Answer:
A. To study the chemical composition of the surface of a planet
Explanation:
Strictly speaking, a spectrometer is any instrument used to view and analyze a range (or a spectrum) of a given characteristic for a substance (for example, a range of mass-to-charge values as in mass spectrometry), or a range of wavelengths as in absorption spectrometry like nuclear magnetic radiation spectroscopy

Answer:
ExplanationImage
Atmospheric Pressure is the force per unit area exerted on a surface due to the weight of air molecules above it. It is caused by the collisions of the air molecules with that surface.:
Answer:
B: circulatory system
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Answer:
a. Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
b. C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
c. 3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
Explanation:
<em>a. The formation reaction of Ca(NO₃)₂(s) is:</em>
Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
- 1.0 mole of solid Ca reacts with 1.0 mole of N₂ gas and 3.0 moles of O₂ gas to produce 1.0 mole of solid Ca(NO₃)₂.
<em>b. The formation reaction of CH₃OH(l) is:</em>
C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
- 1.0 mole of solid C (graphite) reacts with 2.0 mole of H₂ gas and 0.5 mole of O₂ gas to produce 1.0 mole of liquid CH₃OH.
<em>c. The formation reaction of NaClO₄(s) is:</em>
3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
- 3.0 moles of solid NaCl react with 4.0 moles of O₂ gas to produce 3.0 moles of solid NaClO₄.
