Explanation:
The diagram below shows the distance traveled by two light waves in 1 second.
Based on the diagram, which of these conclusions is correct?
The frequency of Wave 1 is double the frequency of Wave 2.
The frequency of Wave 2 is double the frequency of Wave 1.
The wavelength of Wave 1 is four times the wavelength of Wave 2.
The wavelength of Wave 2 is four times the wavelength of Wave 1.
Please help
Answer:
The frequency of Wave 2 is double the frequency of Wave 1.
Explanation:
Waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.
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.

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.

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.

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).
what are most of the needed formulas to find the molar volume and the molar concentration (Cm) 11th grade chemistry
Answer:
Explanation:
molar volume=moles*given volume
for molar concentration we use two formulas molarity and molality
molarity=no of moles/volume
molality=no of moles/kilogram

с . It is the most powerful explanation scientists have to offer at this time.
Explanation:
The current atomic theory can best be described as the most powerful explanation scientists have to offer at this time.
Using this explanation, scientists can make technological innovations based on the theory.
As a theory and with more researches, the theory can be improved further with time. The theory no doubt might be changed in the future if more research evidence supports an alternate view.In what way do the atoms in the same row of the Periodic Table increase from left to right?
Answer:
As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.

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
