Answer:

Each energy sublevel contains a different number of electrons. For example, sublevel D can contain up to 10 electrons

Explanation:

The atoms are surrounded by propellers that within each propeller there is a certain number of electrons, these electrons jump from orbit to orbit according to the amount of energy they have. The four levels that make up the electronic cloud that surrounds an atom are: s p d f.

When these electrons change orbit or level they release energy in the form of light, which is known as a photon.

B. The moon
Tides are due to the gravitational forces of the Moon and the Sun. The tide is high when the moon or the sun or both are on the side of the sea and vice versa.
The effect of tides due to the moon is much greater than that of the sun, because the moon is much closer to the earth.

Which of the above solutions could be used to remove lead from lead (II) nitrate?
alisha [4.7K]

Ni solution could be used to remove lead from lead (II) nitrate.

Explanation:

The removal of lead from lead nitrate will take place by displacement reaction.

In displacement reaction less reactive element is displaced by more reactive element form it compound.

The reactivity is decided by the placement of metal in the activity series.

A metal which is at higher position in the activity series will be able to displace the metal or element having lower position.

From the options given we will check their position in the activity series in comparison to Pb

Cu is lower in series than Pb hence cannot displace.

Hg is placed lower in the series than Pb hence cannot displace Pb.

Ag is placed lower than Pb in the series hence cannot displace Pb.

Ni is placed above the Pb in activity series hence can displace lead.

How much 10% solution and how much 45% solution should be mixed together to make 100 gallons of 25% solution?
Gnoma [55]
       x + y = 100

0.10x + 0.45 y =25

eliminate

x + y = 100
x  + 4.5 y = 250

-3.5 y = -150
y = 42.85
x = 57.15

hope this helps

What would a pressure reading of 565 torr be in units of atmospheres?
mamaluj [8]

<u>Given:</u>

Pressure = 565 torr

<u>To determine:</u>

Corresponding pressure in atmospheres

<u>Explanation:</u>

Pressure is commonly expressed in units like:

Atmosphere (atm), Torr or mmHg

The SI unit is atm, where

760 torr = 1 atm

Thus, a pressure reading of 565 torr corresponds to:

565 torr * 1 atm/760 torr = 0.743 atm

Which correctly describes the location and charge of the electrons in an atom
Dmitry [639]
Hey there!


Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)
