Answer:
it's b
Explanation:
The emission spectrum which is a line spectrum of iodine consists of 6 blue lines as it absorbs yellow light.
What is emission spectrum?Emission spectrum is defined as a spectrum of a chemical compound or substance composed of frequencies of electromagnetic radiation. Radiations which are emitted while electron make transition from higher to lower energy level.
Energy of photon is equal to the difference between the two energy states . There are many possible electronic transitions in an atom and every transition has a specific wavelength.
Collection of different transitions with respect to different wavelengths makes up an emission spectrum.Emission spectrum of each element is unique and therefore spectroscopy is used to identify elements which are present in different substances.

Which one of the following statements about orbitals is INCORRECT?
1) orbitals are regions in space where one is likely to find an electron
2) orbitals can hold up to two electrons
3) orbitals can hold two electrons provided they are spinning in the same direction
4) s, p, d and f orbitals are possible
3) orbitals can hold two electrons provided they are spinning in the same direction
We define an orbital in chemistry as a region in space where there is a high probability of finding an electron.
Each orbital holds a maximum of two electrons which spin in opposite direction according to Pauli exclusion principle.
According to this principle no two electrons can have the same set of quantum numbers. As a result, the spin quantum numbers of two electrons in the same orbital must differ hence they spin in opposite directions.

what are the 3 types of bonds in chemistry? and how can you tell when a chemical has that bond?
Answer:
Ionic bonding, Covalent bonding, Metallic bonding.
» My memory
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. » Wikipedia

Astatine-210 has a half-life of 8.08 days. What fraction of a sample of astatine-210 is left unchanged after 16.16 days?
Answer:
0
Explanation:
Given parameters:
Half-life = 8.08days
Unknown:
What fraction is left unchanged after 16.16days = ?
Solution:
The half - life of a substance is the time taken for the half of a radioactive material to decay to half.
Day 0 Day 8.08 Day 16.16
100% 50% 0% Parent
0% 50% 100% Daughter
After 16.16 days, non of the original sample will remain unchanged.

What is the mole ratio of PCl3 to PCl5?
Answer: The mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1
Explanation:
According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.
[tex]PCl_3+Cl_2\rightarrow PCl_5[/tex]
Thus in the reactants, there is 1 mole of [tex]PCl_3[/tex] and 1 mole of [tex]Cl_2[/tex] molecule. And thus there is 1 mole of [tex]PCl_5[/tex] in the product as well.
Thus the mole ratio of [tex]PCl_3[/tex] to [tex]PCl_5[/tex] is 1: 1

What does the chemical formula show?
a) The number of elements in each molecule
b) The number of atoms in each molecule
c) How heavy the molecule is.
d) The elements in the molecule and the number of atoms of each one .
Answer:
A
Explanation:
You can eliminate C because you need to consult a periodic table to determine the mass (not the weight).
There are other answers you could use. The wording is awfully sloppy. D is an example of that. The elements part is true, the atoms part is not really true in all cases. For example NaCl is table salt and both the elements are ions, not atoms. Na is plus ion and Cl is minus one. B is wrong for the same reason.
I think in the end I would choose A. I think this is a very sly question. It is not really testing chemistry. It is testing how well you know your definitions.

Choose the balanced chemical equation below that best represents the following reaction:
When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl).
NaCl + H2O → NaHCO3 +CO2 + HCl
CO2 +H2O + NaCl → NaHCO3 + HCl
NaHCO3 + HCl → CO2 + H2O + NaCl
HCl + NaCl + H2O → NaHCO3 +CO2
The balanced chemical equation :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
Further explanationA balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same
When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .
This statement shows that
Reactants (located to the left of the reaction)
Baking soda (NaHCO₃) and Hydrochloric acid (HCl)
product (located to the right of the reaction)
Carbon dioxide(CO₂),water (H₂O) and Sodium chloride (NaCl).
So the reaction :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl

Calculate the number of moles in 7g of nitrogen gas
Answer:
0.2498mol[tex]N_{2}[/tex]Explanation:
7gN2 x [tex]\frac{1 mol}{2(14.01) g}[/tex]
=0.2498mol N2
Nitrogen gas has the formula [tex]N_{2}[/tex] so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).
