Answer:
C. 0.35cm
Explanation:
The length indicated by the arrow along the ruler should recorded be recorded as "0.35cm".
This is correct because when counting the measurement on the ruler, the first line on the ruler is 0.1cm, the second line is 0.2cm, and so on. The spaces between each line is 0.05cm. So, the arrow is pointing on the space between 0.3cm and 0.4cm.
Therefore, 0.3cm + 0.05cm = 0.35cm.(answer).
The empirical formula : Fe₂O₃
<h3>Further explanation</h3>
Given
34.97g of Iron
15.03g of Oxygen
Required
The empirical formula
Solution
Mol ratio :
Fe(Iron) : 34.97 g : 56 g/mol = 0.624
O(Oxygen) : 15.03 g : 16 g/mol = 0.939
Divide by 0.624 :
Fe : O = 1 : 1.5
Fe : O = 2 : 3
Answer:Observable properties are characteristics or things about materials or objects that we can describe using our five senses. Color, texture, hardness, and flexibility are all things we can determine with our senses.
Explanation:
Answer:l ectrons will occupy a p orbital only after the s orbital is full
Explanation: Electrons can begin to occupy energy levels with the next highest integer designation only after all of the orbitals on the energy level below it are occupied.
