What two terms best describe the variable "air pressure inside the football"

dependent, quantitative

Explanation:

The air pressure inside the football is the dependent variable as it depends upon the size and shape of the football. The dependent variable is the one which can be changed or manipulated due to the changes in the independent variable. The independent variable can be manually changed and manipulated.

The quantitative variable is the variable which can be measured in units and counted in numbers. The air pressure in the football can be measured in the football in pascals.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
