Answer : The number of atoms $Co,P,O,Na\text{ and }Cl$ are, 6, 4, 16, 6, 6

Explanation :

The given balanced chemical reaction is:

$2Na_3PO_4(aq)+2CoCl_2(aq)\rightarrow 2Co_3(PO_4)_2(s)+6NaCl(aq)$

This reaction is balanced reaction because in this reaction all the atoms of individual elements are completely balanced.

From the balanced reaction we conclude that $Co_3(PO_4)_2$ and $NaCl$ are present on the right side of the equation.

Number of atoms of cobalt (Co) present on right-side of the equation = 6

Number of atoms of phosphorous (P) present on right side of the equation = 4

Number of atoms of oxygen (O) present on right side of the equation = 16

Number of atoms of sodium (Na) present on right side of the equation = 6

Number of atoms of chlorine (Cl) present on right side of the equation = 6

Hence, the number of atoms $Co,P,O,Na\text{ and }Cl$ are, 6, 4, 16, 6, 6

6 atoms of Cobalt.

4 atoms to Phosphate (PO4).

6 atoms to sodium.

6 atoms to Chlorine.

The coefficient is one factor that tells you how many atoms go to each atom/element, however, the subscript also influences this.

If the compound has parenthesis, then the subscript within the parenthesis remains untouched and does not affect the atoms.

Basically, to calculate the atoms is multiply the coefficient (number in front of the atom) by the subscript attached to the atom. If it's a compound such as Co3PO4, then make sure the coefficient affects the second atom as well.

Hope this helps!

copper hydroxide and potassium sulfate are produced when potassium hydroxide reacts with copper sulfate balanced equation

a_sh-v [17]

This problem is requiring the balanced chemical equation that takes place when copper hydroxide and potassium sulfate are produced when reacting potassium hydroxide with copper sulfate.

<h3>Balancing chemical equations:</h3>

In chemistry, balancing chemical equations is based on the law of conservation of mass, which demands us to have equal number of atoms on both sides of the chemical equation. This can be accomplished by inserting coefficients in front of the chemical species.

For this particular case, we have potassium hydroxide with copper sulfate on the reactants side, however, copper can be copper (I) or copper (II) as it has 1+ and 2+ as its possible oxidation numbers. In addition, copper hydroxide and potassium sulfate as the products. Hence, we can assume this is all about copper (II) so we can write:

$KOH+CuSO_4\rightarrow K_2SO_4+Cu(OH)_2$

As we can see, potassium, hydrogen and oxygen have two atoms each on the products side, but just one on the reactants side; drawback we can overcome by putting a 2 in front of KOH so as to balance it:

$2KOH+CuSO_4\rightarrow K_2SO_4+Cu(OH)_2$

Identify the NMR term that corresponds to each description.

balandron [24]

Answer:

A- upfield

B- down field

C- splitting

D- chemical shift

E- integration

Explanation:

NMR is a spectroscopic technique commonly used to observe the magnetic fields around the nucleus of atoms in a compound under investigation.

A chemical shift is the difference in parts per million (ppm) between the resonance frequency of the observed protons in the compound under study and that of the tetramethylsilane (TMS) (the reference compound in NMR with a chemical shift of zero ppm because all protons in the compound are equivalent).

If signals appear close to the reference signal, the signals are said to appear upfield. If the signals appear far away from the reference, they are said to appear down field.

The presence of protons cause splitting of peaks to the magnitude of n+1. n is the number of neighboring protons. Splitting refers to the appearance of multiple peaks for a single nucleus due to neighboring nuclei.

The area of a signal that corresponds to the number of nuclei at that frequency is called the integration.

How were the elements in the first periodic table arranged?

Snezhnost [94]

Based on atomic mass

Explanation:

Elements were arranged on the first periodic table based on their atomic masses.

The mass of an atom is made up of the mass of the nucleus which contains the protons and neutrons.

Dimitri Mendeleev was the first person credited for arranging elements periodically.
He was said to have been inspired while playing his game of solitaire on a train.
On his table, he left spaces for the atomic masses of elements not yet discovered.
Today, the periodic table is based on the atomic numbers of elements. This is the number of protons in an atom.
