Answer:
3.6cm^3
Explanation:
v=m/d
v=46.1/12.8
v=3.6cm^3
Answer: In order to a solute to dissolve in a solvent, both the attraction forces that bind the units of solute together and the intermolecular forces that bind the molecules of solvent together must be weaker than the attraction forces between the particles of solute and the molecules of solvent.
Explanation:
The solute particles in are binded together in virtue of attractive forces (the nature and strength of these forces depends on the particular solute).
The same happens with the solvent molecules: they are binded by attractive forces (similarly, the nature and strength of these forces depend on the particular solvent).
To get dissolved (form solution) the particles of solute must be separated and mixed with the solvent particles in a process called solvatation.
The solute particles must surrounded by the solvent particles.
When the forces of attraction between the solute particles and the solvent are stronger than the forces of attraction that bind the solute particles, the solute particles move away from the solid solute and are integrated into the solution.

The balanced equation is: 2Fe + 3F2 ⇒ 2FeF3
A chemical equation needs to be balanced if you want to make the wide variety of the atoms of the reactants equal to the variety of the atoms of the goods.
Given,
Iron + fluorine ⇒ Iron Flouride
Fe + F2 ⇒ FeF3
Now to balance this reaction:
2Fe + 3F2 ⇒ 2FeF3
This reaction is balanced.
This medicine is a mixture manufactured from nutrients, iron, and fluoride. it's miles utilized in infants and youngsters to deal with or prevent deficiency because of terrible weight loss programs or low tiers of fluoride in drinking water and other sources.

Answer:
iron+flourine.............iron flouride
Fe+F2.............FeF3
the above reaction is not balanced
now to balance this reaction
2Fe+3F2...........2FeF3
now this reaction is balanced
Use Newton’s Law to explain why a bowling ball will slow down and stop when rolled in a flat surface, like a street.
Answer:
Force is must to change the velocity of an object. Force is always equal to the mass of the object times its acceleration.
Explanation:
From the second law of Newton, it states that the force is the product of mass of an object and its acceleration. Here, when the bowling ball is rolling across a flat surface, frictional force acts on it which oppose the motion of the ball and causes deceleration of the ball. This is an example of rolling friction. Acceleration of the bowling ball depends directly to the force of friction and indirectly to its mass.
To find the number of atoms in 4.0 Mol of sodium, you need to multiply the number of moles by Avogadro's number. This will give you approximately 2.4088 x 10^24 atoms.
To calculate the number of atoms in 4.0 Mol of sodium, you need to use Avogadro's number, which is 6.022 x 1023 atoms per mole. The calculation is as follows:
Start with the number of moles given, which is 4.0 mol.Multiply this by Avogadro's number (6.022 x 1023) to get the total number of atoms:4.0 mol x 6.022 x 1023 atoms/mol = 2.4088 x 1024 atoms
So, there would be approximately 2.4088 x 1024 atoms in 4.0 mol of sodium.

Answer is: hydroxyl group (-OH).
A functional group is a group of atoms that determines many of the properties of an organic molecule.
Functional group for alcohol is hydroxyl group or hydroxy group (-OH).
In organic chemistry, alcohol and carboxylic acids contain hydroxy groups.
The atoms of functional groups are linked to each other and to the rest of the molecule with covalent bonds.
