Answer:
Ethanol
Explanation:
Hello,
Since the hexanes and the ethyl acetate are mostly composed by C-C, C-H and for the ester C-O bonds which are apolar, just the ethanol which has one O-H bond could be classified as polar, allowing H-bridges to be present.
Best regards.
Answer:
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
Answer:
Density of iron shot is 7.92 g/mL.
Explanation:
Given data:
Mass of water + iron + graduated cylinder = 94.74 g
Mass of water + graduated cylinder = 66.24 g
Volume of water = 45.50 mL
Volume of water + iron shot = 49.10 mL
Density of iron = ?
Solution:
First of all we will calculate the volume of iron shot.
Volume of iron shot= (Volume of water + iron shot) - Volume of water
Volume of iron shot= 49.10 mL - 45.50 mL
Volume of iron shot= 3.6 mL
Now we will calculate the mass of iron shot.
Mass of iron shot = (Mass of water + iron + graduated cylinder ) - Mass of water + graduated cylinder
Mass of iron shot = 94.74 g - 66.24 g
Mass of iron shot = 28.5 g
Now we will calculate the density of iron shot.
d = m/v
d = 28.5 g / 3.6 mL
d = 7.92 g/mL
Density of iron shot is 7.92 g/mL.
