When a system experiences a disturbance ( such as concentration, temperature, or pressure changes), it will respond to restore a new equilibrium state.
Answer:
A hypothesis is a statement that can be tested by scientific research. If you want to test a relationship between two or more things, you need to write hypotheses before you start your experiment or data collection.
Explanation:
From the density of ethanol given, the number of pounds of ethanol in the drum will be 46.099 pounds.
<h3>How to calculate density</h3>
Density of ethanol = 0.789/cm³
1 gallon = 3785.4ml
Volume of ethanol = 7 gallons = 7 × 3785.4ml = 26497.8ml
Mass of ethanol = Volume × Density.
= 26497.8 × 0.789
= 20906.764g
Since 1g = 0.002205 pounds, the mass of ethanol will be:
= 20906.764 × 0.002205
= 46.099 pounds.
