Consider the following reaction: Mg(s) + 2HCl(aq) —> MgCl2(aq) + H2(g)

What happens to the collisions as the temperature of the above system increases?

Collisions decrease and fewer are effective.
Collisions decrease and fewer are effective.

Collisions increase and more are effective.
Collisions increase and more are effective.

Collisions increase but fewer are effective.
Collisions increase but fewer are effective.

Collisions decrease but more are effective.

where is the following

explanation:

d. temperate deciduous forest

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

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.
