Answer: 1 mole Kr
Explanation: solution
83.80g Kr x 1mole Kr / 84 g Kr
= 0.997 or approximately 1 mole Kr
Convection is the transfer of heat/thermal enrgy by the movement of a fluid(either a liquid or gas).
The answer would be
C) To reduce destruction by providing early warning of severe weather
This can help us because then we can plan our day-to-day activities better and can definitely help keep us out of danger.
Answer:
Yes
Explanation:
Denatured ethanol fuel is a polar solvent, which is soluble in water. A
Polar solvent is a compound with a charge separation in chemical bonds, such as alcohol, most acids, or ammonia. These have affinity with water and will dissolve easily. Denatured fuel ethanol has a flash point of -5 ° F and a vapor density of 1.5, indicating that it is heavier than air.
Consequently, ethanol vapors do not rise, similar to the gasoline vapors they are looking for lower altitudes. The specific gravity of denatured fuel ethanol is 0.79, which indicates that it is lighter than water and has a self-ignition temperature of 709 ° F and a boiling point of 165-175 ° F. Like gasoline, the most denatured fuel, the greatest danger of ethanol as an engine fuel component is its flammability.
It has a wider flammable range than gasoline (LEL is 3% and UEL is 19%).
They will mold into different shapes
