The rate of reaction between zn(s)zn(s) and hcl(aq)hcl(aq) is determined by measuring the volume of h2(g)h2(g) produced over time. in trial 2 of the experiment, 5.0g5.0g of powdered zn(s)zn(s) is added to 100ml100ml of 0.10mhcl(aq)0.10mhcl(aq). which trial will have a faster initial rate of reaction and why?

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
