Red is the color that its related to
Answer:True
Explanation: Moment magnitude is used by the USGS- it is based on the total moment release of the earthquake. Moment is a product of the distance and the force. The moment magnitude scale gives an esitmate of the total energy released from the earthquake
Answer: What is one source of thermal energy in the interior of the Earth?
Explanation:
Answer:
Explanation:
Use the ideal gas equation:

Where:
- p is pressure: 0.950atm
- V is volume: unknown
- n is number of moles: unknown
- R is the universal constat of gases: 0.08206 atm.liter/ (K.mol)
- T is the absolute temperature: 345K
Use the <em>molar mass</em> of the gas to include the density in the formula:
- molar mass = mass in grams / number of moles
- ⇒ mass in grams = number of moles × molar mass
- density = mass in grams / volume
- ⇒ density = number of moles × molar mass / volume
- density = (n/V) × molar mass
- ⇒ n/V = density / molar mass
Clear n/V from the gas ideal equation and subsittute with density/molar mass:
- density / molar mass = n/V
- density/molar mass = p/(RT)
- molar mass = density × RT / p
Now you can subsitute the data:
molar mass = (3.50g/liter) × 0.08206 atm.liter/(K.mol) × 345K / 0.950 atm
- Round to the nearest whole number: 104g/mol ← answer
Answer is: 4.0 mol of lithium nitride would be produced.
Balanced chemical reaction: 6Li + N₂ → 2Li₃N.
n(Li) = 12 mol; amount of substance.
From chemical reaction: n(Li) : n(Li₃N) = 6 : 2 (3 : 1).
n(Li₃N) = n(Li) ÷ 3.
n(Li₃N) = 12 mol ÷ 3.
n(Li₃N) = 4 mol; amount of lithium nitride.
