Express in scientific notation (6.0x10^4) (3.1x10^-1)

The Answer is: 1.86×10^4

1.86 x 104

Explanation:

This mathematical operation is a multiplication, so:

1.- Multiply the number as usual: 6 x 3.1 = 18.6

2.- Multiply the coefficients, remember since they coefficients, a multiplication, actually you need to add them: 4 + (-1) = 3+

3.- Then you write the number with the coefficient: 18.6 x 103

4.- In this case since the scientific notation just admit one number will be:

1.86 x 104

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.
