You are currently in a stable orbit 9000 km (1km=1000m) from the center of planet Proxima Centauri B.

Molecules have ionization energies, just like atoms do. The ionization energy for molecular oxygen, for example, is 1314 kJ/mol.

taurus [48]

Answer:

91.1835 nm

Explanation:

Given that the ionization energy of the oxygen molecule = 1314 kJ/mol

It means that

1 mole of oxygen molecules can be ionized by the energy = 1314 kJ = 1314000 J

1 mole of molecules contains 6.022 × 10²³ atoms

So,

6.022 × 10²³ atoms of oxygen molecules can be ionized by the energy = 1314000 J

1 atom require $\frac{1314000}{6.022\times 10^{23}}\ J$ of energy

Energy = $2.18\times 10^{-18}\ J$

Also

$E=\frac {h\times c}{\lambda}$

Where,

h is Plank's constant having value $6.626\times 10^{-34}\ Js$

c is the speed of light having value $3\times 10^8\ m/s$

$\lambda$ is the wavelength

So,

$\lambda=\frac {h\times c}{E}$

$\lambda=\frac{6.626\times 10^{-34}\times 3\times 10^8}{2.18\times 10^{-18}}\ m$

$\lambda=91.1835\times 10^{-9}}\ m$

Also,

$1\ nm=10^{-9}}\ m$

So, wavelength = 91.1835 nm

Relate the number of protons in the nucleus of an atom to the properties of matter.

Sauron [17]

Answer:

The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element

Thermohaline currents are influenced by wind.<br><br> True or false?

tresset_1 [31]

Answer:

FALSE

Explanation:

The under-water deep ocean currents that are generated due to the differences in the water density are generally termed as the thermohaline circulation. It is mainly controlled by the two factors namely the temperature and the salinity. The word 'thermohaline' is directly derived from the temperature (thermo) and salinity (haline).

This thermohaline circulation is considered as the oceanic conveyor belt that allows the water to move under the surface of water at certain depths from the equator to the poles and back from the poles to the equator.

Thus, it is directly associated with the density of the water. It has no relation with the wind.

Hence, the above statement is False.

Using the Br?nsted-Lowry concept of acids and bases, identify the Br?nsted-Lowry acid and base in each of the following reaction

antiseptic1488 [7]

Answer:

$H_2PO_3^-$ is Bronsted Lowry base.

$H_2O$ is Bronsted Lowry acid.

Explanation:

According to the Bronsted Lowry conjugate acid-base theory:

An acid is defined as a substance which donates protons and form conjugate base
A base is defined as a substance which accepts protons and forms conjugate acid.

$H_2PO_3^-(aq)+H2O(l)\rightarrow H_3PO_3(aq)+OH^-(aq)$

$H_2PO_3^-$ is Bronsted Lowry base.It accepts protons and forms conjugate acid $H_3PO_3$

$H_2O$ is Bronsted Lowry acid.It donates protons and forms conjugate base $OH^-$

$(CH_3)_2NH(g)+BF_3(g)\rightarrow (CH_3)_2NHBF_3(s)$

There in no exchange of proton in an above reaction.Neither of the reactants and products are Bronsted Lowry acid or Bronsted Lowry base
