Question

question 8 1 pts what is the chemical name for v2o5? question 9 1 pts recognizing how heavy main group metals ionize, what are the chemical formulas for the stable oxides of indium, in? note that chemical formulas are case sensitive. enter the formulas without subscripts (e.g., v2s5 would be given as v2s5). give the formula with the fewest number of oxygen atoms first. question 10 1 pts write the chemical formula for the binary ionic compound that will form when calcium and phosphorous react. note that chemical formulas are case sensitive. enter the formulas without subscripts (e.g., v2s5 would be given as v2s5).

Explanation:

Step1: Identify vanadium's oxidation states and naming rules

Vanadium ($V$) in $V_2O_5$ has an oxidation state of +5. Oxygen has an oxidation state of - 2. The compound is named using the stock - naming system for transition metal compounds. The name is vanadium(V) oxide.

Step2: Determine indium oxidation states for oxides

Indium ($In$) commonly has oxidation states of +1 and +3. For the oxide with the fewest oxygen atoms, when $In$ has an oxidation state of +1, and oxygen has an oxidation state of -2, using the criss - cross method for ionic compounds, the formula is $In2O$. When $In$ has an oxidation state of +3, the formula is $In2O3$.

Step3: Determine the formula for calcium - phosphorus compound

Calcium ($Ca$) has an oxidation state of +2 and phosphorus ($P$) can form phosphide with an oxidation state of -3 in binary ionic compounds. Using the criss - cross method, the formula is $Ca3P2$.

Answer:

Question 8: Vanadium(V) oxide
Question 9: In2O
In2O3
Question 10: Ca3P2
