Answer:
0.336 J/g/C
Explanation:
Recall the equation for specific heat:
q = mcΔT
1250 = 25 x c x 149
c = 0.336
In a polar covalent bond, there is an unequal sharing of electrons between atoms. If there is equal sharing otherswise it is considered polar covalent. The answer for 1) is D. Water has a higher boiling point because of the strong attraction between polar water molecules due to hydrogen bonding. Answer for 2 is D.
Answer:
Explanation:
as we know that 1kg =1,000,000 mg
therefore
0.425 kg= 0.425*1,000,000/1=425000
result:
0.425 kg contain 425000 mg
