We will use this formula:
M1C1ΔT1 = M2C2ΔT2
when M1 mass of sample 1 = 31 g
C1 for water = 4.184
and ΔT1 = (Tf- 290)
and M2 of sample 2 = 47 g
C2 for water = 4.184
and ΔT2 = (340 - Tf)
so by substitution, we can get Tf (the final temperature):
31 g * 4.184 * ( Tf - 290 k ) = 47g * 4.184 * (340 - Tf)
∴Tf ( the final temperature) = 320 K
3n of force North. Since the 12 cancel the other 12 out.
Those are basically molecular formula. Which is Table sugar or cane sugar. Generally called sucrose.
Answer:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
