Ineed with 1,2,3 questions on chemistry

1. Physical Intensive

2. Chemical

3. Physical Extensive

Explanation:

1 is physical intensive because it can be known without undergoing a chemical reaction therefore its physical and the colour doesn't depend on the amount of the substance there therefore it is intensive.

2 is chemical because it must undergo a chemical reaction in order to know.

3 is physical because it can be known without undergoing a chemical reaction and it is extensive because it is dependant on the amount of substance being measured.

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.
