Answer:
Benzene
Explanation:
You have to find the freezing point for each of these (make sure they're in Celsius). You might want to double check these but:
Benzene: 5.5
Water: 0
Butane: -138
Nitrogen: -210
Answer:
79 g
Explanation:
Density (d) of iron = 7.9 g/cm³
Volume of the iron (V) = 10 cm³
Mass of the iron (m) = ?
Solution:
Formula will be used
d = m/V
As we have to find mass so rearrange the above equation
m = dV . . . . . . . . . . . (1)
Put values in above equation 1
m = 7.9 g/cm³ x 10cm³
m = 79 g
So,
mass of iron = 79 g
The best explanation, though it's controversial, is that a great flood had once covered the earth for a brief period of time.
Acids change the rate Corrosion and increase its temperature.
