Answer:
Number of Na ions in 14.5 g of NaCl is 1.49 × 10²³.
Number of Cl ions in 14.5 g of NaCl is 1.49 × 10²³.
Total number of ions = 1.49 × 10²³ + 1.49 × 10²³ = 2.98 × 10²³.
Explanation:
1 mole of any compound contains 6.023 × 10²³ molecules.
molecular weight of NaCl is 23 + 35.5 = 58.5 g.
so, 58.5 grams of NaCl makes 1 mole
⇒ 14.5 g of NaCl = 
= 0.248 moles.
⇒ 0.248 mole contains 0.248 × 6.023×10²³ molecules
= 1.49 × 10²³ molecules.
And 1 molecule contains 1 Na ion and 1 Cl ion.
⇒ number of Na ions in 14.5 g of NaCl is 1.49 × 10²³.
⇒ number of Cl ions in 14.5 g of NaCl is 1.49 × 10²³.
Total number of ions = 1.49 × 10²³ + 1.49 × 10²³ = 2.98 × 10²³.
Answer:
mass and height of the object.
This is the full question: what is the strongest intermolecular force in a liquid containing molecules with nonpolar bonds?
A. Covalent Bonds
B. Dispersion Forces
C. Hydrogen Bonds
D. none of these
This is the answer: B. Dispersion forces
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
Explanation:
It is known that the specific heat capacity of Liver 
is 3.59 kJ 
It is given that :
Initial temperature of Liver = Body temperature = 
= 310 K
Final temperature of Liver = 180 K
Relation between heat energy, mass, and change in temperature is as follows.
Q = 
Now, putting the given values into the above formula as follows.
Q =
Q = 
= 700.05 kJ
Therefore, we can conclude that amount of heat which must be removed from the liver is 700.05 kJ.
