**gas laws**

A balloon contains 10.0g of neon gas. With T kept constant, 10.0g of argon gas is added, and the volume of the balloon expands by less than 2 times. Why?

What equation would I use to solve this problem: The volume of a balloon is 3.78 L at 22.8°C. The balloon is heated to 42.4°C. Calculate the new volume of the balloon.

Would I use half reactions to balance: Cl_2 --> Cl- + ClO_3- ?

**Chem 1A**

So, after I did the half-reactions, I still only got a coefficient for NO_3- to be 1, yet in the answer key provided (this is a practice midterm question), it says the coefficient is 6....I'm confused as to how you are supposed to figure that out.

**Chem 1A**

The following reaction occurs in aqueous acid solution: NO3– +I– →IO3– +NO2 In the balanced equation, using the smallest whole-number coefficients, what is the coefficient of NO3–?
