If not, solid.
Answer:
The answer to your question is No
Explanation:
Ionic bonding is a kind of bonding that involves the attraction between oppositely charged ions. That means that one element must have a positive charge and the other a negative charge.
Also, the difference in electronegativity of both elements must be higher than 1.7.
Both Sodium and Aluminum are positively charged then an ionic bond is not possible to be formed.
Difference of electronegativity = 1.61 (Al) - 0.93(Na)
= 0.63
To form an ionic bond the difference of electronegativity must be higher than 1.7.
Neutrons for example isotopes
Answer:
0.605 molal
Explanation:
molality is the amount of solute in a particular mass of solvent.
lets calculate the amount of benzene solute.
mass of benzene= 13.3g
molar mass of C6H6= 12*6 +1*6 =72+7=78g/mol
amount of benzene= mass/molar mass
=13.3/78
=0.1705mol
molality= amount of solute/mass of solvent in kg
mass of solvent=282g=0.282kg
molality = 0.1705/0.282
=0.605 molal
Answer: Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass, occupies 22.4 L at STP contains avogadro's number 
of particles.
Molecular mass of protein = 480,000 g/mol
Thus 1 mole of protein weighs = 480,000 g
So 27 moles of protein weighs = 
Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
