Answer:
0.171 grams of oxygen combined with the metal.
Explanation:
Mass of magnesium oxide produced = 0.421 g
Mass of magnesium metal used = 0.250 g
Suppose reaction completely converts the magnesium into magnesium oxide.
Mass of oxygen combined with magnesium = m
0.421 g = 0.250 g + m
m = 0.421 g - 0.250 g = 0.171 g
0.171 grams of oxygen combined with the metal.
Answer:
The rate at which the air temperature changes with height in the atmosphere surrounding a cloud or a rising parcel of air. The overall average rate is a decrease of about 6.5°C/km, but the rate varies greatly in different regions of the world, in different airstreams, and at different seasons of the year.
I will help u if u want me to
Answer:
You would use an electrolytic cell.
In a crystal, the particles are arranged in an orderly, repeating, three-dimensional pattern.
Option C
<u>Explanation:</u>
Solid crystal particles can be ions, molecules or atoms, based on the material kind. The three-dimensional solid crystal system is called the crystal lattice. The crystals are divided into general categories according to their shape.
The crystal is characterized by faces that intersect at specific angles characteristic of this material. Crystal is a material in which particles get arranged in an ordered, repeatable, three-dimensional way. Means, a solid contains an atomic patterns that is uniformly repeated in three dimensions.
