Answer:
n₁ = 1.0× 10⁻⁴ mol
Explanation:
Given data:
Initial volume of balloon = 230 mL
Initial number of moles of He =?
Final number of moles of He = 3.8 × 10⁻⁴ mol
Final volume of balloon = 860 mL
Solution:
The given problem will be solve through Avogadro law,
"Number of moles of gas and volume are directly proportional to each other at constant temperature and constant pressure"
Mathematical relationship:
V₁/n₁ = V₂/n₂
No we will put the values.
230 mL /n₁ = 860 mL/ 3.8 × 10⁻⁴ mol
n₁ = 230 mL× 3.8 × 10⁻⁴ mol/ 860 mL
n₁ = 874 × 10⁻⁴ mol. mL / 860 mL
n₁ = 1.0× 10⁻⁴ mol
Answer:
C. The ocean waters are heating up which leads to warmer, less dense air rising to form clouds
Explanation:
Greenhouse gases, due to their ability to trap heat, has caused an increase in the Earth's atmospheric temperature called GLOBAL WARMING. The result is that more heat is being radiated down to Earth from the sun. This could lead to hurricanes in water bodies.
Hurricanes are forceful storms that occurs when ocean waters heat up leading to warmer, less dense air that rises to form clouds. Hurricanes are called tropical cyclones.
Answer:
i is the correct answer.
Explanation:
the RAM of aluminum is indeed 27. And since the RAM of substances are measured in terms of the C-12 isotope then R indeed explains why the RAM Al is 27.
A food chain is a sequence going from the producers on the bottom to the consumers to the top that shows what consumer eats what
When an atom shares electrons they form a covalent bond.
