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.
The ratios which are needed to determine the mass of oxygen produced from the decomposition of 10 grams of potassium chlorate are;
- 31.998 g O2 : 1 mole O2
- 3 mole O2 : 2 mole KClO3
- 112.55 g KClO31 mole KClO3
From stoichiometry;
- We can conclude that according to the reaction;
3 moles of oxygen requires 2 moles of KClO3 to be produced.
And from molar mass analysis;
- 31.998 g O2 is equivalent to 1 mole O2
- O2112.55 g KClO3 is equivalent to 1 mole KClO3
