A science experiment calls for mixing 3 and two-thirds cups of distilled water with 1 and three-fourths cups of vinegar and Two-thirds cups of liquid detergent. How much liquid in all, in cups, is needed?

They describe different forms of matter, solid and liquid. As well as both being entirely differently structured forms of matter.

They distinguish between solid and liquid matter. In addition to being completely different types of matter.

Matter is defined as everything that takes up space other words, the "material" that makes up the universe.

All matter is composed of substances known as elements, each of which has unique chemical and physical properties and cannot be decomposed into other materials through ordinary chemical reactions.

Atoms and molecules make up some of the material in the category of solids, liquids, and gases.

The matter that makes up wood have characteristics of any solid, i.e., high intermolecular force of attraction that holds it shape.

The matter that is making water will have liquid characteristics, which do not have a particular shape and will have weak intermolecular forces of attraction.

Thus, this is the chief difference between the "matter that makes up wood" and the "matter that makes up water".

Answer:Direction? tell me if im wrong!

Explanation:

Answer:

(see below)

Explanation:

Using process of elimination:

A) lose energy

When a liquid freezes into a solid, the particles move a lot slower because the once-flowing particles are now about to be stuck in place, barely vibrating in its structure.

So, yes, they has lost energy, but there can be a better answer.

B) gain energy

When a liquid freezes into a solid, the particles move a lot slower, so there is no way there is more energy now. If there was to be more energy, it would be a gas now.

So, no, they did not gain energy.

C) move faster

When a liquid freezes into a solid, the particles move a lot slower, so there is no way they're moving faster now. Otherwise it would be a gas now.

So, no, they did not move faster.

D) disappear

Particles of a substance don't just . . . disappear. There is no way matter can be destroyed or created, only changed in form, according to the Conservation of Matter.

So, no, they did not disappear.

So the answer is most likely A.

Answer:

Explanation:

A. λ = 3 m

B. E = 1.9878 x 10⁻³³ J

C. Total energy :  1.9878 x 10⁻²⁰ J

The photoelectric effect is an electron coming out of a metal because of electromagnetic radiation

One type of electromagnetic radiation is light

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

A. wavelength

[tex]\tt \lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3.10^8}{1.10^8~Hz}=3~m[/tex]

B. energy of one photon

[tex]\tt E=h\times f\\\\E=6.626\times 10^{-34}\times 3=1.9878\times 10^{-33}~J[/tex]

C. Total energy

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{3.75 \times {10}^{21} }{6.02 \times {10}^{23} } \\ = 0.00622923...[/tex]

Answer:

See attached picture!

Explanation:

You are dealing with salts.  This means that you write the name of the metal (sodium) with the name of the nonmetal (chloride).  You need to change the end of the name of the nonmetal (chlorine to chloride; bromine to bromide).

To find the balanced compound, use the charges of the cations and anions.  You need to write the compounds so that the total charge of the salt is 0.

How to balance the oxygen atoms.

Add a coefficient of 5 to the oxygen molecule on the left side of the equation. You now have 10 oxygen atoms on each side.

C3H8 + 5O2 --> 4H2O + 3CO2.

The carbon, hydrogen, and oxygen atoms are balanced. Your equation is complete.

A=20

B=40

C=Ca

D=10

E=9

F=F

The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.

So atomic number = number of protons = number of electrons

Mass Number (A) is the sum of protons and neutrons

Mass Number (A) = Number of protons + Number of Neutrons

So that the relationship between atomic numbers and mass numbers can be formulated as follows:

Atomic Number (Z) = Mass Number (A) - Number of Neutrons

A=atomic number=number of protons=20

B=mass number=protons+neutrons=20+20=40

C=the element with atomic number 20 and mass number 40 is Ca,

[tex]\tt _{20}^{40}Ca[/tex]

D=number of neutrons=mass number-number of protons =19-9=10

E=atomic number=number of protons=9

F=the element with atomic number 9 and mass number 19 is F

[tex]\tt _9^{19}F[/tex]

Independent variable: SIZE OF NAILS

Dependent variable: NUMBER OF PAPER CLIPS

Explanation:

The independent variable in an experiment is the variable that is changed or manipulated by the experimenter in order to effect a measurable response. In this investigation, the DIFFERENT SIZES OF NAILS USED is the INDEPENDENT VARIABLE.

The dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this investigation, THE NUMBER OF PAPER CLIPS the electromagnet could pick up is the DEPENDENT VARIABLE.

The dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

Answer:

B

Explanation:

i just take the test

An ionic bond has a high melting point because a lot of energy is required to overcome the attractive forces that hold the ionic crystal together. The correct option is B.

In an ionic bond, atoms transfer electrons to form positively charged cations and negatively charged anions. These oppositely charged ions are attracted to each other, creating strong electrostatic forces between them.

When a solid ionic compound is heated, the thermal energy increases, causing the ions to vibrate more vigorously. As the temperature continues to rise, the ions gain enough energy to break free from their fixed positions within the crystal lattice. This requires a lot of energy because the attractive forces between the ions are strong and must be overcome.

Thus, the correct option is B.
