Calculate the kinetic energy of a mole of oxygen gas molecules that have a speed
of 10.0 m/s.

1600J

Explanation:

1 mole of oxygen gas (O2) has a mass of 32g i.e. the molar mass = 32g/mol

Kinetic energy (K.E) = ½ × m × v²

Where;

m = mass (g)

v = speed or velocity (m/s)

From the information given in this question;

m = 32g

V = 10m/s²

K.E = ½ × 32 × 10²

K.E = 16 × 100

K.E = 1600J

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.
