The nucleus is made of protons and neutrons. It has a positive charge.
Answer:
The correct answer is C ions from the solute molecules have a strong attraction to the polar solvent molecules.
Explanation:
NaCl or Sodium chloride is an ionic compound which easily get dissolved in polar molecular compound such as water(H2O).
Both NaCl and H2O are polar compound because the atoms that forms NaCl and H2O have vast difference in their electronegativities.As a result the bonding electrons in both NaCl and H2O are not equally shared.
NaCl get dissolved in water molecules by dipole dipole interaction.
<u>Answer:</u> The density of liquid is 
<u>Explanation:</u>
We are given:
Mass of cylinder, 
= 65.1 g
Mass of liquid and cylinder combined, M = 120.5 g
Mass of liquid, 
= 
To calculate density of a substance, we use the equation:
We are given:
Mass of liquid = 55.4 g
Volume of liquid = 49.3 mL = 
(Conversion factor: 
)
Putting values in above equation, we get:
Hence, the density of liquid is
Answer for your question is;
2,6 = 8
The first shell is 2 electrons the other shell is 6 electrons
Answer:
1.23x10^-6 mole
Explanation:
A clear understanding of Avogadro's hypothesis proved that 1mole of any substance contains 6.02x10^23 atoms. This indicates that 1mole of Ag contains 6.02x10^23 atoms.
Now, 1f 1mole of Ag contains 6.02x10^23 atoms, then Xmol of Ag will contain 7.41x10^17 atoms i.e
Xmol of Ag = 7.41x10^17/6.02x10^23 = 1.23x10^-6 mole
