I think it might be D or B
And my other two might be A or C
Answer:
Understanding the unit cell of a crystalline solid will help you in determining the empirical formula of the ionic solid compound because they both represent the smallest portion of the whole crystalline solid proportion.
Explanation:
A unit cell is the smallest portion of a crystal lattice, that can show the 3 dimensional pattern of the whole crystal.A formula unit is the lowest whole number ratio of ions in a an ionic compound.By considering the smallest repeating units/ unit cell, you can describe the structure of a crystalline solid.Knowing this can help in determining the empirical formula of the ionic solid compound.
The answer for the following problem is explained below.
- <u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Explanation:
Given:
mass of methane = 6.00 × 10^-3 grams
+ 
→ 
+ 
Firstly balance the following equation:
Before balancing the equation:
→ 
After balancing the equation:
→ 
where;
represents methane molecule
represents oxygen molecule
represents carbon dioxide molecule
represents water molecule
+2 → + 2
16 grams of methane → 44 grams of carbon dioxide
6 × 10^-3 grams of methane → ?
= 
= 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.
<u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Answer:
1s22s22p63s1 is the electronic configuration of sodium.
Explanation:
B) a geographical map
Explanation:
A geographical map is an example of a model.
A model is an abstraction of the real world. It simply helps us to have a simplified view about a course we are studying.
- A map is model based on several projections and mathematical underlining principles.
- The gives an image of the 3-D world in a 2-D format usually on paper.
- The earth is a spherical body but a map shows two dimensions mostly.
- Also, a map has scale which helps to freely work with them and comprehend them more:.
