The image, blanks and options are missing in the question. So the image is attached below and the complete question is:
Describe the celestial object in the image.
The object is called________ a because it is producing _______ and has not yet ________ .
First Blank: A.Meteor B.Meteorite C.Meteoroid
Second Blank: A. a streak of light B. An orange Horizon C. A star- Filled sky
Third Blank: A. Reached earths atmosphere B. Struck Earth C. Completed an orbit
Answer:
First Blank - A. Meteor
Second Blank - A. a streak of light
Third Blank - A. Reached earths atmosphere
Explanation:
The given image shows celestial object called meteor.
The meteor is often called shooting star as it produces a streak of light. When a meteoroid reaches Earth's atmosphere, it experiences a friction which allows the meteoroid to burn up and produce a streak of light in the sky.
Hence, the correct answer for blanks is Meteor, a streak of light and Reached earths atmosphere.
Answer:
The molar amount of gas.
Explanation:
According to the ideal gas law,
PV = nRT
P = pressure of gas
V = volume of gas
n = number of moles of gas
R = ideal gas constant
T= temperature of gas
When pressure, volume and temperature of gas is known the molar amount of gas can be determine by using above formula.
For example:
P = 1.2 atm
R = 0.0821 atm. L.mol⁻¹ .k⁻¹
T = 293 K
V = 2 L
n = ?
Solution:
PV = nRT
1.2 atm × 2L= n × 0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K
n = 1.2 atm × 2L / 0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K
n = 0.1 mol
