Marianna [84]4 years ago

Answer:

  • <em>Pressure has the greatest effect on the solubility of</em> <u><em>gases</em></u>

Explanation:

Henry's law states that the solutiblity of a gas in a liquid is propotional to the pressure that the gas exertes over the liquid.

Call Sg the solubility molar concentraion of tghe gas, mole concentration of the gas, Kh the constant of proportionality, and Pg the pressure of the gas, then:

  • Sg = Pg × Kh

Then, if the pressure increases the solubility of the gas (its concentration in the liquid) increases, and if the pressure decreases the solubility of the gas decreases.

The physical reason for the influence of the pressure on the solubility  is that more pressure forces the contact between the gas over the liquid and the liquid making that more gas gets into the liquid.

write a correct and complete nuclear equation for the alpha decay of a parent atom having 102 protons and 167 neutrons useing th
scZoUnD [109]
Alpha partical is a He nucleus. When decaying alpha particle mass is reduced by 4 and atomic number is reduced by 2.

The actual element which has 102 protons is No (Nobelium). 
Since it has 167 neutrons, the mass = protons + neutrons = 102 + 167 = 269

after an alpha decay, the new element formed has 100 protons which is Fm ( Fermium)

the alpha decaying equation is,

    ₁₀₂²⁶⁹No → ₁₀₀²⁶⁵Fm + ₂⁴α + heat

the total mass and the atomic number( numbe rof protons) must be equal in both sides.

Which reactions performed in the experiment involved chemical changes?
Anvisha [2.4K]
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.

Which statement supports the claim that the continental crust was once joined together as one supercontinent, Pangaea?
Liula [17]

Answer:

each continent shifts 2-5 inches per year so once it was joined then it is what it is now.In a million years again it will comes closer and wjo knows what will happen.moutains will be formed as the tectonic plates will collide.

Write an equation that shows the formation of a sodium ion from a neutral sodium atom.
Korolek [52]

Answer:

The answer to your question is given below.

Explanation:

Sodium (Na) is a group 1 element because it has 1 electron in it's outermost shell.

Sodium ion (Na+) is formed when sodium atom (Na) lose it's outermost electron to attain the octet configuration of the noble gas element.

This can further be seen from the equation given below:

Na —> Na+ + e

Thus, we can represent the above in electronic configuration form as follow:

Na (11) => 1s² 2s²2p⁶ 3s¹

Na+ (10) => 1s² 2s²2p⁶
