Hi

only compound must two different atom.

Element have made by only single atom.
_________________________________
Compound:
A compound is formed when two or more elements chemically combine together. The elements react chemically and form chemical bonds between the atoms of the elements.

A mixture is a combination of two or more substances which are not chemically the same. ____________________________________
Homogeneous mixtures:
Homogeneous mixtures have uniform composition and appearance throughout .A homogeneous mixture is also called a true solution.
Example: sugar solution, ocean water, soft drinks, etc.
____________________________________
Heterogeneous mixtures:
Heterogeneous mixtures consist of different substances.
Examples: mixture of iron and sulphur, mixture of sand and table salt, etc.


so only elements are single atom.

all these are combination of atoms.

thanks for asking

HELP PLEASE BOYLES LAW
kogti [31]

Answer:

3 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 2 L

Initial pressure (P₁) = 0.75 atm

Final pressure (P₂) = 0.5 atm

Final volume (V₂) =?

Using the Boyle's law equation, the new volume (i.e final volume) of the Ne gas can be obtained as:

Initial volume (V₁) = 2 L

Initial pressure (P₁) = 0.75 atm

Final pressure (P₂) = 0.5 atm

Final volume (V₂) =?

P₁V₁ = P₂V₂

0.75 × 2 = 0.5 × V₂

1.5 = 0.5 × V₂

Divide both side by 0.5

V₂ = 1.5 / 0.5

V₂ = 3 L

Thus, the new volume of the Ne gas is 3 L

A wave of wavelength 0.3 m travels 900 m in 3.0 s. Calculate its frequency.
Crank

Answer: 1000 Hz

Explanation:

You can calculate frequency by dividing velocity by wavelength

Frequency = velocity/wavelength

Find velocity first.

900 m/3 s = 300 m/s

Plug values in to find frequency.

F = (300 m/s)/0.3 m

F = 1000 Hz

True or false, both mass spectrometry and infrared spectroscopy involve the interaction of molecules with electromagnetic energy
zavuch27 [327]
Yes, it is true, both mass spectrometry and infrared spectroscopy involve interaction of molecules with electromagnetic waves. ;Mass spectrometry method is used to determine the mass of a substance while infrared spectroscopy is used to determine the functional groups in molecules. Both methods involve the analysis of electromagnetic light interaction with molecules.

Two objects experienced the same displacement in the same amount of time. The two objects must have the same -
nikdorinn [45]

If two object experiences the same displacement at the same time, the two objects must have the same average velocity.

The average velocity of an object is defined as the change in displacement per change in time of motion. This can be written as follows;

avg. \ velocity = \frac{\Delta \ displacement }{\Delta \ time} \\\\V = \frac{\Delta \ x}{\Delta t}

If two object experiences the same displacement at the same time, it means that the change in displacement with time is constant.

\frac{\Delta x_1}{\Delta t_1} = \frac{\Delta x_2}{\Delta t_2} = V_{avg}

Thus, we can conclude that if two object experiences the same displacement at the same time, the two objects must have the same average velocity.

If length of wire is doubled keeping the diameter constant ,its Youngs modulus will be​
Luda [366]

Answer:

Y = Stress / Strain = (F / A) / (l / L)   where l is the change in length

Since L is doubled and A remains the same one would expect l, the change in length to also double so Y remains the same.

As an example think of hanging a weight from a spring and the same weight from a similar spring of twice the length - one would expect the longer spring to show twice the extension of the shorter spring.
