Answer: i think its d
Explanation:
D. The scientist provides unbiased information to the government.
When we describe properties of substances, we can divide them into chemical properties and physical properties. Chemical properties are how the substance react with other substances, while physical properties are mostly observable or measurable, which does not require the substance into reacting with other substances.
Since group I are all metals, the physical properties include shiny, malleable, ductile, good conductors of heat and electricity, have high melting points etc.
Chemical properties include react vigorously with water to form metal hydroxide and hydrogen, or react with oxygen to form metal oxide.
Answer:
Not much heat moves into the lower levels of the ground. The heat that the ocean absorbs is mixed with the lower water quickly. ... At night, while the land cools off quickly, the water at the surface is kept warmer because the water is mixed around with the warmer water underneath.
Answer:
The answer to your question is P2 = 170.9 torr
Explanation:
Data
Volume 1 = 12.1 l Volume 2 = 21.1 l
Temperature 1 = 241 °K Temperature 2 = 298°K
Pressure 1 = 546 torr Pressure 2 = ?
Process
To solve this problem use the combined gas law.
P1V1/T1 = P2V2/T2
-Solve for P2
P2 = T1V1T2 / T1V2
-Substitution
P2 = (241 x 12.1 x 298) / (241 x 21.1)
-Simplification
P2 = 868997.8 / 5085.1
-Result
P2 = 170.9 torr
