How many atoms of hydrogen to you have in the product?
3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?
1. No, it doesn't.
2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.
3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.
But on balancing the eqn,
CH4 + 2O2 > CO2 + 2H2O
The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.

why does the reaction of anthracene with maleic anhydride needs to be kept away from water?
Answer:
Water separates the two reactants into two layers, stopping the reaction.
Explanation:
Maleic anhydride can and will react with water.
The reaction between maleic anhydride and anthracene is a Diels Alder reaction. This type of reaction is a cycloaddition reaction.
What is Diels Alder reaction?The Diels Alder reaction is a member of a class of reactions called cycloadditions. This reaction involves three pi bonds, two from the diene and one from the dienophile in a concerted reaction to give a six-membered ring.
Since this reaction involves four pi electrons in the diene and two pi electrons from the dienophile, it is sometimes referred to as a 4+2 cycloaddition.
The presence of electron donating groups on the diene and the electron withdrawing groups on the dienophile favors normal Diels Alder reactions. The reaction involves the formation of new σ bonds which are energetically more stable than π bonds.
Anthracene can react with water, breaking the center ring. Maleic anhydride can react with water, opening its ring. The reactants get seperated into two layers by water and thereby stops the reaction.
