Answer:

We could say that it is the planet Neptune

Explanation:

Neptune a gaseous planet. It is the planet furthest from the Sun being at an approximate distance of 4,500 million kilometers, its mass is 1,0241 x 10^26 kg. Neptune is composed of ice and rock, with a heavy and solid core similar to Earth's. It does not have a solid surface. It is a dense planet and its magnetic field is 27 times stronger than Earth's. Neptune has an atmosphere of 74% hydrogen, 25% helium and 1% methane.

Balance the following chemical equation I would give anyone the brainiest for answering.

serg [7]

Answer :

Part 13:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3$

Part 14:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3$

Part 15:

The balanced chemical reaction will be:

$Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which an individual element of an atom present on reactant side must be equal to product side.

Draw the mechanism of polymerization of propylene with benzoyl peroxide. Show chemical structures and arrows and remember that r

allochka39001 [22]

Answer:

See explanation below

Explanation:

This mechanism of polimerization is of one type. This mechanism goes through free radical polimerization, which means that we use a initiator as the radical source, then, the polimerization begins with the breaking of the covalent bonds of that initiator. In this case the benzoyl peroxide. And this mechanism is given in three steps.

In the picture you have the mechanism in the 3 steps:

How to find how many electrons are in an element

Murljashka [212]

Explanation:

1) Locate the atomic number in the upper left corner of the square. The atomic number will tell you the number of protons

2) In a neutral state, the element will contain the same number of protons as it will electrons.

--> Boron (B) has an atomic number of 5, so it has 5 protons.

--> Having 5 protons (+1 charge each) means to be balanced, it must have 5 electrons (-1 charge each)

However, what if it's not in a neutral state?

If it's not in a neutral state, it will look something like this:

Ca ^ 2+

Btw, the "^" means that it will be written like it's an exponent. That confuses people sometimes.

Anyways, the "2+" means it's an ion with a positive charge of 2. For us to have a positive charge, it means it's lost two electrons (cause electrons are negative, so taking them away means we are left with a more positive charge).

To get the number of remaining electrons, subtract the 2 from the atomic mass. In this case, that would be 20.

20 - 2 = 18 electrons

Another example:

N ^3-

Atomic Number: 7

7 + 3 = 10 electrons.

Why did I add here instead of subtracting? It's cause the 3- means we have added electrons, resulting in the ion having a negative charge. It's got more electrons than usual.

Hopefully this helps a bit.
