Answer:
Less than
Explanation:
The process of dissolution occurs as a kind of "tug of war". On one side are the solute-solute and solvent-solvent interaction forces, while on the other side are the solute-solvent forces.
Only when the solute-solvent forces are strong enough to overcome the pre-mixing forces do they overcome the "tug of war", and thus dissolution occurs.
Thus, it is concluded that the interaction forces between solute particles and solvent particles before they are combined are less than the interaction forces after dissolution.
For the dissolution of the soluteparticles in the solvent particles, the force of attraction between the particles of solute and between the particle of solvent must be less than the interaction between the solute particles and solvent particles after dissolution.
In a solution the forces act between the solute molecules, solvent molecules, and solute-solvent molecules. For the dissociation to take place the bond between the solute and solvent has to be formed. The resultant will result in the dissolution of the solute in the solvent mixture. The strong solute-solute and solvent-solvent bond will result in difficulty in the formation of the solute-solvent bond, and the dissolution will not take place.
Thus for the dissolution of the solute particles in the solvent particles, the force of attraction between the particles of solute and between the particle of solvent must be less than the interaction between the solute particles and solvent particles after dissolution.

Answer:
Label
Explanation:
You need to search if the chemical need a glass or plastic container. Also if the chemical need to be in a clear or dark container that can protect it from light. Also if need to be a certain temperature, for example, if need to be in the fridge or can be at room temperature.
Most important is that you need to label with the name, formula, date, and if you have the number of lot and the expiration date.
Answer:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.

There are 929 grams in 1.11 moles of manganese sulfate.
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
Step1: Calculate the molar mass of
3(54.94) + 7(32.07) + 28(16) = 837.31g
Step2: Calculate the mass of
Thus, the mass of 1.11 moles of is 929 grams.

Step 1: Find the molar mass of Mn3(SO4)7.
Mn3(SO4)7 = 3(54.94) + 7(32.07) + 28(16) = 837.31g
Step 2: Calculate grams of Mn3(SO4)7 in the following manner:
1.11 mol Mn3(SO4)7 (837.31g Mn3(SO4)7 /1 mol Mn3(SO4)7 ) = 929g Mn3(SO4)7
Answer:
Explanation:
Sn + 2HBr = SnBr₂ + H₂
Here HBr is an acid but Sn is not a base . It is a metal . So it is not an acid - base reaction .
HCl + KOH = KCl + H₂O
HCl is an acid and KOH is a base so it is an acid base reaction.
2AlCl₃ + 3Ca(OH)₂ = 2Al(OH)₃ + 3CaCl₂
It is an acid base reaction . It is so because aluminium hydroxide is a lewis acid and calcium hydroxide is a base . So it is an acid base reaction .
2C₂H₆ +7O₂ = 4CO₂ + 6H₂O
It is not an acid base reaction . It is actually an example of oxidation reaction in which ethane burns in oxygen to give carbon dioxide and water.
