How would you prepare 2.5 L of a 0.800M solution of KNO3?

Answers

First  find the mass of solute:

Molar mass KNO₃ = 101.1032 g/mol

mass =  Molarity * molar mass * volume

mass = 0.800 * 101.1032 * 2.5

mass = 202.2064 g of KNO₃

To prepare 2.5 L (0800 M) of KNO3 solution, must weigh 202.2064 g of salt, dissolve in a Beker, transfer with the help of a funnel of transfer to a volumetric flask, complete with water up to the mark, capping the balloon and finally shake the solution to mix.

Consider the reaction below.HCIO3 + NH3 → NH4+ + CIO3-
Which is a base-conjugate acid pair?
NH3 and CIO3-
NH3 and NH4+
HCIO3 and NH3
HCIO3 and NH4+

Answers

The example of base-conjugate acid pair is B. NH3 and NH4+.

What is a base-conjugate acid pair?

A base-conjugate acid pair simply means a pair that consist of two substances that only differ by the presence of a proton (H+).

In this case, the example of base-conjugate acid pair is NH3 and NH4+ because bNH4+ is the conjugate acid of the base NH3.

Nuclear Forcesin determining nuclear binding energy, what is Einstein's equation used to do?A)convert energy to mass
B)convert joules per nucleus to joules per mole of nuclei
C)convert mass to tons
D)convert mass to energy

Answers

Answer:

D

Explanation:

Einstein's equation E = m * c2, allows to determine the energy.

How to determine nuclear binding energy? To achieve it, the mass of the nucleons it is combined and transformed into energy, at the end of the process there is less mass in the system than there was before combining and converting into energy.

Which of the following an inorganic compound?CH3(CH2)3CH3 pentane
C6H12O6 glucose
C4H10 butane
H2O water molecule

Answers

An organic compound is one which consists of a chain of carbon atoms with other atoms bonded to the chain.

Pentane has 5 carbon atoms with surrounding hydrogens.
glucose is a chain of 6 carbon atoms
butane is similar to pentane

water has no carbon atoms, and the central atom is oxygen ---> therefore it is inorganic!

The crystal lattice structure of ionic compounds is responsible for which set of characteristic properties?

Answers

Answer:

The characteristic properties are hard and brittle solids having high melting and boiling point

Explanation:

Ionic compounds are the type of chemical compounds that are formed by ionic bonding. An ionic compound is composed of two oppositely charged ions that are held together by electrostatic forces of attraction.

They are solids at room temperature and usually have a crystalline structure and have high melting and boiling point. Ionic compounds are hard but also brittle.
