Answer:
Greater
Greater
Explanation:
The amplitude of a wave is the height of the wave or the vertical displacement of the wave motion. We determine a wave amplitude usually by looking at the graph of the wave.
Amplitude is directly proportional to the energy of a wave. The higher the amplitude of a wave, the more its energy.
Frequency is the number of waves that passes a point at a particular instance of time. It is also directly proportional to the energy carried by a wave. The higher the frequency of a wave, the greater its energy.

In your own words, please explain how to name acids.
Answers
Answer:
Acids are named based on their anion — the ion attached to the hydrogen. In simple binary acids, one ion is attached to hydrogen. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them.

A wave is a _____that transfers _____ through a ______
A.) medium, disturbance, energy
B.) disturbance, energy, medium
C.) energy, disturbance, medium
D.)disturbance, medium, energy
Answers
A wave is a disturbance that transfers energy through a medium. There
are types of such as sound and light waves.
A wave involves the transfer of energy such as sound, light waves etc
through a medium. The medium could be through liquids , solids or air and
they have characteristic waves which pass through them.
When a wave transfers energy through a medium, the matter involved
doesn't experience any type of movement.

Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
An atom is made up of three fundamental subatomic particles. Protons are the positively charged particles Electrons are the negatively charged particles Neutrons do not carry any charges.When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.

Which models of the atom does the experimental evidence from Bohr's hydrogen experiment support? Explain why these models are compatible with the experimental results.
The models are Daltons, Thompsons, and Rutherfords
Answers
Answer:
Rutherfords
Explanation:
The model of the atom supported by Bohr's hydrogen experiment is the Rutherford's model of the atom.
Rutherford through his experiment on gold foil suggested the atomic model of the atom. The model posits that an atom has a small positively charged center(nucleus) where nearly all the mass is concentrated.
Surrounding the nucleus is the large space containing electrons. In the Bohr's model of the atom, he suggested that the extranuclear space of the atom is made up of electrons in specific spherical orbits around the nucleus.SOMEONE HELP ME PLEASE ILL GIVE BRAINLY!

Answers
Answer:
[OH⁻] = 8.91x10⁻¹²M
Explanation:
In aqueous solutions, the [OH] and [H⁺] are associated in the equation of hydrolisis of water:
1x10⁻¹⁴ = [OH⁻] [H⁺]
With pH, we can solve for [H⁺] and obtain, the [OH⁻] using this equation:
pH = -log [H⁺]
[H⁺]= 10^-pH
[H⁺] = 1.122x10⁻³M
1x10⁻¹⁴ = [OH⁻] [1.122x10⁻³M]
[OH⁻] = 8.91x10⁻¹²MHow did the substance oxygen change the world??

How many moles of NaCl could be found in 0.4 L of a 0.9 M solution? Round your answer to
two decimal places.
Answers
Answer:
0.36mol
Explanation:
Given parameters:
Volume of NaCl = 0.4L
Molarity = 0.9M
Unknown:
Number of moles = ?
Solution:
To find the number of moles, the molarity of a solution is the amount of solute contained in a solution.
Molarity = [tex]\frac{number of moles}{volume}[/tex]
Number of moles = molarity x volume
Insert the parameters and solve;
Number of moles = 0.4 x 0.9 = 0.36mol

The correct option is D. Volume. The other properties do not change with increasing or decreasing amount of the mineral
Under a certain set of conditions, the percent yield of a reaction that produces carbon dioxide is 75.0%. What mass in grams of CO2 will actually be recovered if the theoretical yield is 26.7 grams?
Answers
Answer:
Actual yield = 20.03g
Explanation:
[tex]% yield = 100.\frac{actual yield}{theoretical yield}[/tex]% [tex]yield[/tex] = [tex]100. \frac{actual \ yield}{theoretical \ yield}[/tex]
Actual yield = % yield.(theoretical yield) / 100
Actual yield = 75.26.7/100
Actual yield = 20.025
Answer: I got 20.025 and then I rounded it to 20.0

How much heat is required to raise the temperature of a 6.21 g sample of iron from 25.0 oC to 79.8 oC?
Answers
Answer:
151.1J
Explanation:
Given parameters:
Mass of iron = 6.21g
Initial temperature of iron = 25°C
Final temperature of iron = 79.8°C
Unknown:
Amount of heat = ?
Solution:
The amount of heat require to cause this temperature can be determined using the expression below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
Specific heat capacity of iron 0.444J/g°C
Insert the parameters and solve;
H = 6.21 x 0.444 x (79.8 - 25)
H = 151.1J

Contrast and compare:
a) ionic and covalent bonding
Answers
Answer:
Ionic bonds - an intramolecular force exist in a nonmetal and metal compounds such as NaCl. The Na donate 1 electon to Cl to complete its octet rule.
Covalent bond - an intramolecular force exist in a nonmetal and nonmetal compounds such as bonds O2, Cl2, CO2, sugar, proteins and most of organic compounds and biomolecules by sharing electrons to bond.
There are two types of covalent bonds: polar and nonpolar. Polar bond is a bond between two different nonmetal atoms of different electronegativities. While nonpolar bond is a bond between the same atom or two differenct atoms of the same electronegativities (if there is). Their electronegativities pull will cancel so that their overall polarity is zero.
