You are trying to determine the volume of the balloon needed to match the density of the air in the lab. You know that if you ca
9966 [12]

To solve this problem, we must be given first the density of air at 20 degrees Celsius. Looking up online, this is equal to:

density air (20C) = 0.0012041 g/mL

so that the volume is:

volume balloon = 0.57 g / (0.0012041 g/mL)

<span>volume balloon = 473.38 mL</span>

The anion of which element has a –1 charge?
vovangra [49]
An anion is a negatively charged ion. An element can become an anion if it takes an extra electron such that it has one more electron than protons.
Atoms would preferentially taken an extra electron so that it can have a full octet and be more stable.

\sf Cl^-, Br^-, F^- are some of the few elements that would have a -1 charge.
