What are the ionic bonds

zhuklara [117]

Explanation:

Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.

This bond type is an interatomic bond.
It forms when two specie with a large electronegative difference between them combines.
This is usually a metal and a non-metal.
The metal loses its valence electrons and becomes positively charged.
The non-metal gains the electron and becomes negatively charged.
An electrostatic attraction between the two specie leads to the formation of an ionic bond.
They are solids with a high melting point.
They are soluble in polar solvents.

What is the atomic nucleus made of ?

oksian1 [2.3K]

Answer: nucleons

Explanation:

The nucleons are the particles that constitue the nuclei of the atoms. Those are protons and neutrons.

They are not elementary particles (quarks are the elementary particles that form both protons and neutrons).

Protons are the particles that define the elements. Any different elements have different number of protons. H has one proton, He has 2 protons, Li has three protons, Na has 11 protons, U has 92 protons.

Protons are positively charged and the number of protons in any neutral atom is equal to the number of electrons (the electrons, which are elementary negatively charged particles, are around the nucleous).

Neutrons have not charge and are responsible for the stability of the nuclei. They are fundamental to avoid that the repulsion forces between the positively charged protons ends causing the collapse of the nuclei.

General formulas used in decay:

$\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}$

T = duration of decay

t 1/2 = half-life

N₀ = the number of initial radioactive atoms

Nt = the number of radioactive atoms left after decaying during T time

<h3 />

No=8 mg

t1/2=60 s

T=3 min=180 s

$\tt Nt=No\dfrac{1}{2}^{T/t1/2}\\\\Nt=8.5\dfrac{1}{2}^{180/60}\\\\Nt=8.5(\dfrac{1}{2})^3\\\\Nt=1.0625~mg$

Arterial blood contains about 0.25 g of oxygen per liter at 37°C and standard atmospheric pressure. Under these conditions, the

Olin [163]

Firstly we need to determine the partial pressure of O2:

$\begin{gathered} P_{O_2}=X\times P_T \\ P_{O_2}:partial\text{ }pressure \\ X:mole\text{ }fraction \\ P_T:total\text{ }pressure \\ \\ P_{O_2}=0.209\times0.35\text{ }atm \\ P_{O_2}=0.073\text{ }atm \end{gathered}$

We will now use the Henry's Law equation to determine the solubility of the gas:

$\begin{gathered} c=K_H\times P_{O_2} \\ c:solubility\text{ }or\text{ }concentration\text{ }of\text{ }the\text{ }gas(M) \\ K_H:Henry^{\prime}sLawconstant=3.7\times10^{-2}M\text{ }atm^{-1} \\ P_{O_2}:partial\text{ }pressure\text{ }of\text{ }the\text{ }gas=0.073atm \\ \\ c=3.7\times10^{-2}M\text{ }atm^{-1}\times0.073 \\ c=2.7\times10^{-3}M \end{gathered}$

Answer: Solubility is 2.7x10^-3 M
