Which of the following questions can be answered by science? a. is fruit ripening dependent on the type of light the fruit is exposed to? b. is it justifiable to add chemicals to the atmosphere to stimulate rain? c. do art and beauty provide a soul-stirring experience to humans? d. do scientists have the right to edit human dna?

A. Is fruit ripening dependent on the type of light the fruit is exposed to, because B, C, and D are all based on opinion and different mind sets whereas A can be found out through experimentation.

A because the rest you are asking for people's opinions

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

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.
