Answer:
A. 1.50 M
Explanation:
Concentration is the number of moles of solute dissolved in a volume of 1 L of solution
Mass of LiBr - 97.7 g
Number of moles of LiBr - 97.7 g /87 g/mol = 1.12 mol
Equation for concentration is as follows
Concentration = number of moles / volume of solution in L
Substituting the values
Concentration = 1.12 mol / 0.7500 L
Concentration of LiBr is 1.50 mol/L
Hello!
Similarities:
-They can conduct electric current because they both are ionic substances.-
-They both form Water and Salt when neutralized.
Differences:
-Acids release Hydronium ions (H₃O⁺) when hydrolyzed while Bases release Hydroxyl ions (OH⁻) when hydrolyzed.
-Acids are commonly formed with non-metals (such as Chlorine, Sulfur, Oxygen, and Nitrogen) while Bases are commonly formed with metals (such as Sodium, Potassium, Calcium, and Copper).
Have a nice day!
Iodine hexafluoride is the chemical name
Answer:
1dm = 10cm
1dm3 = 10cm x 10cm x 10cm = 1000cm3
1L = 1000cm3
so 1litre = 1dm3
4 moles in 2 dm3
= 2 moles in 1dm3 = 2moles in 1L = 2M
1L = 1000cm
0.3 moles in 200cm3 =
200cm3 = 0.2L
so 0.3 moles in 0.2 L = 1.5 moles in 1 L = 1.5M
(I have tried to simplify and show why 1dm3 = 1L)
I hope this helps you understand!
Answer: It is chemical energy, which is a type of potential energy.
Explanation: Natural gas consists of mixture of hydrocarbons such as methane, butane and others which are chemical substances, thus they contain chemical energy stored in the bonds of the molecules.
Potential energy is any form of energy that has stored potential that can be used later. Examples include nuclear energy, chemical energy, etc.
Thus the type of energy present in natural gas is chemical energy, which is a type of potential energy.
