Answer:
The balanced equations for the reactions are outlined below:
Explanation:
A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.
- Hydrogen sulfide gas (
) and oxygen gas (
) react to produce sulfur dioxide gas (
) and water vapor gas. - The balanced equation for the reaction, taking into consideration the states is:
→ 
Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).
The balanced equation:
→ 
Answer: The mass percent of carbon in acetylene is 92.31 %.
Explanation:
In
, there are 2 carbon atoms and 2 hydrogen atoms.
To calculate the mass percent of element in a given compound, we use the formula:

Mass of carbon = 
Mass of acetylene = 
Putting values in above equation, we get:-

Hence, the mass percent of carbon in acetylene is 92.31 %.
Answer:
choice 3
Explanation:
homeostasis is the ability of an organism to remain in balance so for two systems two show homeostasis pick the choice that shows two separate systems working together for a common goal in this case breathing.
