Answer: 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Explanation:
1) Chemical equation:
Formaldehyde + oxgyen → CO₂ + H₂O
H₂CO + O₂ → CO₂ + H₂O
2) That equation is already balanced
3) Mole ratios
1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O
4) Then, every mol of mol of H₂CO produces 1 mol of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Answer:
It's A., thats conduction and its a heat transfer
Explanation:
Answer:
1.33 Å
Explanation:
Given that the edge length , a of the KCl which forms the FCC lattice = 6.28 Å
Also,
For the FCC lattice in which the anion-cation contact along the cell edge , the ratio of the radius of the cation to that of anion is 0.731.
Thus,
.................1
Also, the sum of the radius of the cation and the anion in FCC is equal to half of the edge length.
Thus,
...................2
Given that:
To find,
Using 1 and 2 , we get:
<u>Size of the potassium ion = 1.33 Å</u>
It should be A for number 36
Answer:
Compare Silicon and Sulfur on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Silicon vs Sulfur with most reliable information about their properties, attributes, facts, uses etc. You can compare Si vs S on more than 90 properties like electronegativity , oxidation state, atomic shells, orbital structure, Electronaffinity, physical states, electrical conductivity and many more.
