Answer:
False
Explanation:
Ocean waves are something you can physically see whereas Gamma Rays and Light Waves are something on the Electromagnetic Spectrum.
The statement is false because a solution, which consists of two or more substances, is also uniform throughout. An example is sugar in water.
a. K
d. Ci
b. Ca
c. S e. Ba f. Br
Answer:
The ion is written in the attached file
Explanation:
The most typical ions formed by K, Ca, and S are K+, Ca2+, and S2-, respectively.
The symbol of the ion most typically formed by each of the elements can be determined by looking at their positions on the periodic table and considering their electron configuration.

hydroxide ion concentration is decreased.
[H+] is decreased.
[OH-] is decreased.
Answer:
[H+] is decreased.
Explanation:
Arrhenius Theory:
An acid is a substance which produces one or more hydrogen ions, (H+) in aqueous solution.
Examples:
A Base is a substance which produces one or more hydroxyl ion or hydroxide ion (OH-) in aqueous solution.
Examples
Please note:
(aq) stands for aqueous which means in the presence of water that is, water acts as a solvent
So, on adding a base to the water increase in will take place and this will decrease the Hydrogen ion concentration
Pure water contains
if the solution is acidic
if the solution is Basic
Answer:
C
Explanation:
The first and most obvious statement is that [OH-] is increased, but that is not offered to you.
The second most obvious statement is that the [H+] ion is decreased. That is offered to you. It is C

The observations are as follows: Initially with the plates in the dark, no electrons pass between the plates and no current flows. As we shine light on the plates, going from low energy red to high energy blue, suddenly current begins to flow. How?
Einstein explained the result be describing the light waves as packets of energy. He called the packets of energy photons. Each photon has a specific energy, the shorter the wavelength, the higher the energy. When a high-energy photon hits the plate (such as a green or blue), the photon has enough energy to knock out an electron and then the electron, being negative, will fly to the positive side. At this point, current flows.
The lower energy photons are unable to know out the electrons and no energy can flow.
The exciting thing to note is the treatment of energy as a particle or a packet, it is consistent with the fact energies are not additive. If we can bump electrons with light at 600 tera-hertz , we can�t just use 300 tera-hertz for twice the time and still expect to bump electrons.
What if the photon has greater than the threshold energy required to pop out an electron? The extra energy just goes into the kinetic energy of the electron. This relationship can be described by the following equation.
hf = w + KE
where hf is the energy of the photon.
w is the energy required to bump an electron.
KE is the kinetic energy of the electron.
If the photon has less energy than w, no electron is emitted.
Increasing the brightness of light for red, yellow, orange, and green colors can cause a metal to absorb more energy and potentially undergo physical or chemical changes such as expansion or emitting light of a certain color.
Increasing the brightness of the light for the colors red, yellow, orange, and green will affect the metal in different ways depending on the specific metal being used. Generally, metals will absorb some of the energy from the light and convert it into heat. This increase in heat can cause the metal to expand, change its color, or undergo other physical or chemical changes.
For example, when a metal is exposed to bright light, it may heat up and expand, leading to changes in its shape or dimensions. Additionally, depending on the metal and its properties, the increased brightness of light can lead to certain metals absorbing specific wavelengths of light, which can cause the metal to emit photons and exhibit a characteristic color.
In summary, increasing the brightness of light for red, yellow, orange, and green colors can cause a metal to absorb more energy and potentially undergo physical or chemical changes such as expansion or emitting light of a certain color.

Suppose you use 0.0150 liter of a 2.50 M solution of silver nitrate. Assuming the reaction goes to completion, how much silver sulfide is produced? Use the periodic table.
A. 1.49 g
B. 4.65 g
C. 9.30 g
D. 18.6 g
Answer:- B. 4.65 g.
Solution:- The given balanced equation is:
It asks to calculate the mass of silver sulfide formed by when 0.0150 liters of 2.50 M of silver nitrate are used.
Moles of silver nitrate are calculated on multiplying it's liters by its molarity and then on multiplying by mol ratio, the moles of silver sulfide are calculated. These moles are multiplied by the molar mass to convert to the grams.
Molar mass of = 2(107.87)+32.06 = 247.8 g per mol
The dimensional set up for the complete problem is:
=
So, the correct choice is B. 4.65 g.
Answer:
that jawn gon be 4.65 g
