There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively.
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
The name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively. Magnesium fluoride is an ionic compound.
Therefore, the name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively.

Answer: The amount of energy required to raise the temperature is 13323.75 joules.
Explanation :
The amount of energy required to raise the temperature can be calculated as follows.
where,
q = heat energy
m = mass of water
C = specific heat
T = temperature
Remember that the specific heat of water is .
Therefore, putting the values in the above equation as follows.
= 13323.75 joules
So, the amount of energy required to raise the temperature is 13323.75 joules.

Answer: The mass of given number of molecules of aspirin is 0.359 grams.
Explanation:
We are given:
Number of molecules of aspirin =
We know that:
Molar mass of aspirin = 180.16 g/mol
According to mole concept:
number of molecules are contained in 1 mole of a compound
Also, number of molecules of aspirin has a mass of 180.16 grams
So, number of molecules will have a mass of
Hence, the mass of given number of molecules of aspirin is 0.359 grams.
The mass in grams of 1.20 x10^21 molecules of asprin is 0.359 grams
calculation
find the number of moles of aspirin by use of Avogadro's law that is 1 mole =6.02 x10^23 molecules
what of 1 .20 x10^21 molecules
= (1 mole x 1.20 x10 ^21 molecules)/6.02 x10^23 molecules)= 1.993 x10^-3 moles
mass of aspirin= moles x molar mass
molar mass of aspirin = (12 x9)+(1 x8) +(16x4)=180 g/mol
mass= 1.993 x10^-3 moles x180 g/mol = 0.359 grams
Explanation:
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. ... Colloidal systems can occur in any of the three key states of matter gas, liquid or solid. However, a colloidal solution usually refers to a liquid concoction.
Answer:
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid.
