Answers
Answer:
Number of moles = 1.57 mol
Explanation:
Given data:
Mass of propanol = 94.1 g
Molar mass of propanol = 60.1 g/mol
Number of moles of propanol = ?
Solution:
Formula:
Number of moles = mass/molar mass
by putting values,
Number of moles = 94.1 g/ 60.1 g/mol
Number of moles = 1.57 mol

5x10-6 mol Na2C2O4 bileşiğinde kaç tane O atomu vardır?
How many oxygen atoms are present in 5x10-6 mol Na2C2O4 ?
Answers
There are 1.204 x 10¹⁹ atoms O
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
1 mol of molecule Na₂C₂O₄ :
There are 4 mol of O in 1 mol of molecule Na₂C₂O₄
So for 5 x 10⁻⁶ mol Na₂C₂O₄ :
[tex]\tt mol~O=4\times 5.10^{-6}=2.10^{-5}[/tex]
1 mole = 6.02.10²³ particles , so number of atoms O :
[tex]\tt 2\times 10^{-5}\times 6.02\times 10^{23}=1.204\times 10^{19}[/tex]

all of the following are properties of ionic compounds except:
A. Ionic compounds have low melting points,
B. Ionic compounds have high boiling points
C. Ionic compounds conduct electricity when dissolved in water
D. Ionic compounds are solid at room temperature
Answers
Answer:
A
Explanation:
They have generally high melting point compared to covalent compounds because they are formed by electrostatic force of attraction between two opposite charge is not easy to melt them in low melting point.
Ionic compounds have high melting and boiling points. Therefore, option A is not a property of ionic compound. Hence, option A is the correct answer.
Ionic compounds are neutral compounds. Ionic compounds are formed from cations and anions. Positively charged ion (cation) and negatively charged ion (anion) are held together with strong ionic bond. Some main properties of ionic compounds are,
High melting point and boiling pointsHave definite size and shapeConduct electricity in molten statesoluble in water and not soluble in organic solventsThus, we can conclude ionic compounds have high melting and boiling points. Hence, option A is the correct answer.
