c. If the average basal rate of oxygen consumption for an adult is 15 L/hour, then calculate how many hours of oxygen use will you get from the 4.7 L tank?

0.3hrs

Explanation:

Given parameters:

Average basal rate  = 15L/hr

Volume of oxygen  = 4.7L

Unknown:

Hours of oxygen use  = ?

Solution:

Now to solve this rate problem, we need to find the time;

 Hours of oxygen use  =  

 Hours of oxygen use  =   = 0.3hrs

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.

the answer is barium and copper bromide
