A wave is a disturbance that carries energy from one place to another. Matter is NOT carried with the wave! A wave can move through matter (a medium). If it must have a medium, it is called a mechanical wave.

Objects take on______ when they are lifted against the force of gravity to a position where they have the potential to fall.

Papessa [141]

A. because you haven't released the object so therefor the potential gravity force applied becomes actual when released.

The electron configuration of a neutral atom is 1s22s22p63s2. Write a complete set of quantum numbers for each of the electrons.

Pavlova-9 [17]

Answer:

The four quantum number for each electron will be:

$1s^{2}$

$n=1;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

$2s^{2}$

$n=2;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

$2p^{6}$

$n=1;l=1;\\m=+1,0.-1 \\s=+\frac{1}{2}/-\frac{1}{2}$

$3s^{2}$

$n=3;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

Explanation:

As the element is neutral, the number of protons will be equal to number of electrons which will be the atomic number of the element.

Number of electrons =12

Atomic number = 12

Element : Magnesium

The principal shell is represented by "n"

i) For "s" subshell the value of l =0 (azimuthal quantum number) thus m (magnetic quantum number)= 0

The two electrons in s subshell will have either plus half or minus half spin quantum number

ii) for "p" subshell the value for l =1

thus m = 0 or +1 or -1

The two electrons in each orbital will have either plus half or minus half spin quantum number

What problems might there be if oxygen was very soluble in water?

e-lub [12.9K]

There is a lot of water on earth. If oxygen was very soluble in water, the oceans would absorb and hold the oxygen of the atmosphere and there would be none left for plants and animals.

Hope this help you!!

Which statement about the gas laws is correct?

Elena-2011 [213]

Answer:

Gay-Lussac's law states that pressure and temperature are directly proportional

Explanation:

Gay-Lussac's law states that pressure and temperature are directly proportional. This always occurs if the volume keeps in constant.

n and V are not directly proportional, they are the same.

At Charles Gay Lussac's law

V1 = V2

n1 = n2

T1 < T2

P1 < P2

P1 / T1 = P2 / T2

If the pressure is contant:

V1 / T1 = V2 /T2
