Answer:
C. H:C:H:H
Explanation:
Follow these simple steps to correctly draw a Lewis dot structure: Add up the total number of valence electrons found in the entire compound. Draw the simple structure (skeleton structure) of the compound by connecting everything with single bonds only. Add electrons to all the noncentral atoms. Put any unused electrons on the central atom.
Answer:
Is this an actual question that you had for school?
Explanation:
Answer: Formation of hydrogen iodide will occur.
Explanation:
When molecule of hydrogen gas
and molecule of iodine gas
collide with proper orientation and with sufficient amount of energy. This collision of the two different molecules of gases will result in the formation of hydrogen iodide.
The balanced chemical equation of the reaction will written as:

Answer:
SnCrO4
Explanation:
Tin has a charge of 2+
Chromate has a charge of 2-,
therefor, the formula is equal.
