Answer:
Lithium (Li)
Explanation:
Lithium has an atomic number of 3
Answer:
Ionic compounds, such as sodium chloride, are also highly soluble in water. Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
Explanation:
Hey there!
In order to solve for the percentage of water in the compound, you will first need to find its total molar mass. You can do this by adding up the molar masses of each individual element in the compound. Then, you will divide the mass that you find of the water molecules by the total mass to get the percentage.
→ Na₂CO₃ ×<span> 10 H</span>₂<span>O
</span>→ Na₂ = 22.9898 × 2 = 45.9796
→ C = 12.0107
→ O₃ = 15.999 × 3 = 47.997
→ 10 H₂O = 18.015 × 10 = 180.15
Now, just add all of those numbers up for the total molar mass.
→ 45.9796 + 12.0107 + 47.997 + 180.15 = <span>286.1373
</span>
The last step is to divide the molar mass of the 10 water molecules by the total mass.
→ 180.15 ÷ 286.1373 = <span>0.62959 </span>≈ 0.63
Your answer will be about 63%.
Hope this helped you out! :-)
The interior of mars is rigid
Explanation:
To produce the magnetic field of the earth, the outer core is fluid and constantly moving.
- The outer core is made up of metals
- These metals are rich in iron and nickel and some other elements.
- During the early formation of the earth, these minerals differentiated into this layer of the earth based on their density.
- But the outer core region is molten and fluid.
- The movement of these materials is responsible for the production of the geo-magnetic field that makes the earth behave like a bar magnet.
Mars has no magnetic field and we can suggest that its interior is rigid and solid.
