Answer:
m = 50.74 kg
Explanation:
We have,
Initial temperature of water is 20 degrees Celsius
Final temperature of water is 46.6 degrees Celsius
Heat absorbed is 5650 J
It is required to find the mass of the sample. The heat absorbed is given by the formula ad follows :
c is specific heat of water, c = 4.186 J/g°C
So,
So, the mass of the sample is 50.74 kg.
The drawing is correct because there are 12 atoms of each type on each side of the arrow.
Answer: 25g/ml
Explanation:
Density = 100.0g/ 4.0mL = 25g/mL
A phospholipid has a charged head and an uncharged tail.
It is false that 1 mole of nacl(s) has a greater entropy than 1 mole of nacl (aq).
this is because nacl(aq) is in aqueous state while nacl(s) is in solid state. Nacl(aq) has greater entropy than nacl(s) because in
aqueous state their is increase in entropy. the entropy of the two ions in water has greater entropy than the solid nacl.
