What is the difference between solvation and dissociation
Answer:
The key difference between dissociation and solvation is that dissociation is the breakdown of a substance into the atoms or ions from which the substance is made of whereas solvation is the dissolution of a substance in a solvent due to the attraction forces between solvent molecules and the components.
Explanation:
Solvation refers to the process of surrounding solute particles with solvent molecules, leading to the formation of a solution. Dissociation specifically refers to the breaking apart of ionic compounds or molecules into their constituent ions when dissolved in a solvent.
Solvation occurs due to the attractive forces between the solute and solvent molecules, such as dipole-dipole interactions or hydrogen bonding. The result of solvation is the formation of a homogeneous solution where the solute particles are evenly distributed at the molecular level within the solvent.
Ionic compounds are composed of positively charged cations and negatively charged anions held together by electrostatic forces. When an ionic compound is dissolved in a solvent, such as water, the solvent molecules interact with the compound's ions, pulling them apart and surrounding them.

A glass container was initially charged with 1.95 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as the temperature was increased to 28.1 °C, so the final pressure in the container was reduced to 0.998 atm. What quantity in moles of the gas sample are present at the end?
Answer:
45830.4 moles
Explanation:
Ideal gas law is the hypothetical equation in which the pressure, volume, and temperature of the gas are directly related. It can be denoted as:
PV = nRT
The ideal gas law is:
PV = nRT
where,
P = Pressure
V = Volume
R = Gas constant
T =Temperature
n = moles
Given:
Moles in container = 1.95
Temperture = 294.85 K
Pressure = 3.75 atm
Volume =?
Substituting the values:
V = nRT/P
V = 1.95 × 0.082 × 294 / 3.75
Volume = 12.5 L
Now, the condition when changed, such that temperature is 301.25 K, pressure is 0.998 atm, and Volume is 12.5 L, then moles will be equal to:
PV/RT = n
0.998 × 12.5 / 0.082 × 301.25 = n
n = 45830.4 moles
Therefore, 0.521 moles is still present in the container.

The percent yield obtained from the stoichiometry of the reaction when the moles of the reactants and products are known.
What is stoichiometry?Stochiometry gives the relationship between the mass and mole or moles and volume in a reaction.
Q1)
K2PtCl4 + 2NH3 ----> Pt(NH3)2Cl2 +2KCl
Number of moles of NH3 = 34.5 g/17 g/mol = 2.03 moles
2 moles of NH3 yields 2 moles of KCl
2.03 moles of NH3 yields 2.03 moles of KCl
Theoretical yield of KCl = 2.03 moles * 75 g/mol = 154 g
Again,
2moles of NH3 yields 1 mole of Pt(NH3)2Cl2
2.03 moles of NH3 yields 2.03 moles * 1/2 = 1.015 moles
Mass of Pt(NH3)2Cl2 = 1.015 moles * 301 g/mol = 306 g
% yield = 76.4 g/306 g * 100/1 = 25%
Q2)
H3PO4 + 3 KOH ------> K3PO4 + 3 H2O
Number of moles of H3PO4 = 49.0 g/98 g/mol = 0.5 moles
If mole of H3PO4 yield 1 mole of K3PO4
0.5 moles of H3PO4 yield 0.5 moles of K3PO4
Mass of K3PO4 = 212 g/mol * 0.5 moles = 106 g
Percent yield = 49.0 g/106 g * 100 = 46%
Q3)
Al2(SO3)3 + 6 NaOH ------> 3 Na2SO3 + 2 Al(OH)3
Number of moles of Al2(SO3)3 = 389.4 g/294 g/mol = 1.32 moles
If 1 mole of Al2(SO3)3 yields 3 moles of Na2SO3
1.32 moles of Al2(SO3)3 yields 1.32 moles * 3 moles/1 mole = 3.96 moles
Mass of Na2SO3 = 3.96 moles * 126 g/mol = 498.96 g
Percent yield = 212.4 g/498.96 g * 100/1 = 43%
Q4)
Al(OH)3(s) + 3 HCl(aq) -------> AlCl3(aq) + 3 H2O(l)
Number of moles of Al(OH)3 = 50.3 g/78 g/mol = 0.64 moles
If 1 mole of Al(OH)3 yields 1 mole of AlCl3
0.64 moles of Al(OH)3 yields 0.64 moles of AlCl3
Mass of AlCl3 = 133 g/mol * 0.64 moles = 85 g
Percent yield = 39.5 g/85 g * 100 = 46%
Q5) K2CO3 + 2HCl --------> H2O + CO2 + 2KCl
Number of moles of K2CO3 = 34.5 g/138 g/mol = 0.25 moles
1 mole of K2CO3 produces 2 moles of KCl
0.25 moles of K2CO3 produces 0.25 moles * 2 moles/1 mole = 0.5 moles
Mass of KCl = 0.5 moles * 75 g/mol = 37.5 g
If 1 mole of K2CO3 yields 1 mole of H2O
0.25 moles of K2CO3 yields 0.25 moles of H2O

Explain the process of photosynthesis. Make sure to give the inputs and outputs.
help im failing science
Answer:
Photosynthesis is the process by which carbon dioxide and water are converted into oxygen and glucose. The plant consumes glucose as food, and oxygen is produced as a by-product. During cellular respiration, oxygen and glucose are converted to water and carbon dioxide. Water and carbon dioxide are by-products of the process, while ATP is the energy that is transformed. Water, carbon dioxide, and energy in the form of sunshine are all inputs in photosynthesis, and the outputs are glucose and oxygen.
Answer:
photosynthesis takes carbon dioxide from our atmosphere and turns it into oxygen. A plant requires sunlight, water, and carbon dioxide to make both sugar and oxygen. . Input: For photosynthesis to take place, water from the roots, carbon dioxide from the air, and energy from the sunlight are needed. Output: Photosynthesis creates glucose (sugar) used for/stored as food and releases oxygen into the air.
