Answer:
There are essentially three methods used to produce ethanol:
Manufacture from ethene using steam (the "synthetic" route)
Production from sugars and starches by fermentation, using yeasts.
Production from biomass waste, using bacteria.
Please give brainlist if this helped
I would say copper, silver, and tin, since an alloy is a mixture of metals and metalloids.
Answer:
The name of the phase change is;
Sublimation.
Explanation:
CO₂(s) + energy ⇒ CO₂(g)
Sublimation is the transition of a substance from its solid state to the gaseous state without first turning to a liquid due the high rate of absorption of of thermal energy of the substance such that the substance does not melt first.
As such sublimation is the endothermic process taking place at a temperature and pressure lower than the triple point of the substance in the substance's phase diagram. The triple point is the lowest temperature and pressure at which a substance can exist as a liquid.
Answer:
The molecules in a gas have more freedom of movement than molecules in a liquid. Molecules in gas are free to move away from each other, so gas can expand to fill its container.

Answer:
Percent error = 41%
Explanation:
Percent error:
Percent error is the difference between the measured value and actual value divided by actual value multiply by 100.
Given data:
Actual length of rope = 3.15 m
Measured length of rope = 1.85 m
Percent error = ?
Solution:
Formula:
Percent error = [measured value - actual value / actual value ] × 100
Now we will put the values in formula.
Percent error = [1.85 - 3.15 / 3.15 ] × 100
Percent error = [-1.3 /3.15 ] × 100
Percent error = -0.41 × 100
Percent error = 41%
The negative sign shows that measured value is less than the actual value but often results are reported in absolute value.
